Alpine CDA-7990 manual Blackout Mode On and Off, 23-EN

Blackout Mode On and Off

Turning off the back light of front panel can resist the inference from the noise caused by the back light and provide you a much higher quality sound.

1 Press and hold the B. OUT (Black out) button for at least 3 seconds, the “B-OUT ON” indication appears and disappears. Then the blackout mode starts. The back light turns off with only the

B. OUT indicator ON, and the audio signals bypass the treble and bass circuits. This reduces noise to give a clean, flat response.

To cancel the blackout mode, press and hold the B. OUT (Black out) button for at least 3 seconds. After the “B-OUT OFF” indication appears and disappears, the back light turns on with the

B. OUT indicator OFF.

•If any button on the unit is pressed during the blackout mode, the function will be displayed for 5 seconds to show the operation before returning to Blackout mode.

•The BASS/TREBLE control is bypassed when the display panel lighting is OFF.
