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 Oricon 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
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 fire 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 conflicts, turn off your radio in any location where posted notices instruct you to do so such as health care facilities.
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 fitted 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  pecialist 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 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 DC Power 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.
Antenna information
The antenna (not supplied) is of critical importance, to maximize your output power and receiver senstivity.
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 accessories
   If required you may install an external (8 ohm, max 5w power) speaker fitted 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.

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

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 specific channel (all repeater output 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 down converts your signal and retransmits on CH01.
Your transceiver allows you to pre-select Duplex operation individually on each channel.
