• Use ungrounded speaker only.
• The maximum speaker input should be 50 W or more. (If used with the optional
power amplifier, the speaker input should be higher than the maximum amplifier
output.)

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

apart) from the antenna and antenna extension cord.
• Never connect the speaker cord to
the body of the car.

system having a common earth
lead.

speaker to one set of speaker

connecting the unit directly without a fuse, could cause fire or damage to the unit.
If the fuse replacement fails, consult your nearest Panasonic Service center.
Maintenance
Your product is designed and manufactured to ensure the minimum of maintenance. Use a soft cloth for
routine exterior cleaning. Never use benzine, thinner, or other solvents.
