Removing the Radio
If the main unit is installed in a remote location, you may need
to install an extension speaker inside the cabin. The extension
speaker plugs into the extension speaker socket on the rear
panel of the main unit.
Fitting the Controller Microphone
Plug the 8 pin plug into the socket on the front of the main
unit or alternatively you can use the adapter and extension
cable supplied with the radio. If the main unit is not easily
accessible this adapter will allow you to bring the microphone
socket to a more convenient position
Attach the microphone clip to a convenient location near your
driving position using screws. Slide the bollard on the back of
the microphone into the clip to secure it.
DC POWER CONNECTION
The radio is designed for 13.8 volt DC, negative earth
installations only (i.e. where the negative terminal of the
battery is connected to the chassis or frame of the vehicle).
There are two recommended methods of installation.
Radio remains ON when the ignition switch is OFF
Connect the radio’s negative (black) lead to the vehicle’s
chassis, or if preferred, directly to the battery’s negative
terminal. The radio’s positive (red) lead should be connected
via the 2 amp fuse to the battery’s positive terminal.
Alternatively, the positive lead could be connected into
the fuse box at a point that has +13.8 volts continuously
available (on the battery side of the ignition switch) via the
2 amp fuse.
