Setting up the sub-channel CTCSS/ DCS code
Setting up a sub channel allows you to not be disturbed by other
handheld transceivers transmitting on the same channel or get any
interference from other sources using the same frequency.
Step 1: Press the Menu button 6 twice and the sub channel indication
26 starts flashing.
Step 2: Use the Up button 5 or the Down button 8 to set the desired
sub-channel (1 - 121) or disable this function by selecting "0".
Step 3: Press the PTT button 14 to confirm which channel you prefer.
Disable the CTCSS/ DCS code
To disable the CTCSS or DCS code, select the code "0". "0" will appear
in the menu.
NOTE: Handheld transceivers with a sub channel "0" can receive all
signals on that channel, also when you have set a sub channel on your
handheld transceiver.
Channel monitoring
You can use this function to disable the noise reduction, allowing you to
also listen to weak transmitters on the current channel.
Step 1: Press and hold the Monitor/ Channel Scan button 7 for 3
seconds to disable the noise reduction and to monitor the channel.
Step 2: Release the button 7 to turn the noise reduction on again.
Voice-controlled send function (VOX)
The handheld transceiver will start transmitting as soon as it detects your
voice something like using the hands-free function of your mobile phone.
This allows you to send a message without pressing the PTT button 14 .
Using this function is not recommended when you are located in a noisy
or windy environment.
Step 1: Press the Menu button 6 4 times. The VOX icon 22 will
illuminate in the display and the current VOX setting will flash on the
display 1 .
