Albrecht AE 6890 Bedienungsanleitung Seite 26

Connect up the red to the positive pole on the vehicle battery (or elsewhere in the
vehicle's electrical system with permanent plus) or to a 12 volt power unit.
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. (Not all body ground positions are good for radio
communication- in most cases the battery Minus is the best connecting position)
Example 2
The set should be automatically be switched on and off with the ignition switch of the car.
Due to it's EEPROM memory the radio will also store the last channel and country setting
used before, regardless how long it had been discontinued from power.
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: if in complex installation it is not possible to suppress all noise and interference
coming via DC installation, our optional DC noise filter Nr. 70600 may help. The filter can
be installed into the DC power line to the CB radio.
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 supply with at least 2 amps permanent current 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 may be important to keep the last setting 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! Use only original fuses
for 5 A max. If the fuses keep blowing, then please give your radio set to your servicing
dealer to be repaired or hand it in to an authorized service station.
The maximum allowed voltage variation for this radio is from 10.8 volts up to 15.6 volts.
Never exceed the upper voltage limit under no circumstances! The transmitting stages for
your AE 6890 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!
Instructions especially for truckers and motor home users
The permitted operating-voltage of the radio may vary from 10.8 to 15.6 V, so between
these to values the performance data of the radio do not change. The transmitting levels of
your AE 6890 are electronically stabilised. So an increasing of the performance by using
an excessive operating-voltage is impossible. With such methods you only risk damaging
your radio, but not an increased performance! Truckers should take care of never
connecting their radio directly to 24 Volt. At 24 volt you need a suitable voltage converter
