Radio Installation

You can operate your AE 6790 in the car or as a base station at home. For installation as a mobile
station in the car a mobile holder and a variety of installation materials are included. Do not install
the device in direct sunlight, since the increased temperature can shorten the lifecycle of the
device. Do not install in close proximity to a heater. Install the device in such way that it is not
subjected to major vibration.
Install the mobile holder with the included self-tapping screws on dashboard, chassis tunnel or in
other suitable location. Do not install the device in areas where it can cause injuries due to
accident (observe sufficient legroom). Ensure not to damage existing cables during installation!
Slide the radio into the
mobile holder. Fix the device
with the large knurled screws
(use the included plastic
washers!) in the desired view
angle. Detach the front panel
(loosen 2 screws at the
bottom) if installation of the
complete unit is not possible
and install the radio separate
from the control panel. Install
the microphone bracket with
the included screws in an
easy to reach location.
For detached installation use the included approx. 2m long 9-pin Sub-D cable.

The installation material includes the two
screws for the plug if not already attached to
the cable.

Power Supply

Power supply via the 2-pole plug-in cable, which is equipped with in-line fuse holder. Operate the
radio in vehicles (12V) or as base station via suitable 12V power adaptor (at least 2A, stabilized).

Vehicle Power Connection

Connect the red power cable to the positive terminal (i.e. a point within the vehicle wiring with
12V supply power) and the black cable to the negative terminal.
We strongly recommend connecting the radio directly to the battery. Generally direct connection
supplies the most stable operating voltage and optimum protection against interferences during
reception and transmitter modulation.
Modern vehicle wiring is so complex that connecting to other points (such as car radio terminals or
cigar lighter) can lead to interferences. These can be heard as "singing" or crackling during
reception, in some persistent cases also during transmission as "alternator noise".
If you cannot connect directly to the battery, as recommended, try the best possible connecting
point before final installation. Start the engine to check if the selected connection causes reception
