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 widebnad 40 channel use to narrowband 80 channel use.
During this time wideband channel use will be gradually phased out as users upgrade their existing radios.
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 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 an 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.

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 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.

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 +13.8 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 batteries 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.

channel is located, scanning will pause, this will allow the signal to be
heard. As soon as the channel is clear for 5 seconds, scanning will continue
automatically.
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
