designed to provide reasonable protection against harmful interference in
a residential installation. This equipment may cause harmful interference to
radio communications, if it is not installed and used in accordance with the
instructions. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio
or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more
of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Cleaning the unit
If the front panel gets dirty, turn off the power and wipe the panel with a dry
silicon cloth or soft cloth.
CAUTION
Do not wipe the panel with a hard cloth or a cloth dampened by volatile
solvents such as paint thinner and alcohol. They can scratch the surface of the
panel and/or cause the indicator letters to peel off.
To prevent battery rise
When the unit is used in the ACC ON position without turning the engine ON, it
depletes the battery. Use it after starting the engine.
Protection function
The protection function is activated in the following situations:
This unit is equipped with a protection function for protecting this unit and your
speakers from various accidents or problems that can occur.
When the protection function is triggered, the PROTECTION indicator lights and
the amplifier stops operating.
• When a speaker wire may be short-circuited.
• When a speaker output contacts ground.
• When the unit malfunctions and a DC signal is sent to the speaker output.
Wiring
• Take the battery wire for this unit directly from the battery. If it’s connected to
the vehicle’s wiring harness, it can cause blown fuses etc.
• If a buzzing noise is heard from the speakers when the engine is running,
connect a line noise filter (optional) to each of the battery wire.
• Do not allow the wire to directly contact the edge of the iron plate by using
Grommets.
• Connect the ground wire to a metal part of the car chassis that acts as an
electrical ground passing electricity to the battery‘s negative · terminal. Do
not turn the power on if the ground wire is not connected.
• Be sure to install a protective fuse in the power cord near the battery. The
protective fuse should be the same capacity as the unit’s fuse capacity or
somewhat larger.
• For the power cord and ground, use a vehicle type (fireproof ) power wring
cord with a current capacity greater than the unit’s fuse capacity. (Use a power
wiring cord with the range of 14 mm (AWG 6) to 21 mm (AWG 4).
• When more than one power amplifier are going to be used, use a power
supply wiring wire and protective fuse of greater current-handling capacity
than the total maximum current drawn by each amplifier.
Speaker Selection
• The rated input power of the speakers that are going to be connected should
be greater than the maximum output power (in Watts) of the amplifier. Use of
speakers having input power ratings that are less than the output power of
the amplifier will cause smoke to be emitted as well as damage.
• Use speakers that have an impedance of 2 or greater. When more than one
set of speakers are going to be used, calculate the combined impedance of
the speakers and then connect suitable speakers to the amplifier.
