Operating Procedures
For your driving safety, keep the voiume level low enough to be aware of road and traffic conditions.
Precautions:
■ This unit is designed to be used with a Panasonic cassette/CD player model.
■ This unit is automatically switched on and off if the power switch of the cassette/CD player is turned on
and off. The power indicator lights up when the cassette/CD player is turned on.
■ Due to its large output, the current consumption of the unit is also large; therefore, the unit should not be
used when the engine is turned off. Otherwise, the battery may deteriorate so that starting of the engine
may become impossible.
■ Level Adjustment:
In some instances, the acoustical output from each speaker may not be
balanced properly depending upon the type of speakers or cassette/CD
player unit to be used. If this occurs, try to adjust the volume level by
turning the level adjust volume
0
and
0
to the left or right until the out¬
put from each amplifier is balanced by using the Level Adjust Volume as
shown in the illustration.

cy 60 Hz within the range of 0 dB to 14 dB. For some speakers, the
sound may be distorted because of the excessive data input for them. In
that case, turn down the bass level until the distortion stops.
