Installation of your Oricom Radio
The radio’s positive (red) lead should connect to an accessory point in
the vehicle’s fuse box via the 2 Amp fuse.
Antenna information
The antenna (not supplied) is of critical importance, to maximize your
output power and receiver senstivity.
A poorly installed, inferior quality antenna or one not designed for the
correct frequency band will give poor performance. You should only
purchase an antenna designed for the 477MHz frequency band.
Antenna installation
1. Connect the antenna to the rear antenna socket using a PL259 coaxial
connector (not supplied).
2. To obtain maximum performance from the radio, select a high quality
antenna and mount it in a good location. Never press the PTT or
CALL button before connecting the antenna to the radio.
Optional External Speaker
Depending on the installation it may be necessary to use an external
speaker (not supplied) to give improved volume and clarity. This can be
plugged into the EXT –SPK socket on the rear of the unit.
