POWER/PROTECT indicator

• If your car is parked in direct sunlight

with the windows closed the
temperature inside it rises
considerably.  At such times, allow the
humidity level inside the car to drop
before using the system.

• The protection circuit inside the

amplifier will operate under the
following circumstances in order to
protect the output transistor and the
speakers:
– when the level of temperature

inside the amplifier has become
excessive

– when an abnormality has occurred

and a DC voltage has been
generated

– when an output terminal has been

short circuited

At this time the color of the POWER/
PROTECT indicator will change from
green to red and sound will no longer
be audible from the speakers.  If this
happens, turn off the connected
equipment immediately and
investigate the cause of the
malfunction.  When you think that
overheating is the cause, wait until the
unit cools down before using.

• Do not use the unit on a weak battery

as it depends on the condition of the
battery for optimal performance.

• For safety reasons, keep the volume at

a level that allows you to hear sounds
outside the vehicle when driving.

• Do not obstruct the ventilation holes

provided for the fan.

Fan

When a short circuit occurs or the unit is
damaged, a fuse blows preventing
excessive current from flowing into the
unit.  If a fuse blows, check the power
source and ground lead connections and
replace the fuse.  If a fuse blows again
soon after it has been replaced, consult
your nearest Sony dealer.

• Never use a fuse with an amperage

other than what is specified, as this
could result in damage to the unit.
