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

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 vehicle 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.
