CONTROLS

KS-AX3004

KS-AX3002

ÅPOWER indicator

The green lamp lights while the unit is turned on.

ıCROSSOVER filter switch

OFF: Normally set to this position. The switch is preset to this position when the unit is shipped.

LPF: Set to this position when you want to turn on the LPF (Low-Pass Filter) switch. The Low-Pass Filter transmits frequencies lower than 80 Hz.

HPF: Set to this position when you want to turn on the HPF (High-Pass Filter) switch. The High-Pass Filter transmits frequencies higher than 150 Hz.

ÇInput LEVEL controller

The input level can be adjusted with this control when this unit is connected to other source equipment. Adjust the level while listening to the sound. This control is preset to MIN when the unit is shipped.

TROUBLESHOOTING

For more details, consult your “JVC IN-CAR ENTERTAINMENT” car audio dealer.

The POWER indicator does not light.

•Change the fuses if the current one is blown.

•Connect the ground lead securely to a metal part of the car.

•Turn on the equipment connected to this unit.

•Confirm the battery voltage (11 V to 16 V).

•Use a relay if your system employs too many amplifiers.

•Leave the unit turned off to cool it down if it heats up abnormally.

No sound is heard.

•Confirm the connections for the power supply (see "POWER SUPPLY" on page 1).

•Connect the RCA pin cords to the INPUT jacks, or the speaker input connector to the HIGH INPUT terminal.

•Confirm the speaker wirings and the position of the CROSSOVER filter switch (See “SPEAKER CONNECTIONS” on page 2).

Alternator noise is heard.

•Keep the leads of the POWER terminals away from the RCA pin cords.

•Keep the RCA pin cords away from other electrical cables in the car.

•Connect the ground lead securely to a metal part of the car.

•Make sure the speaker negative leads do not touch the car chassis.

•Connect a bypass capacitor across the accessory switches (horn, fan, etc.).

Noise is made when you connect the unit to an AM (MW/LW) tuner.

• Move all the leads of this unit away from the antenna (aerial) lead.
