Operating Instructions
UHF350DR 80 Channel UHF Citizen Band Radio

When a 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

Safety Information and Warnings
WARNING
Potentially Explosive Atmospheres
Turn your radio OFF when in any area with a potentially
explosive atmosphere. Sparks in such areas could cause an
explosion or re resulting in injury or even death.
NOTE: Areas with potentially explosive atmospheres are often,
but not always clearly marked. They include fuelling 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 Areas
To 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/Compatibility
Nearly every electronic device is susceptible to electromagnetic
interference (EMI). To avoid the possibility of electromagnetic
interference and/or compatibility conicts, turn off your radio
in any location where posted notices instruct you to do so such
as health care facilities.

Installation of your Oricom Radio
CAUTION
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 requirements for
accessories tted 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 or CALL button before connecting the antenna to the
radio.
Wiring Methods
There are two possible wiring congurations 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 radio’s positive (red) lead should connect to an accessory point in
the vehicle’s fuse box via the 3 Amp fuse.

Installation of your Oricom Radio
Antenna information
The 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
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.
3. For best performance always mount your antenna as high as possible
and away from all other antennas or poles.
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.

104 DCS tone).
To achieve this, all radios in your group must have the same channels in
A, B, C memory (group memory channels) and use the same Subcode
(38 CTCSS and 104 DCS tone).

15
Operations
By scanning only group channels, radios in the network will be able

Duplex
General
Your radio has a Repeater Access function to allow use of local repeater
stations (if available in your area). Repeaters are shared radio systems
installed by interested parties (clubs, local business etc.) that receive
transmissions on specic channels and re-transmit (or repeat) the
received signal to another channel.
Channel 2
Channel 32
Channel 2
Channel 32
Repeater Station
The Repeater Access function can be set (from channel 1 to 8 and 41
- 48) used by local repeater stations. When activated, your radio will
receive the Repeater on its specic channel (all repeater outputs are on
channel 1 to 8 and 41 to 48) but transmit to the repeater channel 31
through 38 and 71 to 78.
(Factory default is set to On for all repeater channels).
e.g.
CH01 on Duplex mode will receive on CH01 but transmit on CH31.
CH02 on Duplex mode will receive on CH02 but transmit on CH32.
If you transmit on CH01 duplex mode, you are actually transmitting on
CH31.
The repeater station receives your signal on CH31 and retransmits on
CH01.
Your UHF radio allows you to pre-select Duplex operation individually
on each channel.
