6. MUTE LEVEL ADJUSTMENT (For qualified service personnel only)
When the Priority control input is activated, the Priority input mutes the Program input by a preset level, which
can be adjusted with the Mute level control inside the unit.
This work should only be performed by a qualified professional
electrician. If users open the unit case or modify the unit, this may
cause fire or electric shock.
WARNING
Step 1. Unscrew the upper case to remove it.
Step 2. Apply different signals to the Priority input
and Program input.
Step 3. Short the Priority control input terminal.
Step 4. While hearing sound, adjust the mute level
control for an appropriate mute level by
turning it clockwise or counterclockwise with
a standard screw driver.
Step 5. Replace the upper case.
[Adjustment procedure]
This adjustment is made under the condition that the unit's power is on and speakers are connected to the
unit.
For safety, be sure to disconnect the AC power from the unit only before opening and replacing the upper
case (Steps 1 and 5 below). In addition, never touch any component other than the Mute level control.
