Installation
Select the mounting location so that road safety is not affected by the device, or
additional risk of injury in an accident arises. Check that the display can be seen, and
the controls can easily accessed.
Power supply
Connect the cigarette lighter power cable to the proper plug of your vehicle. Be
sure your car has a power supply of 12V and not 24V.
Antenna connection
Connect the CB antenna to the ANT socket on the back of your M-MINI. The
antenna must be tuned to the CB radio band. For this use a SWR meter. For a
good radio range, the SWR should not exceed a value of 2. A high SWR also points
to defects in antenna, cable, or a short circuit in the antenna line. Never transmit
without connected antenna!
Note: The radio antenna is to be mounted from other antennas and interference sources
as much as possible. CB antennas must be mounted usually in the vehicule highest part
on a metal surfaces. A sufficiently large metal surface is essential for the function of the
antenna. For installation on a fiberglass cabs or plastic wind deflectors, special ground
less antennas can be used.
