BFC (Beat Frequency Control) Switch

If you hear a beat while listening to an AM broadcast with your car stereo, change the BFC switch using a small standard tip screwdriver.

Connecting the Unit

CAUTION

Disconnect the negative (–) terminal of the battery to avoid the risk of short-circuit and damage to the unit.

Secure the wiring with cable clamps or adhesive tape. To protect the wiring, wrap adhesive tape around it where they lie against metal parts.

Do not route wires where they will get hot, for example where the heater will blow over them. If the insulation heats up, it may become damaged, resulting in a short-circuit through the vehicle body.

Make sure that wires will not interfere with mov- ing parts of the vehicle, such as the gearshift, handbrake or seat sliding mechanism.

Do not shorten any wires. Otherwise the protec- tion circuit may fail to work when it should.

Never feed power to other equipment by cutting the insulation of the power supply wire to tap from the wire. The current capacity of the wire will be exceeded, causing overheating.

Never replace the fuse with one of greater value or rating than the original fuse. Use of an improp- er fuse could result in overheating and smoke and could cause damage to the product and injury including burns.

Connecting the Power Terminal

Always use the special red battery and ground wire [RD-223], which is sold separately. Connect the battery wire directly to the car battery positive terminal (+) and the ground wire to the car body.

1.Pass the battery wire from the engine compartment to the interior of the vehicle.

After making all other connections to the amplifier, connect the battery wire terminal of the amplifier to the positive (+) terminal of the battery.

WARNING

Failure to securely fasten the battery wire to the ter- minal using the terminal screws could cause the ter- minal area to overheat and could result in damage and injury including minor burns.

• Use pliers, etc., to crimp lugs to wires.

3. Connect the speaker wires to the

distorts when the volume is turned up, turn the gain control counter- clockwise.

When using with an RCA equipped car stereo (standard output of 500 mV), set to the NORMAL position. When using with an RCA equipped Pioneer car stereo with max. output of 4 V or more, adjust level to match the car stereo output level.

If you hear too much noise when using the speaker input terminals, turn the gain control counter-clockwise.

To prevent damage and/or injury

Do not ground the speaker wire directly or con- nect a negative (–) lead wire for several speakers.

This unit is for vehicles with a 12-volt battery and negative grounding. Before installing it in a recre- ational vehicle, truck or bus, check the battery voltage.

If the car stereo is kept on for a long time while the engine is at rest or idling, the battery may go dead. Turn the car stereo off when the engine is at rest or idling.

If the system remote control wire of the amplifier is connected to the power terminal through the ignition switch (12 V DC), the amplifier will always be on when the ignition is on— regardless of whether the car stereo is on or off. Because of this, the battery could go dead if the engine is at rest or idling.

Connect a subwoofer with a 290 W or larger nom- inal input and an impedance between 2 and 8 ohms to the amplifier. If the nominal input and impedance are out of the above ranges, the sub- woofer may catch fire, emit smoke or become damaged.

Install and route the separately sold battery wire as far away as possible from the speaker wires. Install and route the separately sold battery wire, ground wire, speaker wires and the amplifier as far away as possible from the antenna, antenna cable and tuner.

Cords for this product and those for other prod- ucts may be different colors even if they have the same function. When connecting this product to another product, refer to the supplied Installation manuals of both products and connect cords that have the same function.
