Set your PIN Code by entering a four-digit number, then pressing the [ENTER] button. Once you set your PIN Code, you will be prompted with the PIN Code input screen if you try to temporarily release the panel lock or initialize internal memory. Partial Lock: Only the following operations are available from the amplifier’s front panel: • Using the [MUTE] button • Controlling attenuation • Recalling library settings for a Speaker Processor component in the SIGNAL PATH screen. Assigning 0000 (default value) to the PIN Code will nullify the code setting. NOTE NOTE • In Amp Editor, Partial Lock has also been added as an option for the Panel parameter (accessed by selecting Utility  Setup  Front Panel Operation  Panel). • Even if the MUTE key or Att. Dial setting is locked in Amp Editor, you will still be able to use the [MUTE] button or adjust attenuation. PIN Code added to Front Panel Operation A PIN Code setting (Personal Identification Number Code) has been added to the Front Panel Operation page of the UTILITY screen. • Initializing User Data in internal memory will initialize the PIN Code and set it to 0000. • To temporarily disable panel lock, simultaneously hold down the [HOME] button and [EXIT] button for three seconds or longer. • While holding down the [HOME] button, turn on the power; the Initialize screen will appear.
