In order to prevent interference to the vehicle electronics from transmission in the
vehicle, please make sure to take any mounting instructions from the vehicle
manufacturer for radios and antennas into account.
Power supply
Your AE 4190 receives power from the fixed mounted 2 wire power cable.
The cable has a looped-in fuse in a plastic holder.
You can choose from two methods when connecting to the power supply (red and black):
Example 1
The channel and mode last used should be maintained after switching off; the
set should be able to be switched on and off at any time using the POWER
on/off switch.
Connect up the red coloured wire to the positive pole on the vehicle battery (or
elsewhere in the vehicle’s electrical system with permanent plus) or to a 12 volt
external power supply 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.
Example 2
The set should be automatically switched on and off with the ignition. There is no
last used mode and channel memory and the radio always re-starts on Channel
1 in FM.
Attach the red wire to a part of the vehicle electrical system which is
interconnected to the ignition.
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
stabilized power pack with at least 2 amps permanent current-carrying capacity. Under
no circumstances should you use a car battery charger, as these chargers are not
stabilized and during open circuit reach such high voltage levels that your radio set could
be destroyed.
In any case, please set the country switch on the rear side to the correct country position
before
You connect the DC cable! Do not change country switch position while radio is
still connected to power supply.
If in base station use it is important to you that the last used mode and channel is kept in
memory 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 set itself.
