The Digital Sound Field Processor (DSP) built into this unit takes full advantage of Yamaha’s undisputed leadership in the field of digital audio processing to bring you a whole new world of listening experiences. Follow the instructions in this manual carefully when setting up your system, and this unit will sonically transform your room into a wide range of listening environments –movie theater, concert hall, and so on. In addition, you get incredible realism from Dolby-encoded video sources using the built-in Dolby Pro Logic Surround Decoder. Rather than tell you about the wonders of digital sound field processing, however, let’s get right down to the business of setting up the system and trying out its many capabilities. Please read this operation manual carefully and store it in a safe place for later reference. Digital Sound Field Processing What is it that makes live music so good? Today’s advanced sound reproduction technology lets you get extremely close to the sound of a live performance, but chances are you’ll still notice something missing: the acoustic environment of the live concert hall. Extensive research into the exact nature of the sonic reflections that create the ambience of a large hall has made it possible for Yamaha engineers to bring you this same sound in your own listening room, so you’ll feel all the sound of a live concert. What’s more, our technicians, armed with sophisticated measuring equipment, have even made it possible to capture the acoustics of a variety of venues such as an actual concert hall, theater, etc. to allow you to accurately recreate one of several actual live performance environments, all in your own home. Dolby Pro Logic Surround The Dolby Pro Logic Surround Decoder program lets you experience the dramatic realism and impact of Dolby Surround movie theater sound in your own home. Dolby Pro Logic gets its name from its professional-grade steering logic circuitry, which provides greater effective channel separation for a much higher degree of realism than the “passive” Dolby Surround circuits found in today’s typical home audio/video equipment. Dolby Pro Logic Surround provides a true center channel, so that there are four independent channels, unlike passive Dolby Surround which has in effect only three channels: left, right, and rear. This center channel allows listeners seated in even less-than-ideal positions to hear the dialog originating from action on the screen while getting a stereo effect as well. This Dolby Pro Logic Surround Decoder employs a digital signal processing system. This system increases sound stability at each channel and minimizes crosstalk between channels compared to conventional analog Dolby signal processing. In addition, this unit features a built-in automatic input balance control. This circuit always presents you the best surround conditions without performing manual adjustments. “ENHANCED” Dolby Pro Logic Surround This unit has a second mode of Dolby Pro Logic Surround processing called “Enhanced Dolby Pro Logic Surround” processing. Enhanced Dolby Pro Logic Surround processing recreates the surround effect of a movie theater, effectively duplicating its multiple surround loudspeaker system, completely surrounding the listener with the sounds of the action taking place on the screen. 5  SPEAKER SETUP FOR THIS UNIT SPEAKERS TO BE USED This unit is designed to provide the best sound-field quality with a 5 speaker configuration. The speakers to be used with this unit will be mainly front speakers, rear speakers, and a center speaker. (You can omit the center speaker. Refer to the “4-Speaker Configuration” shown below.) The front speakers are used for the output of the main source sound and the effect sound. They will probably be the speakers of your present stereo speaker system. The rear speakers are used for the output of the effect sound. And the center speaker is used for the output of the center sound (dialog etc.) encoded with the Dolby Surround. The rear and center speakers do not need to be equal in power to the front speakers. However, all the speakers should have high enough power handling to accept the maximum output of this unit. SPEAKER CONFIGURATION 5-Speaker Configuration 4-Speaker Configuration This configuration is the most effective and is the one that is recommended. In this configuration, the center speaker is necessary as well as the rear speakers. If the digital sound field program is in DOLBY PRO LOGIC or ENHANCED mode conversations will be output from the center speaker and the ambience will be excellent. ● Set the center mode to the “NORMAL” or “WIDE” position. (For details, refer to page 11.) The center speaker is not used in this configuration. If the digital sound field program is in the DOLBY PRO LOGIC or ENHANCED mode, the center sound is output from the left and the right front speakers. However, the sound effect of other programs can be the same as that of the 5-speaker configuration. ● Be sure to set the center mode to the “PHANTOM” position. (For details, refer to page 11.) Front L Center Front R Front L Dialogue Dialogue Surround sound Surround sound Rear L Rear R Rear L Front R Rear R SPEAKER PLACEMENT The recommanded speaker configuration, the 5-speaker configuration, will require two speaker pairs: front speakers (your normal stereo speakers), and rear speakers, plus a center speaker. When you place these speakers, refer to the following. Front: Front R Center Front L TV set Rear R Rear L 6 In normal position. (The position of your present stereo speaker system.) Rear: Behind your listening position, facing slightly inward. Nearly six feet (approx. 1.8 m) up from the floor. Center: Precisely between the front speakers. (To avoid interference with TV sets, use a magnetically shielded speaker. If, however, it is not effective, keep the speaker away from TV sets.)  CONNECTIONS Before attempting to make any connections to or from this unit, be sure to first switch OFF the power to this unit and to any other components to which connections are being made. CONNECTIONS WITH OTHER COMPONENTS When making connections between this unit and other components, be sure all connections are made correctly, that is to say L (left) to L, R (right) to R, “+” to “+” and “–” to “–”.

If the connections are faulty, no sound will be heard from the speakers. Make sure that the polarity of the speaker wires is correct, that is, + and – markings are observed. If these wires are reversed, the sound will be unnatural and will lack bass. Do not let the bare speaker wires touch each other and do not let them touch the metal parts of this unit as this could damage this unit and/or speakers. ● Use speakers with the specified impedance shown on the rear of this unit. Note for front speaker connection: One or two speaker systems can be connected to this unit. If you connect only one speaker system, connect it to either the FRONT A or B terminals. How to Connect: Red: positive (+) Black: negative (–) ➀ Press and hold the tab. ➁ Insert the bare wire. [Remove approx. 5mm (1/4”) insulation from the speaker wires.] ➂ Release the tab and secure the wire. ABOUT THE ACCESSORY TERMINALS AC OUTLETS FRONT OUT terminals (U.S.A., Canada and General models) .......................................................... 2 SWITCHED OUTLETS (Australia model).................................. 1 SWITCHED OUTLET Use these to connect the power cords from your components to this unit. The power to the SWITCHED outlets is controlled by this unit’s POWER switch or the provided remote control transmitter’s POWER key. These outlets will supply power to any component whenever this unit is turned on. The maximum power (total power consumption of components) that can be connected to the SWITCHED AC OUTLETS is 100 watts (80 watts for Canada model). These terminals are for front-channel line output. Leave the jumper bars connected to FRONT IN terminals when you use the built-in amplifier. However, if you drive front speakers with an external stereo power amplifier, remove the jumper bars and connect the input terminals of the external amplifier (MAIN IN or AUX terminals of a power amplifier or an integrated amplifier) to these terminals. REMOTE CONTROL (PHONO) connector If you have a YAMAHA turntable with the terminal for remote control, connect it to this connector by using the cable provided with the turntable. This connection allows you to control the turntable from the provided remote control transmitter. GND terminal (For turntable use) Connecting the ground wire of the turntable to this terminal will minimize hum, but in some cases better results may be obtained with the ground wire disconnected. 8 FRONT IN terminals These terminals are for line input to the built-in front-channel amplifier. Leave the jumper bars connected to FRONT OUT terminals when you use the built-in amplifier. However, if you drive front speakers with an external stereo power amplifier, remove the jumper bars. EFFECT OUT (REAR) terminals These terminals are for rear-channel line output. There is no connection to these terminals when you use the built-in amplifier. However, if you drive rear speakers with an external stereo power amplifier, connect the input terminals of the external amplifier to these terminals. If you use the built-in amplifier and the external power amplifier at the same time, the sound will be output through both speakers.  ANTENNA CONNECTIONS ● ● Each antenna should be connected to the designated terminals correctly, referring to the following figure. Both AM and FM indoor antennas are included with this unit. In general, these antennas will probably provide sufficient signal strength. Nevertheless, a properly installed outdoor antenna will give clearer reception than an indoor one. If you experience poor reception quality, an outdoor antenna may result in improvement. Outdoor FM antenna Indoor FM antenna (included) Outdoor AM antenna AUDIO SIGNAL GND 300-ohm feeder AM loop antenna (included) PHONO 75Ω FM UNBAL ANT GND CD AM ANT 75-ohm coaxial cable 75-ohm/300-ohm antenna adapter TAPE PB TAPE 1 REC OUT Ground Connecting the AM loop antenna 1 2 ➀ 3 ➂ Orient so that the best reception is obtained. ➁ * The AM loop antenna should be placed apart from the main unit. The antenna may be hung on a wall. * The AM loop antenna should be kept connected, even if an outdoor AM antenna is connected to this unit. GND terminal For maximum safety and minimum interference, connect the GND terminal to a good grounding. A good grounding is a metal stake driven into moist earth. Notes When connecting the indoor FM antenna, make sure that the grooved part of the connector hole is facing downward. ● ● If you need an outdoor FM antenna to improve FM reception quality, either a 300-ohm feeder or a coaxial cable may be used. In locations troubled by electrical interference, a coaxial cable is preferable. 9  ADJUSTMENT BEFORE OPERATION Speaker balance adjustment This procedure lets you adjust the sound output level balance between the front, center, and rear speakers using the built-in test tone generator. With this adjustment, the sound output level heard at the listening position will be the same from each speaker. This is important for the best performance of the digital sound field processor. The adjustment of each speaker output level should be done at your listening position with the remote control transmitter. Otherwise, the result may not be satisfactory. 6 1 5 6 2 3 1 4 4 VOLUME BALANCE 0 L 5 5 R –dB 0 Set to “0”. ∞”. Set to “ 5 2 Select the front speakers to be used.

R TEST Adjustable. 12 Notes ● The FRONT EFFECT LEVEL key does not function if the unit is in the “test” mode. Because the effect sound output level of the front speakers is used as the basis in speaker balance adjustment. ● Once you have completed these adjustments, you can adjust whole sound level on your audio system by using the VOLUME control (or the MASTER VOLUME keys on the remote control transmitter). ● If you use external power amplifiers, their volume controls may also be adjusted to achieve proper balance. ● In step 12, if the center mode is in the “PHANTOM” position, the sound output level of the center speaker can not be adjusted. This is because in this mode, the center sound is automatically output from the left and right front speakers.  2 OPERATIONS Display 3 Tuner controls 1, 6 PHONES jack 4 To play a source 1 7 VOLUME ∞” . 0 –dB Set to— dB“ 2 3 Select the desired input source.

Description of Each Sound Field Program PROGRAM PRO LOGIC ENHANCED This program reproduces sources encoded with the Dolby Surround. Enhancing the “Normal” Dolby Pro Logic, the DSP technology simulates the multi-surround speaker systems of a 35 mm film theater, thus widening the surrounded-sound field with greater presence. CONCERT VIDEO This program is effective for music videos and gives excellent depth and clarity for vocals. For opera, the orchestra and stage are ideally recreated, letting you feel as if you were in an actual concert hall. MONO MOVIE This program is designed specifically to enhance mono source programs. Compared to a strictly mono setting, the sound image created in this mode is wider and slightly forward of the speaker pair, lending an immediacy to the overall sound. It is particularly effective when used with old mono movies, news broadcasts and dialog. ROCK CONCERT This program is suitable for rock music. A big, powerful sound is reproduced lively and dynamically. CONCERT HALL In this program, the center seems even more deeply behind the front speaker pair, creating an expansive, large hall ambience. OFF 18 FEATURE This program reproduces sources encoded with the Dolby Surround. The employment of the digital signal processing system improves crosstalk and transfers the sound source more smoothly and precisely, compared to the conventional type. A stable movie sound field is recreated. When any program is not used with the selected source, press this switch. The sound is output only from the front speakers.  Notes on Operation of Sound Field Programs ● In the CONCERT VIDEO, MONO MOVIE, ROCK CONCERT and CONCERT HALL modes, no sound is heard from the center speaker. ● When a monaural sound source is played in the DOLBY PRO LOGIC or ENHANCED mode, no sound is heard from the front speakers and the rear speakers. Sound is heard only from the center speaker. However, if the center mode is in the PHANTOM, the front speakers output the sound of the center speaker. ● If you connect an external amplifier to this unit, see if it has built-in surround sound or ambience circuitry. If it does, then be sure that the surround or ambience circuitry on that amplifier is off while you are using the digital sound field processor’s Dolby Pro Logic Surround decoding function. ● When this unit is in the Dolby Pro Logic Surround mode, if the main-source sound is considerably altered by overadjustment of the BASS or TREBLE controls, the relationship between the center and rear channels may produce an unnatural effect. Description of Dolby Pro Logic Surround DOLBY PRO LOGIC SURROUND: This unit employs the Dolby Pro Logic Surround system. This system is similar to professional Dolby Stereo decoders used in movie theaters. By employing a four-channel system, the Dolby Pro Logic Surround system divides the input signals into four levels: the left and right main channels, the center channel (to characterize dialog), and the rear surround-sound channels (to characterize sound effects, background noise and other ambient noise). Dolby Surround is encoded on the sound track of commercially available video cassettes and video discs as well. When you play a source encoded with Dolby Surround on your home video system, the Dolby Pro Logic Surround mode on this unit decodes the signal and feeds the surround-sound effects. The Dolby Pro Logic Surround mode may not be always effective on video sources not encoded with Dolby Surround. Manufactured under license from Dolby Laboratories Licensing Corporation.

(For details, refer to the corresponding descriptions on this page and the next page.) Select the desired program that is suitable for the source. Note If you prefer to cancel the selected program, press the OFF switch. The sound will be the normal 2-channel stereo without surround sound effect. PRO LOGIC Adjustment of DELAY TIME You can adjust the time difference between the beginning of the source sound and the beginning of the effect sound with the DELAY TIME control. The DELAY TIME control is effective with all programs. By applying more or less delay, sound effects, background noise, and ambient noise coming at you from the rear speakers can be enhanced or subdued for extra effect. 1. PRO LOGIC: 2. ENHANCED: 3. CONCERT VIDEO: 4. MONO MOVIE: 5. ROCK CONCERT: 6. CONCERT HALL: 20 from 15 to 30 milliseconds (Preset value: 20 milliseconds) from 15 to 30 milliseconds (Preset value: 20 milliseconds) from 1 to 100 milliseconds (Preset value: 25 milliseconds) from 1 to 100 milliseconds (Preset value: 25 milliseconds) from 1 to 100 milliseconds (Preset value: 15 milliseconds) from 1 to 100 milliseconds (Preset value: 30 milliseconds) By continuously pressing “+” or “–” on the DELAY TIME control, the value changes continuously. However, the value stops changing momentarily at the preset point. DELAY TIME DELAY ms Adjustable Note Adding too much delay will cause an unnatural effect with some sources. Experiment with the DELAY TIME control to create the effect that you find most suitable.  Adjustment of the FRONT EFFECT LEVEL If desired, you can adjust the effect sound output level of the front speakers with this control. The output level is preset to be 80. However, you can adjust the level between 1 and 100. ● If the digital sound field program is in the DOLBY PRO LOGIC mode, the FRONT EFFECT LEVEL control does not function. ● Once the output level is adjusted, the level value will be the same in all the digital sound field programs except for the DOLBY PRO LOGIC . ● If a digital sound field program is not used, the FRONT EFFECT LEVEL control does not function. ● By continuously pressing “+” or “–” on the CENTER LEVEL control, the level value changes continuously. However, the value stops changing momentarily at the point which was once set in the “test” mode. ● If the digital sound field program is in the CONCERT VIDEO, MONO MOVIE, ROCK CONCERT or CONCERT HALL mode, the CENTER LEVEL control can not function. ● Once the output level is adjusted, the level value will be the same in the DOLBY PRO LOGIC and ENHANCED modes. ● If a digital sound field program is not used, the CENTER LEVEL control does not function. ● By continuously pressing “+” or “–” on the REAR LEVEL control, the level value changes continuously. However, the value stops changing momentarily at the point which was once set in the “test” mode. ● Once the output level is adjusted, the level value will be the same in all the digital sound field programs. ● If a digital sound field program is not used, the REAR LEVEL control does not function. FRONT EFFECT LEVEL F Illuminates Adjustable Adjustment of the CENTER LEVEL If desired, you can adjust the sound output level of the center speaker with this control even if the output level is already set in “Speaker balance adjustment” on page 10. CENTER LEVEL C Illuminates Adjustable Adjustment of the REAR LEVEL If desired, you can adjust the sound output level of the rear speakers with this control even if the output level is already set in “Speaker balance adjustment” on page 10. REAR LEVEL R Illuminates Adjustable Note The values of the DELAY TIME, the FRONT EFFECT LEVEL, CENTER LEVEL, and REAR LEVEL you set the last time will remain memorized even when the power of this unit is off. However, if the power plug cord is kept disconnected for more than one week, these values will be invalid. 21  SETTING THE SLEEP TIMER If you use the SLEEP timer of this unit, you can set this unit to be turned off automatically. When you are going to sleep while enjoying a broadcast or other desired input source, this timer function is helpful. Notes ● The SLEEP timer can be controlled only with the remote control transmitter. ● The components on which the SLEEP timer is effective are the sources connected to a SWITCHED OUTLET on the rear panel of this unit. To set the SLEEP time To cancel the selected SLEEP time 1 Press once when the SLEEP time displays 30. SLEEP Indicates the SLEEP time. SLEEP Flashes on and off continuously. Returns to the indication before the SLEEP timer is set. Select the desired SLEEP time. Whenever the SLEEP key is pressed, the SLEEP time will change as follows. (Minutes) 120 90 60 30 The SLEEP timer is OFF. (The indication before the SLEEP key is pressed.) After a while, the display returns to the indication before the SLEEP timer is set, and the “SLEEP” indicator stops flashing and illuminates. 2 22 The unit will be turned off automatically after the passing of the SLEEP time you selected. Goes off.  REMOTE CONTROL TRANSMITTER The provided remote control transmitter is designed to control this unit and other YAMAHA components. If the CD player, turntable, LD player and tape deck connected to this unit are YAMAHA components, then this remote control transmitter will also control various functions of each component. Moreover, this remote control transmitter can learn various functions from other remote control transmitters without losing the preset key functions. If you use this “learning” function, you will no more need so many remote control transmitters to control various components to be used. For details, refer to page 25. KEY FUNCTIONS When you operate this unit and/or other YAMAHA components with this remote control transmitter, set the YPC-USER-LEARN switch to the YPC (Yamaha Preset Code) position.

By using this feature, this unit can then be used in place of one or more other remote control transmitters, thus making operation of your various audio and video components more convenient. Use the included user program sheets to indicate a new function learned for each key. Note There may occasionally be instances in which, due to the signal-coding and modulation employed by the other remote control transmitter, this unit will not be able to “learns” its signals. To Learn a New Function 1 Set to “LEARN”. 2 Press a key on this unit where a new function will be learned. Other remote control transmitter This unit 3 About 5–10 cm (2–4 in.) Press and hold the key (on the other remote control transmitter) where the desired new function is. When the TRANSMIT/LEARN indicator stops illuminating, the learning is finished. 4 Repeat the step 2–3 unit all desired funfunctions are successfully learned. 5 Set to “USER” . Try operating your components. Notes ● When you operate the desired component with this remote control transmitter, TRANSMIT/LEARN indicator will flash steadily. ● The originally preset function of a key is still available in the USER position if a new function has not been learned to the key. ● Successful learning to a key results in the erasure of previously learned functions and their replacement by the newly learned ones. ● If there is no more room in the memory area for a function to be learned, the TRANSMIT/LEARN indicator will flash two times. In this case, even if some keys are not occupied with functions from other remote control transmitters, no further learning is possible. Memory back-up All of the learned functions will be retained while you replace the batteries. However, if no batteries are installed for a few hours, the learned functions will be erased and will have to be learned again. Blank keys (Refer to page 23.) These keys have no preset functions and are used only for learning other remote control transmitter’s functions. YPC-USER-LEARN switch (Refer to page 23.) YPC: Set to this position when using preset key functions (for controlling this unit and/or YAMAHA components). * “YPC” is the abbreviation of YAMAHA Preset Code. USER: Set to this position when using “learned” key functions. LEARN: Set to this position when learning new key functions from other remote control transmitters. RESET button (Refer to page 23.) Press this button to “reset” the internal microcomputer which controls remote control operations. Microcomputer “reset” is necessary when the remote control freezes. * Pressing the RESET button will not erase learned functions. 25  To Clear a Learned Function 1 To Clear All Learned Functions 1 Set to “USER”. 2 Press and hold the CLEAR button using the point of a mechanical pencil, etc. Set to “LEARN”. 2 CLEAR 3 Press and hold the CLEAR button using the point of a mechanical pencil, etc. CLEAR Press and hold the key where the learned function to be deleted is until the indicator flashes 3 times. 3 Press and hold any key until the indicator flashes 7 times. TRANSMIT /LEARN TRANSMIT /LEARN To clear two or more functions, repeat step 2 and 3. Note If a key is not pressed soon after the CLEAR button is pressed, this unit will automatically return to the status that was in effect before the CLEAR button was pressed. NOTES ABOUT THE REMOTE CONTROL TRANSMITTER Battery installation Remote control transmitter operation range 2 1 3 Remote control sensor Battery replacement Within approximately 7 m (23 feet) If you find that the remote control transmitter must be used closer to the main unit, the batteries are weak. Replace both batteries with new ones. Notes ● Use only AA, LR6, UM-3 batteries for replacement. ● Be sure the polarities are correct. (See the illustration inside the battery compartment.) ● Remove the batteries if the remote control transmitter will not be used for an extended period of time. ● If batteries leak, dispose of them immediately. Avoid touching the leaked material or letting it come in contact with clothing, etc. Clean the battery compartment thoroughly before installing new batteries. 26 30° 30° Notes ● There should be no large obstacles between the remote control transmitter and the main unit. ● If the remote control sensor is directly illuminated by strong lighting (especially an inverter type of fluorescent lamp etc.), it might cause the remote control transmitter not to work correctly. In this case, reposition the main unit to avoid direct lighting.  TROUBLESHOOTING If the unit fails to operate normally, check the following points to determine whether the fault can be corrected by the simple measures suggested. If it cannot be corrected, or if the fault is not listed in the SYMPTOM column, disconnect the power cord and contact your authorized YAMAHA dealer or service center for help. Amplifier SYMPTOM CAUSE Power cord is not plugged in or is not completely inserted. Firmly plug in the power cord. No sound or no picture. Incorrect output cord connections. Connect the cords properly. If the problem persists, the cords may be defective. The MUTING switch is ON. First, turn the volume control to full left. Then, turn the MUTING switch OFF with the remote control transmitter and adjust the volume. Appropriate input selector is not pressed. Press the appropriate input selector corresponding to the input source. The sound suddenly goes off. The protection circuit has activated because of short circuit etc. Turning the unit off and then on will reset the protection circuit. Only one side speaker outputs the sound. Incorrect setting of the BALANCE control. Adjust it to the appropriate position. Incorrect cord connection. Connect cord properly. If the problem persists, the cables may be defective. Incorrect cord connections. Firmly connect the audio plugs. If the problem persists, the cord may be defective. No connection from the turntable to the GND terminal. Make the GND connection between the turntable and this unit. The volume level is low while playing a record. The record is being played on a turntable with an MC cartridge. The player should be connected to the unit through the MC head amplifier. No sound from the rear speakers. The sound output level of the rear speakers is 0. Turn up the sound output level with the REAR LEVEL key. The monaural sound source is played in DOLBY PRO LOGIC or ENHANCED mode. Select another program suitable for the monaural sound source. The sound output level of the center speaker is 0. Turn up the sound output level with the CENTER LEVEL key. The center mode is in PHANTOM mode. Select NORMAL or WIDE. Sound “hums”. No sound from the center speaker. Incorrect sound field program selection. No sound field program is selected. FM REMEDY The unit fails to turn on when the POWER switch is pressed. Select the appropriate program. FM stereo reception is noisy. Because of the characteristics of FM stereo broadcasts, this is limited to cases where the transmitter is too far away or the antenna input is poor. Check the antenna connections. Try using a multiple element FM antenna. There is distortion and clear reception cannot be obtained even with a good FM antenna. There is multipath interference. Adjust antenna placement to eliminate multipath interference. A desired station cannot be tuned in with Auto tuning. The station is too weak. Use Manual tuning mode. Use a high quality directional FM antenna. A desired station cannot be tuned in with Auto tuning. Weak signal or loose antenna connections. Tighten the AM loop antenna connections and rotate it for best reception. There are continuous crackling and hissing noises. Noises will result from ligtning, fluorescent lamps, motors, thermostats and other electrical equipment. Use an outdoor antenna and a ground wire. This will help somewhat but it is difficult to eliminate all noise. There are buzzing and whining noises (especially in the evening). A television set is being used nearby. Move the television away. The remote control transmitter does not work. Direct sunlight or lighting (of an inverter type of flourescent lamp etc.) is striking the remote control sensor of the main unit. Change the position of the main unit. The distance or range within which the remote control transmitter can be used decreases. The batteries of this remote control transmitter are too weak. Replace the batteries with new ones. The batteries of the other remote control transmitter are weak. Replace the batteries. The distance between the two remote control transmitters is too long or too short. Place the remote control transmitters with the proper distance. Power cord of this unit is not plugged in. Plug in the power cord. Others Remote control transmitter AM Use Manual tuning mode. The TRANSMIT/LEARN indicator does not illuminate or flash. Learning cannot be made successfully. The sound is degraded when monitoring is performed by using the headphones connected to the compact disc player or cassette deck which are connected with this unit. 27  SPECIFICATIONS AUDIO SECTION
