To turn on/off the key-touch tone
You can deactivate the key-touch tone if you do not want it to beep each time you press a
button. When shipped from the factory, the key-touch tone is activated.
• BEEP ON: Activates the key-touch tone.
• BEEP OFF: Deactivates the key-touch tone.
To turn on/off the power amplifier switch
You can switch off the built-in amplifier and send the audio signals only to the external
amplifier(s) to get clear sounds and to prevent internal heat buildup inside this unit. When
shipped from the factory, the power amplifier switch is turned on so that the built-in amplifier
works.
• P. AMP ON:
• P. AMP OFF:
To adjust the display contrast level
You can adjust the display contrast level among 01 (dark) to 10 (bright). When shipped from
the factory, the display contrast level is set at level 05.
To select the scroll mode
You can select the scroll mode for the disc information if it consists of more than 12 characters.
When shipped from the factory, Auto Scroll mode is set to "SCROLL ONCE."
• SCROLL ONCE: Scrolls only once.
• SCROLL AUTO: Repeats the scroll (in 5-second intervals).
• SCROLL OFF:
Note:
Even if the scroll mode is set to "SCROLL OFF," you can scroll the display by pressing DISP for
more than 1 second.
To adjust the line input level
Adjust the line input level properly when an external component is connected to the LINE IN
plugs. When shipped from the factory, the line input level is set at level 00.
If the input level of the connected component is not high enough, increase the input level
properly. Without adjusting the line input level, you may be surprised at a loud sound when
you change from the external component to another source.
