Installation of Your Oricom Radio
Fitting the Controller Speaker Microphone
The controller speaker microphone uses a 6-pin telephone style plug and socket:
1. Position the microphone plug so the plastic flap faces upward, and insert the plug into the socket until it
‘clicks’.
2. Gently press the rubber boot into the hole surrounding the socket so that the slot around the boot fits
neatly inside the rim of the entry hole.
Disconnecting the Controller Speaker Microphone
It is recommended that the Controller Speaker Microphone be left permanently connected to the radio, but if
it must be disconnected, proceed as follows:
1. Lift the rubber boot and the lip of the raised area on the front panel.
2. Ease the rubber boot out of the cable entry hole and slide it along the cable away from the front panel.
3. Identify the plug locking lever, and move the lever towards the plug body. At the same time gently pull the
plug from the socket.
Wiring Methods
There are two possible wiring configurations for connecting to the vehicles power supply.
A. Radio stays ON when the ignition is switched OFF
Connect the radio’s negative (black) lead to the vehicle chassis, or directly to the battery’s negative terminal.
Connect the radio’s positive (red) lead via the 3 Amp fuse to the battery’s positive terminal. Alternatively,
the positive lead could be connected at the fuse box at a point that has DC Power continuously available
(preferably the battery side of the ignition switch) via the 3 Amp fuse.
B. Radio turns OFF with the ignition switch
Connect the radio’s negative (black) lead to the vehicle’s chassis, or directly to the battery’s negative
terminal.
The radios positive (red) lead should connect to an accessory point in the vehicle’s fuse box via the 3 Amp
fuse.
Antenna information
The antenna (not supplied) is of critical importance to maximise your output power and receiver sensitivity.
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
To obtain maximum performance from the radio, select a high quality antenna and mount it in a good
location.
Never press the PTT before connecting an antenna to the radio.
Optional accessories
SPE85
External speaker
If required, you may install an external (8 ohm, Minimum 5W power) speaker
fitted with a 3.5mm plug (not supplied).
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
external speaker (SP) socket on the rear of the unit.
