speakers)

2 Safety Notes
The unit corresponds to the directive 89/336/EEC for
electromagnetic compatibility.
When connecting the car HiFi booster to the car bat-
tery, be especially careful. In case of short circuits
there may be very dangerously high currents.
Therefore, prior to the connection it is essential to
screw off the negative terminal of the car battery.
The booster 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 booster can become very hot.
Therefore, do not place any objects sensitive to heat
close to the booster and do not touch it while in
operation.
For cleaning only use a dry, soft cloth, by no means
chemicals or water.
If the booster is used for purposes other than
originally intended, if it is not correctly operated or
connected or not repaired in an expert way, no liabil-
ity can be taken over for any possible damage.
If the unit is to be put out of operation definitively, it
must be disposed of in a local recycling plant.
