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.
  • Do not use the device in a potentially explosive setting (e.g. Around pumps, on the lower deck of a boat, or around a fuel-storage installation or chemical products) If traveling in a car or by bike, stop before using the device.
  • Switch off the device if on an airplane or in a hospital,
  • Never use the device in close proximity to the radio to avoid interference.

The device is in “Reception” mode when it is turned ON and not transmitting. When a signal is received on the current channel, the LCD will display receiving icon.
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.
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.
2. Don’t try to use two devices that are less than 1.5m (5 feet) apart. Otherwise, you may experience interference.

5. Changing Channels:
Press the MENU button once, the channel number will flash on the display.
Press the up▲ /down▼ button to change the channel. Press the PTT button to confirm and return to standby mode.
If no button is pressed within 15 seconds during the setting, the device will return to standby mode.

Press the PTT button to confirm and return to standby mode. This license-free radio operates on the 476MHZ frequency band; the device has 80 available radio channels. If there are any device users near you, there is a chance that some of the users are operating on the same radio channel. To prevent you from receiving signals from other users, sub-channels have been integrated. When using CTCSS, a low-frequency tone (between 67-250Hz) will be transmitted along with the voice signal. There are 38 available tones to choose from. You are free to choose one of the 38 available sub-channels. Due to filtering, these sub-channels will generally not be audible so they will not disturb the communication.

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.
