Safety Precautions

People with pacemakers are recommended as a precaution to consult their doctor
before operating the CB radio. Not all types of pacemakers are sufficiently protected
from radiation from a nearby transmitter, so do not assume it is safe to start
operation without checking! Please remember that you are in the immediate vicinity
of a transmitting aerial, particularly when used as a mobile. If your doctor, or the
manufacturer of the pacemaker, has recommended keeping a certain safe distance
from the aerial, then please follow their instructions!
Do not transmit without connecting the aerial and never touch the aerial during
transmission!
Please also take road safety into account! CB Radio (even when only receiving,
particularly when volume is turned up) can divert your attention from the road! Road
safety is of course to be given priority! Therefore only use your ALBRECHT AE 4090
when the traffic situation enables it to be used safely.

Installation of the radio

You can either operate your ALBRECHT AE 4090 in the car or at home as a base
station. For installation as a mobile station in the car, a mobile mount device is
enclosed. Mount the set in such a way that it is not exposed to direct sunlight if
possible, as this would lead to an increase in the temperature and can decrease the
(set’s) working life. The set should also not be installed near a heater. Mount the set
in such a way that it is exposed to as little vibration as possible.
The mobile fixing device should be attached to the dashboard, the tunnel slot or to
any other suitable place using the enclosed tapping screws. Do not install the set in
a place where it could cause injuries in the case of an accident (be careful to ensure
