User Guide
UHF300 Micro 5watt UHF CB Radio
Downloaded from www.cbradio.nl

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 will 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.

Important information
Please read before installing or operating Your
Oricom Radio
The operation of this 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 and
operation is subject to conditions contained in those licenses.
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
Installation
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.
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.
Screw the mounting bracket and microphone bracket to firm surfaces.
To install the radio:
1. Fix the radio bracket in a suitable location.
2. Then fix the radio in the bracket using the thumb screws.
Fitting the Microphone
The microphone uses RJ type telephone plug and socket:
1. position the microphone plug so the plastic flap faces downwards,
and press the plug into the socket unitl 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.
DC Power connection
The Radio is designed for 13.8 Volt DC, negative earth installations only
(i.e where the negative battery terminal connects to the chassis of the
vehicle). For installion on 24 volt system an inverter (not supplied) will
need to be used.

Installation
Over voltage protection
The Radio ha a high voltage input detection system, to warn you if an
overvoltage situation occurs.
Example: if the power supply voltage exceeds 17 volts DC, the channel
display (LCD backlight) will flash in 7 different colors when the unit
is turned on. In addition, when transmitting, the TX RF power will
automatically select a low power output.
If the overvoltage warning appears, you must switch your radio off and
disconnect it from the power source, before locating the cause of the
trouble. The power source must not exceed 30 volts.
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 batteries 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 +13.8Volts 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 batteries negative terminal.
The radio 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 sensativity.
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.
Optional accessory
If required you may install an external (8 ohm, minimum 5 Watt power)
speaker fitted with a 3.5mm plug (not supplied)
The jack is located on the rear of the radio.
