PRECAUTIONS
• Use speakers with an impedance of 2-4 Ohms
• Avoid installing unit where:
o It would be subject to high temperatures, such as from direct sunlight or
hot air from the heater.
o It would be exposed to rain or moisture.
o 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.
• 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 heat sink or connection improper loads.
• Do not use the unit with a weak auto battery as its optimum performance depends on
a normal battery supply voltage.
FUSE REPLACEMENT
If the fuse blows, check the power connection and replace the fuse. If the fuse blows again after
replacement, there may be an internal malfunction. In this case, consult your dealer.
WARNING:
Use the specified amperage fuse. Use of a higher amperage fuse may cause serious damage.
PROTECTION CIRCUIT:
This amplifier is provided with a protection circuit which operates in the following cases when the
unit is overheated or the speaker terminals are short circuited.
