Speaker Connections

Cautions:
1. Use ungrounded speakers only.
2. The speakers to be used with this unit should be able to handle more than 40 W of audio power. If an

optional amplifier is used, the speakers should be able to handle the maximum output power of the
amplifier. Use of speakers with small input ratings can cause damage to the speakers.

3. The speaker impedance should be 4 - 8 

. If the impedance is too large or too small, it affects the output

and may cause damage to the speakers or this unit.

4. Do not use 3-wire type speaker system having a common earth lead. Never connect the speaker cord to

the body of the car. This unit uses the BTCL circuit, so each speaker should be connected separately
using parallel vinyl insulated cords.

5. The speaker cords and the power amplifier unit should be kept away (about 30 cm apart) from the anten-

na and antenna extension cord.

6. Follow the connection diagram below carefully. Failure to do so may cause damage to both unit and

speakers.

Fuse

Use fuses of the same specified rating (15 A). Using different substitutes or fuses with higher ratings, or con-
necting the unit directly without a fuse, could cause fire or damage to the unit.
If the replacement fuse fails, contact your nearest authorized Panasonic Service Center.

Maintenance

Your product is designed and manufactured to ensure the minimum of maintenance. Use a soft cloth for rou-
tine exterior cleaning. Never use benzine, thinner, or other solvents.

¡

Unit will be damaged if speakers (Front, Rear) are not connected properly.

¡

Do not connect more than one speaker to one set of speaker leads.
