User Guide
For UHF400R 80 Channel UHF 2-WAY Citizen Band Radio

This unit complies with all relevant Australian
and New Zealand approval requirements
AS/NZS 4365:2011
Why has the ACMA increased the number of available UHF CB channels?
To provide additional channel capacity within the UHF CB Band the ACMA will over the next 5 years change the
majority of the current wideband 40 channel use to narrowband 80 channel use.
During this time wideband channel use will be gradually phased out as users upgrade their existing radio’s.
This means that the new Oricom narrowband radio you have purchased will have more channels than older wideband
radios. Some of these channels are locked and cannot be used, (see the attached channel chart for more information).
When did this take place?
Early in 2011 new AS/NZS Standards came into effect allowing operators to use additional narrowband channels and
also use narrowband transmissions on some current wideband channels. This increased the number of channels up
to 80, 75 of which are useable voice channels.
What issues may users experience during the transition phase?
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.
It is expected that as older wideband radios are removed from service that this issue will be resolved. Most radios in
use will be narrowband eliminating this issue.

Safety Information and Warnings
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 Radio communications (Citizen Band Radio Stations)
and in New Zealand by MED the General User Radio License for Citizen Band
Radio.
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 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
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.
For optimum performance your radio needs to be installed correctly. If
you are unsure about how to install your radio, we suggest for optimum
performance 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 radio.
Using the DIN Kit
The UHF400R comes complete with a DIN kit for mounting in a vehicle dash
board

Installation
Automatic indicator of High Voltage support
The radio has a high voltage input detection system, to inform you of high voltage use.
Eg. : If the power supply voltage exceeeds 18volts DC, The 24v icon display will
appear on the LCD when the unit is turned on.
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 2 Amp fuse to the battery's
positive terminal. Alternatively, the positive lead could be connected at the fuse
box at a point that has 12 or 24 Volts continuously available (preferably the
battery side of the ignition switch) via the 2 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 2 Amp fuse.
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 477MHz
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.
Optional accessories
If required you may install an external (8 ohm, minimum 5w power) speaker
tted with a 3.5mm plug (not supplied).

Operations
Scanning
The radio SCAN function has the ability to allow programmable channels to be
scanned for groups of users.
Channels can be scanned (40 channels per 5 seconds). When a signal is found,
scanning will stop at that channel to allow the signal to be heard, then resume
scanning when the channel is clear again.
Scan Modes
The Radio features three scan modes - Open Scan, Priority Scan and Memory
Scan.
Open Scan
The Open Scan feature scans for activity on all CB channels. Once a channel
is located, scanning will pause to allow the signal to be heard. As soon as the
channel is clear for 5 seconds, scanning will continue automatically.
Open Scan
Priority Scan
With Priority Scan the Radio scans for activity, but in addition, it also inserts your
Priority Channel into the scan sequence.
This means that your Priority Channel will be monitored regularly while scanning
to ensure that no calls are missed. Any signals received on your Priority Channel
will take precedence over any signals received on the other channels.
Instant Scan
During Open Scan press and hold SC/MEM button to start Instant Scan, only
the channels programmed in the instant channel buttons with 'M' set will be
scanned. To stop scan press the SC/MEM button or Push PTT.

Selcall
Selcall or Selective Calling is a function that allows you to selectively call another
radio, using a unique ID number. Your radio has 10 programmable Selcall ID
memories. The ID memories are displayed as "C0 to C9". Here you will program
Selcall ID numbers of other radios.
Your Radio’s Selcall Identication number is preset "12345". You must change
this number to your own unique ve digit Selcall ID number.

16
Operations
Selcall Identication Name
In addition to the Selcall ID number, each Selcall ID can be named using a 5
character ALPHA name. The ALPHA name is stored in memory along with the
ID code. When an incoming Selcall is received and the Selcall matches one of
those in your radio's memory, the name can be displayed instead of the Selcall
ID number.
Recalling Selcall Idents from Memory
1. Press the ID/CAL button to select the CALL TO mode.
2. To select the required Identity in memory locations 'C0' to 'C9', rotate the
channel knob on the front display.
