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. Dolby Pro Logic Surround + DSP You can also enjoy Dolby Pro Logic with two modes of Digital Surround field processing. These combinations expand the surround effect. One is the “ENHANCED” Dolby Pro Logic Surround, which recreates the surround effect of the 35 mm film movie theater. The other is the combination of Dolby Pro Logic and the sound field program “70 mm MOVIE THEATER”, which recreates the listening experience of a 70 mm film theater. Directional Enhancement Circuit + DSP The newly featured directional enhancement circuit expands and focuses the digital sound field by emphasizing position of sound. This effect puts you in the midst of the action, while centering and focusing your attention to the screen. This circuit is available on the sound field program “TV THEATER”. 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 (most important effects as well as dialogue) 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, ENHANCED or TV THEATER 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 13.) The center speaker is not used in this configuration. If the digital sound field program is in the DOLBY PRO LOGIC, ENHANCED or TV THEATER 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 13.) 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 R Center Front: 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 “–”. Also, refer to the owner’s manual for each component to be connected to this unit. Front speakers A Center speaker(s) LD player Video cassette recorder 1 Right Left Compact disc player (U.S.A. model) Turntable Tape deck 1 To AC outlet Right Left Right Video cassette recorder 2 or tape deck 2 Monitor TV Front speakers B Left Rear speakers : Refer to “ABOUT THE ACCESSORY TERMINALS” on page 10. 7  CONNECTING S VIDEO TERMINALS If your video cassette recorder, video disc player, etc. and your monitor are equipped with “S” (high-resolution) video terminals, connect them to this unit’s S VIDEO terminals, and connect this unit’s S VIDEO MONITOR OUT terminal to the “S” video input of your monitor. Otherwise, connect the composite video terminals from your video cassette recorder, video disc player, etc. to the composite video terminals of this unit, and connect this unit’s composite MONITOR OUT terminal to the composite video input of your monitor. Note If video signals are sent to both S VIDEO input and composite input terminals, the signals will be sent to their respective output terminals independently. LD player Video cassette recorder 2 Video cassette recorder 1 Monitor TV ON SCREEN DISPLAYS If you connect your video cassette recorder, video disc player, video monitor, etc. to this unit, you can take advantage of this unit’s capability to display DSP program names and information about other various settings and adjustments on your video monitor’s screen. This information will be superimposed over the video image. If there is no video source connected or it is turned off, the information will be displayed over a monochromatic background. Notes ● If you watch a video source that is connected to both S VIDEO and composite video input terminals of this unit, signals of screen display information are output from only the S VIDEO MONITOR OUT terminal. ● When no video signal is input to either S VIDEO input or composite video input terminals of this unit, signals of screen display information are output from both S VIDEO MONITOR OUT and composite MONITOR OUT terminals with a monochromatic background. * For the General Model, if the PAL/NTSC switch on the rear panel is set to “PAL”, nothing will be output from either S VIDEO MONITOR OUT or composite MONITOR OUT terminal in this case. 8  CONNECTING SPEAKERS Connect the SPEAKERS terminals to your speakers with wire of the proper gauge, cut to be as short as possible. 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. How to Connect: Red: positive (+) Black: negative (–) ➀ Unscrew the knob. ➁ Insert the bare wire. 2 3 1 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. Rear speaker connection: One rear speaker system can be connected to the REAR terminals. Center speaker connection: One or two center speakers can be connected to this unit. If you connect only one center speaker, connect it to either the CENTER C or D terminals. While connecting, be sure to set the CENTER speaker impedance switch to the proper position. Set to “C + D” when using two center speakers, or to “C OR D” when using only one center speaker. If the switch is set to the improper position, no sound may be heard from the center speaker. [Remove approx. 5mm (1/4") insulation from the speaker wires.] ➂ Tighten the knob and secure the wire. C D C OR D * Banana Plug connections are also possible. Simply insert the Banana Plug connector into the corresponding terminal. USING AUX TERMINALS (ON THE FRONT PANEL) <for RX-V1070 only> These terminals are used to connect an auxiliary video input source such as a camcorder to this unit. AUDIO OUT R AUDIO OUT L VIDEO OUT VIDEO Camcorder 9  ABOUT THE ACCESSORY TERMINALS AC OUTLETS FRONT OUT terminals (U.S.A., Canada and General models) ......... 2 SWITCHED OUTLETS and 1 UNSWITCHED OUTLET (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 power to the UNSWITCHED outlet can not be controlled by this unit’s POWER switch or the provided remote control transmitter’s POWER key. 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. <U.S.A. and General models> The maximum power (total power consumption of components) that can be connected to the SWITCHED AC OUTLETS is 100 watts. The maximum power (total power consumption of components) that can be connected to the UNSWITCHED AC OUTLET is 200 watts. <Canada model> The maximum power (total power consumption of components) that can be connected to the SWITCHED AC OUTLETS is 120 watts. The maximum power (total power consumption of components) that can be connected to the UNSWITCHED AC OUTLET is 180 watts. 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. REAR OUT terminals These terminals are for rear-channel line output. If you use the built-in amplifier, there is no connection to these terminals. 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 only through the external one. <Australia model> CENTER OUT terminal The maximum power (total power consumption of components) that can be connected to the SWITCHED AC OUTLET is 100 watts. This terminal is for center-channel line output. There is no connection to this terminal when you use the built-in amplifier. However, if you drive a center speaker with an external power amplifier, connect the input terminal of the external amplifier to this terminal. If you use the built-in amplifier and the external power amplifier at the same time, the sound will be output only through the external one. 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. 10 FRONT IN terminals LOW PASS terminal This terminal is for output to a mono amplifier driving a subwoofer. Frequencies above 200 Hz are filtered out so that only the bass range remains.  ● ● 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 ENGLISH ANTENNA CONNECTIONS Outdoor AM antenna Indoor FM antenna (included) AM loop antenna (included) 300-ohm feeder 75-ohm coaxial cable 75-ohm/300-ohm antenna adapter Ground Connecting the AM loop antenna 1 2 3 ➀ Orient so that the best reception is obtained. ➂ 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. 11  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. * If your monitor is connected to this unit, by turning it on, display information and image on the monitor’s screen will help you to perform this adjustment. 6 1 5 6 2 4 3 Illustrations: RX-V1070 Parts in shaded areas ( ) are not present on RX-V870. 4 1 ∞”.

Notes ● A new setting can be programmed in place of the former one. ● For presets, the setting of the reception mode (stereo or monaural) is stored along with the station frequency. Memory back-up The memory back-up circuit prevents the programmed data from being lost even if the POWER switch is turned off or the power plug is disconnected from the AC outlet or the power is cut due to temporary power failure. If, however, the power is cut for more than two weeks, the memory may be erased. If so, it can be re-programmed simply by following the PRESET TUNING steps.  USING DIGITAL SOUND FIELD PROCESSOR (DSP) This unit incorporates a sophisticated, multi-program digital sound field processor, which allows you to expand and shape the audio sound field from both the audio and video sources, for a theater-like experience in the listening/viewing room. This digital sound field processor has 8 programs; 4 programs for audio sources and 4 programs for Audio/Video sources. You can create an excellent audio sound field by selecting the suitable program and adding desired adjustments. In addition, when the digital sound field program is in the DOLBY PRO LOGIC, ENHANCED or 70 mm MOVIE THEATER mode, the built-in automatic input balance control functions. This presents you the best surround condition without manual adjustment. Selects center mode. (For details, refer to page 13.) Displays your selection on the DSP or other informations.

(For details, refer to page 22–23.) 19  Description of Each Sound Field Program PROGRAM PRO LOGIC ENHANCED 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. 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. 70 mm MOVIE THEATER The Yamaha DSP technology is ideally combined with the Dolby Pro Logic to present you incredible listening experience of the 70 mm film movie theater. This program is ideal for precisely reproducing the sound design of the newest movies. The sound field is made according to the design of the newest movie theaters, so the reverberations of the sound field itself are restrained as much as possible. The three dimensional feeling of the sound field is emphasized, and dialog is precisely oriented on the screen. You can enjoy watching S.F.X., adventure movies, etc. with this program. TV THEATER This program simulates the sound field of a jazz or rock concert. By featuring the directional enhancement circuit, vocals are oriented on the screen and the sound field is widely expanded. Your attention will be focused on the screen in enthusiastic atmosphere, as if attending an actual jazz or rock concert. ROCK CONCERT JAZZ CLUB CHURCH This program is suitable for rock music. A big, powerful sound is reproduced lively and dynamically. This is a small, cozy jazz club with a low ceiling. The sound is very close and intimate. This program recreates the acoustic environment of a modern church with a high pointed dome and columns along the sides. This interior produces a very few primary reflections. CONCERT HALL In this program, the center seems even more deeply behind the front speaker pair, creating an expansive, large hall ambience. ON/OFF Whenever pressed, this switches on/off the built-in digital sound field processor (DSP). When the DSP is on, a program name illuminates in the display and sound output is from the front, rear and (or) center speakers. Conversely, no illumination of program name and no output from the rear and center speakers show that the DSP is off. 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. Additionally licensed under one or more of the following patents: U.S. number 3,950,590; Canadian numbers 1,004,603 and 1,037,877. “Dolby”, “Pro Logic”, and the double-D symbol are trademarks of Dolby Laboratories Licensing Corporation. 20  To play a source with the digital sound field processor Illustrations: RX-V1070 Parts in shaded areas ( ) are not present on RX-V870. 2 3 1 2 Follow step 1–6 shown in “OPERATIONS” on page 15. Select the desired program that is suitable for the source. PRO LOGIC The corresponding indicator will illuminate. 3 If desired, adjust the delay time and the output level of each speaker. (For details, refer to the corresponding descriptions on page 22–23.) Notes ● If you prefer to cancel the selected program, press the ON/OFF switch. The sound will be the normal 2-channel stereo without surround sound effect. ● In the ROCK CONCERT, JAZZ CLUB, CHURCH 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, TREBLE controls or BASS EXTENSION switch, the relationship between the center and rear channels may produce an unnatural effect. 21  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. ● 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 1. PRO LOGIC: from 15 to 30 milliseconds (Preset value: 20 milliseconds) 2. ENHANCED: from 15 to 30 milliseconds (Preset value: 20 milliseconds) 3. 70 mm MOVIE from 15 to 30 milliseconds THEATER: (Preset value: 10 milliseconds) 4. TV THEATER: from 1 to 50 milliseconds (Preset value: 10 milliseconds) 5. ROCK CONCERT: from 1 to 50 milliseconds (Preset value: 15 milliseconds) 6. JAZZ CLUB: from 1 to 50 milliseconds (Preset value: 11 milliseconds) 7. CHURCH: from 1 to 50 milliseconds (Preset value: 40 milliseconds) 8. CONCERT HALL: from 1 to 50 milliseconds (Preset value: 30 milliseconds) 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 ROCK CONCERT, JAZZ CLUB, CHURCH 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 all the digital sound field programs except the above-mentioned ones. ● If a digital sound field program is not used, the CENTER 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 12. CENTER LEVEL C Illuminates. Adjustable. 22  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 12. ● 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. REAR LEVEL R Illuminates. ENGLISH Adjustment of the REAR LEVEL 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. 23  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. Goes off. 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.

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 “learn” its signals. To Learn a New Function 1 Set to the “LEARN” position. 2 Press a key on this unit where a new function will be learned. This unit Other remote control transmitter About 5–10 cm (2–4 in.) 3 Press and hold the key (on the other remote control transmitter) where the desired new function is. 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 25.) These keys have no preset functions and are used only for learning other remote control transmitter’s functions. When the TRANSMIT/LEARN indicator stops illuminating, the learning is finished. 4 5 Repeat step 2–3 until all desired functions are successfully learned. Set to the “USER” position. Try operating your components. YPC-USER-LEARN switch (Refer to page 25.) 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 25.) Press this button to “reset” the internal microcomputer which controls remote control operations.
