Caution in Case of High Volumes
With the motor switched off, the car HiFi system
should not be in operation at high volume for a
longer period of time. The car battery will quickly be
discharged, and then it may not be capable any
more of supplying sufficient energy for starting the
car.
CAUTION Never adjust the volume very high.
Extremely high volumes may dam-
age your hearing. The human ear
gets accustomed to high volumes
which do not seem to be so high any
more after some time. Therefore, do not further
increase a high volume which has once been
adjusted after getting used to it.
While driving in the car, signal sounds, e. g. by an
ambulance, must not be drowned by the volume
of the car HiFi system which has been adjusted
too high.
If the unit is to be put out of operation
definitively, take it to a local recycling plant
for a disposal which is not harmful to the
environment.
WARNING When connecting the car HiFi power
amplifier to the car battery, be espe-
cially careful. In case of short circuits
there may be dangerously high cur-
rents. Therefore, prior to the connec-
tion, it is indispensable to screw off the
negative terminal of the car battery.
The power amplifier must be mounted to a
mechanically stable place in the car. It must be
skilfully fixed so that it does not get loose and turn
into a dangerous projectile.
During operation the unit may become very hot.
Therefore, do not place any objects sensitive to
heat close to it and do not touch the power ampli-
fier while in operation.
