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

There is a Protection function installed in the unit to protect the unit and speakers from various problems. When Protection operates, the indicator informs you of the condition. (Refer to page 5)

■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 5 mm2 (AWG 10) or

 

greater.)

to be used, use a power supply wiring wire and

■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.

•The impedance of the speakers that are going to be connected should be 2Ω or greater (for stereo connections), or 4Ω or greater (for bridged connections). 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.
