Please read before installing or operating your Oricom radio

The operation of your UHF radio in Australia and New Zealand is subject to conditions in the following licenses: In Australia, the ACMA Radiocommunications(Citizen Band Radio Stations) and in New Zealand by MED the General User Radio License for Citizen Band Radio.

When a new narrowband radio receives a transmission from an older wideband radio the speech may sound loud and distorted – simply adjust your radio volume for the best listening performance. When an older wideband radio receives a signal from a new narrowband radio the speech may sound quieter – simply adjust your radio volume for best listening performance. When operating a narrowband radio or Channel 41 – 80 interference is possible from wideband radios transmitting on high power or on adjacent frequency. The issues described above are not a fault of the radio but a consequence of mixed-use of wideband and narrowband radios.

This unit complies with all relevant Australian and New Zealand approval requirements AS/NZS 4365:2011

Warnings and Safety Information

Potentially Explosive AtmosphereTurn your radio OFF when in any area with a potentially explosive atmosphere. Sparks in such areas could cause an explosion or fire resulting in injury or even death.NOTE: Areas with potentially explosive atmospheres are often, but not always clearly marked. They include fueling areas such as below deck on boats; fuel or chemical transfer or storage facilities; areas where the air contains chemicals or particles, such as grain, dust, or metal powders; and any other area where you would normally be advised to turn off your vehicle engine.Blasting Caps and AreasTo avoid possible interference with blasting operations, turn your radio OFF near electrical blasting caps or in a “blasting area” or in areas posted: “Turn off two-way radios.” Obey all signs and instructions.Electromagnetic Interference/CompatibilityNearly every electronic device is susceptible to electromagnetic interference (EMI). To avoid the possibility of electromagnetic interference and/or compatibility conflicts, turn off your radio in any location where posted notices instruct you to do so such as health care facilities.

This radio is designed for operation on a 12 Volt battery system. It should not be connected directly to a 24 Volt system. When installing your radio in your vehicle, check that during installation you do not damage any wiring or vehicle components that may be hidden around the mounting position. Ensure the installation does not interfere with the operation of the vehicle and meets all regulatory and safety retirements for accessories fitted to your vehicle. For optimum performance, your radio needs to be installed correctly. If you are unsure about how to install your radio, we suggest you have your radio professionally installed by a UHF specialist or Auto electrician. When installing the radio, avoid mounting it close to heaters or air conditioners. Never press the PTT button before connecting the antenna to the radio.

Installation of Your Oricom Radio

Wiring MethodsThere are two possible wiring configurations for connecting to the vehicle’s power supply.A. Radio stays ON when the ignition is switched OFFConnect 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 switchConnect the radio’s negative (black) lead to the vehicle’s chassis, or directly to the battery’s negative terminal. The radio positive (red) lead should connect to an accessory point in the vehicle’s fuse box via the 3 Amp fuse.

Antenna informationThe antenna (not supplied) is of critical importance to maximize 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 pur chase an antenna designed for the 477MHz frequency band.Antenna installationTo 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 speakerIf 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.

Note that additional channels 41-48 and71-78 are also available for repeater operation to supplement channels 1-8 and-31-38 respectively as approved by the ACMA CBRS Class Licence in Australia and the MED GURL in New Zealand. In addition, any designated repeater channel may be used for simplex operation in areas where it is not used for repeater operation.† Speech telephony shall be inhibited on these channels.‡ At the time of production Channels 61, 62, and 63 are guard channels and are not available for use. Channel 5 and 35 (paired for Duplex repeaters) are reserved as emergency channels and should be used only in an emergency.CTCSS and DCS will not operate on these channels.A list of currently authorized channels can be obtained from the ACMA website in Australia and the MED website in New Zealand. Channel 11 is a calling channel generally used to call others and channel 40 is the customary road vehicle channel. Once contact is established on the calling channel, both stations should move to another unused “SIMPLEX”channel to allow others to use the calling channel. Channels 22 and 23 are for Telemetry and Telecommand use, voice communications are not allowed on these channels by law.Channel 9 and above are the best choices for general use in Simplex mode.
