1. Turn the unit off.
2. Remove all wires attached to the power
antenna lead. Check each wire for a
possible short to ground using an ohm
meter.
3. Turn the unit back on.
4. Reconnect each amplifier remote wire
to the power antenna lead one by one.
If the amplifiers turn off before all wires
are attached, use an external relay to
provide remote-on voltage (excessive
current required).
Wipe the dirt off with a soft cloth moistened
with cleaning alcohol.

also be restored by turning the power
off and on again. (Speaker volume is
reduced automatically when the speaker
protection circuit operates).

service department.
