Example 2
The set should be automatically switched on and off with the ignition switch.
Attach the red wire to a part of the vehicle electrical system, which is
interconnected to the ignition.
Connect up the black wire to the negative pole on the vehicle battery or the
power unit or to a well-conductive part of the car body.
An
EEPROM memory
if the radio is not connected to power.
Note for all connecting methods:
For EMC reasons, the cable used to connect to the power supply should be no longer
than 3 metres and have sufficient diameter (at 3 meters length not below 1.5 – 2.5
2
mm ).
If you wish to operate Your set at home from the mains supply then please only use a
stabilized 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
stabilized and during open circuit reach such high voltage levels that Your radio set
could be destroyed.
The stored country code and all memory channels are kept in an EEPROM-memory.
The memory settings of the radio will be in the same condition after You plug out and
plug in the DC cable.
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 5090 XL are electronically stabilized, 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!
In most truck installation a step down DC-DC converter 24 to12 V is used.
Best CB reception quality is only possible with standard linear voltage
reducers. Switching step down converters may radiate interference signals
due to their technology. Even if such converters have valid approval marks,
the CB range is disregarded by the specifications and we cannot assure
interference free reception. If such a converter should be installed in Your
truck, it is recommended to place the antenna as far away as possible from
DC-DC converters and engine management computers.
