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.

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.
