Talking and listening
It is good radio etiquette to monitor the channel for activity before you transmit, to
ensure that you do not interrupt other users already on the channel.
Press and hold the button to check for channel activity. If you hear static, the
channel is clear for use. Your radio has 40 channels. If you are in a group and you wish
to talk to each other, all radios must be set to the same channel and interference
eliminator code (CTCSS). If you experience interference and need to change channel,
ensure that you change the channel and code of all radios in your group.
1. For maximum clarity, hold radio 5 to 7cm’s from mouth.
2. Press and hold and speak to the microphone. LED indicator light glows
continuously when transmitting.
3. To receive messages, release .
Interference eliminator codes (CTCSS)
The radio has 38 interference eliminator codes (CTCSS) providing you with a choice of
channel/code combinations to listen to transmissions using the same CTCSS code on
the same channel, effectively blocking out unwanted conversations.

one that interests you. More importantly, you can find someone in your group who has
accidentally changed channels and is talking during your scan.
1. To start scanning, briefly press and release the button.
2. If you activate scan while the CTCSS code is set to 0, then the radio will check for
any activity on each channel, regardless of the CTCSS code in use on that channel.
3. If you activate scan while the CTCSS code is set at 1 to 38, then the radio will check
for any activity on each channel, except the CTCSS code 0 in use on that channel.
