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.

2CAUTION

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 Power indicator goes OFF 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.

· When the internal temperature is high and unit won't operate.

· When a ground wire of the center unit (cassette receiver, CD receiver, etc.)

or this unit is not connected to a metal part serving as an electrical ground

passing electricity to the battery's negative

- terminal.

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 a diameter of 8 mm2 (AWG 8) or greater.)

· 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 1 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.
