Precaution - Orion HCCA3000.1DSPLX Manual

CHARGING SYSTEM:
Audio systems with a single amplif ier can be supplied by most
vehicles electrical systems. Systems with multiple amplif iers or a
amplif ier that draws extensive amount of current require a higher
capacity, battery, alternator or the use of a storage capacitor. We
strongly recommend researching the capabilities of the charging
system of the vehicle.
This unit is designed for 12VDC operation only. Use speakers with an
impedance of 2 or 4-Ohms (1-4 0hms Class-D amps)
Avoid installing the unit where:
• It would be subject to high temperatures, such as from direct sun
light or hot air from the heater.
• It would be exposed to rain or moisture.
• It would be subject to dust or dirt.
• If your car is parked in direct sunlight and there is a considerable
rise in temperature inside the car, allow the unit to cool off before
operation.
• When installing the unit horizontally, be sure not to cover the heatsink
fins with the floor carpet.
• If this unit is placed too close to the car radio, interference may occur.
In this case, separate the amplifier from the car radio.
• This power amplifier employs a protection circuit to protect the
transistors and speakers if the amplifier malfunctions. Do not attempt
to test the protection circuits by covering the heatsink or connecting
improper loads.
• Do not use the unit with a weak auto battery as its optimum
performance depends on a normal battery supply voltage.
• For safety reasons, keep the volume of your car audio system
moderate so that you can still hear your surroundings.
If the fuse blows, check the power connection and replace the fuse.
If the fuse blows again after replacing it, there may be an internal
malfunction. In this case, consult your dealer.
PROTECTION CIRCUIT:
This amplif ier is provided with a protection circuit which operates in
the following cases when:
The unit is overheated.
The speaker terminals are short circuited.
