■ SELF-DIAGNOSTIC FUNCTION /
● Protection Information Display
When the power to this unit is turned on and the power
indicator is flashing, the normal operation is not avail-
able because the protection function is at work.
In that case, the protection information can be dis-
played by following procedures. However, the power
supply relay (RY1 of FUNCTION P.C.B.) does not turn
on.
• Operation procedures
Turn the “BALANCE” knob counterclockwise fully
and then while pressing down the “AUDIO MUTE”
switch, set the “POWER ON/OFF” switch to the
ON position.
