Operation Manual

7
Example 2
The set should be automatically switched on and off with the ignition switch
of the car. The radio shall always start in last used mode on the last used
channel.
Attach the red wire to a part of the vehicle electrical system which is
interconnected to the ignition.
Connect the black wire to the negative pole on the battery or the vehicle
body.
Note for all connecting methods:
For EMC reasons, the cable used to connect to the power supply should be no longer
than 3 metres.
If you wish to operate your set at home from the mains supply then please only use
a stabilised power pack with at least 2 amps permanent current-carrying capacity.
Under no circumstances should you use a car battery charger, as these are not
stabilised and during open circuit reach such high voltage levels that your radio set
could be destroyed.
If in base station use it is important to you that the stored stations are kept even after
switching off and on again, then please do not switch the external power supply
power unit off when you switch your set off for a short time. Only use the on/off
switch on the transceiver itself.
Never repair a blown fuse with silver paper or with aluminium foil! If the fuses
keep blowing, then please give your radio set to your servicing dealer to be
repaired or hand it in to Albrecht’s service station.
The maximum allowed voltage variation for this radio is up to 15.6 volts.
Never exceed this voltage under no circumstances! The transmitting stages
for your AE 4200 R are electronically stabilised, and therefore it is impossible
to increase output by means of excessive supply voltage. Such attempts may
lead to serious damage to the radio set but will never increase output power!
Antenna connection
Connect your CB antenna to the ANT socket on the rear side of your ALBRECHT AE
4200 R. Most CB antennas must be tuned to best radiation during installation to give
highest effective communication range. CB specialists do that job with a standing
wave meter to check and adjust the aerial. Tune the antenna to the best standing
wave ratio (SWR) on an intermediate channel e.g. using Channel 1 in 80/12 mode
(26.965 MHz) or Channel 20 in all other modes.
On this channel you should obtain a SWR of approx. 1.5 or less. If the SWR
deteriorates on the highest (Channel 40) and lowest (Channel 41) channels up to a
value of 2.5, then your aerial is still acceptable. SWR above 3 is too bad for good
