Status Monitor
This indicator lights in green when the power is on. The 3547 has built-in
protection circuitry. If, for some reason, this protection circuit is activated,
the indicator turns orange. If this happens, turn the system off, find the cause
of the problem and remedy the situation. This includes checking all your
connections and wiring. If the indicator remains orange when the system is
turned on, consult your authorized Alpine dealer.
NOTE:
The indicator will illuminate in orange for a few seconds when the
power is turned on as the turn on muting circuit is activated. This is normal.
