Operating Procedures
For your driving safety, keep the volume level low enough to be aware of road and traffic conditions.
Precautions:
m This unit is designed to be used with a Panasonic cassette/CD player model.
m 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.
a 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.
E 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 @ to the left or right until the output from
each amplifier is balanced by using the Level Adjust Volume as shown in
the illustration.
E Bass Level Adjustment :
The bass output level from speakers can be increased by using the Bass
Level Adjust Volume, You can adjust the middle frequency 60 Hz within
the range of O dB to 14 dB. For some speakers, the sound may be dis-
torted because of the excessive data input for them. In that case, turn
down the bass level until the distortion stops.
