User Manual
The use of the citizen band radio service is licensed in Australia by ACMA Radio Communications (Citizen Band Radio Stations) Class License and in New Zealand by MED General User Radio License for Citizens Band Radio. Operation is subject to conditions contained in those licenses.
This lightweight hand-held transceiver is suitable for all manner of recreational and professional activities such as building sites, IT cablers, electricians, inter-car road trip communication, or keeping in touch with the kids while they play. Open field transmission range is up to 6km, with typical city range up to 1km. It runs off 3 x AAA batteries and has features you usually only find in more expensive models, including VOX hands-free, monitor, call tones, roger beep, backlit display, headset connection, and CTCSS sub-channels. There is also an LED torch built into the top in case you’re stuck in the dark. Thanks to the auto-battery saving feature, the batteries won’t go flat in case you forget to turn it off.
Specific Recommendations:
- To avoid the risk of burns, do not use the device if the aerial is damaged in any way.

When you press the PTT (push to talk) button, the device switches to “Transmission” mode.
Hold the device in a vertical position with the Mic (microphone) 3-5cm away from your mouth. While holding the PTT button, speak into the microphone in a normal tone of voice. Release the PTT button when you have finished transmitting. For others to receive your transmission, they must be on the same channel as you.
Note:
1. The maximum talking range is up to 6Km, this will depend on your surroundings and environment. It can be affected by obstructions such as hills or buildings.

UHF CB radio – What you need to know
A few things to note about channel allocation. Channels 5 & 35 are reserved for emergency only, and misuse of these channels carries hefty fines or jail time. Besides these, the truckies use channel 40, 18 is the caravan and campers channel. Channels 1-8 and 31-38 are for repeater use, the latest standard states that 41 – 48 and 71 -78 may also become available for repeater operation to supplement the other repeater channels. Presently speech telephony is inhibited on channels 22 and 23 (i.e. data only). Channels 61, 62, and 63 are currently not activated on all UHF units until approved by the ACMA at some time in the future.
