Operating Instructions
UHF305 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 Atmosphere
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 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 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 retirements 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 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 batteries 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 batteries negative terminal.
The radios 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. This radio is tted with a NEW small FME type antenna
connector. If this is not compatible with your existing antenna
connection, please contact Oricom to purchase an adaptor.
(Part Number: 2U0159)
2. To obtain maximum performance from the radio, select a high
quality antenna and mount it in a good location.
Never press the PTT button before connecting the
antenna to the radio.
Optional accessories
If required, you may install an external (8 ohm, min 5W power)
speaker tted 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.

General
Your radio has a Repeater Access function to allow use of
local repeater station (if available in your area). Repeaters are
shared radio systems installed by interested parties (clubs, local
business etc.) that pick transmissions on specic channels and
re-transmit (or repeat) the received signal to another channel.

Channel 32

Channel 32
Repeater Station

18
Operations
The Repeater Access function can be set (from channel 1 to 8
and 41 to 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 to 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 down converts your
signal and retransmits on CH01.
Your transceiver allows you to pre-select Duplex operation
individually on each channel.

CTCSS and DCS Setting
This feature allows you to receive signals only from callers who have
selected the same CTCSS and DCS code. DCS is similar to CTCSS. It
provides 104 extra, digitally coded, squelch codes that follow after the
38 CTCSS codes. CTCSS 1 - 38, followed by DCS 1 - 104.
Scramble
Scramble enables private communications by scrambling the voice
signal. This prevents users without descrambler equipment or a
compatible unit from understanding the conversation.
You can select 5 different scrambler settings in the menu, “S” appears
on the LCD when the scrambler function is turned on.
7 Multi Colour backlight
You can select from 7 different colours for the LCD backlight.
LCD Backlight Brightness
You can reduce the brightness of the LCD backlight to be more
comfortable while driving at night.
Voice Enhancer Equalizer
Choose from 10 different receive audio level settings to provide a
natural voice enhancer for super clarity and performance.
Operations

20
The radio has 10 preset (-5 to 5) voice enhancer equalizer levels.
-5 : Bass - Enhancing the low frequencies, this adjusts the sound
quality for a lower clear sound level.
0 : Normal.
+5 : Treble - Enhancing the high frequencies, this adjusts the sound
quality to a higher sharp level.
-5 : Bass
0 : Normal
+5 : Treble
Duplex
Duplex mode can be turned on or off on the duplex channels.
When turned on, the transmit channel will be as shown in the table on
page18.
Priority Channel Set
A priority channel can be stored in the menu.
The letter “PRI” will appear when the seleced channel is set to Priority.
This channel will then be automatically monitored during the Priority Scan.
Note: You can only store one channel as your priority channel.
Scanning
The UHF305 has two types of scanning: Open scanning (OS) and
Priority scanning (PS).
