Operating the Walkie−Talkies
An exception here is CTCSS code 0 (zero). When this
setting is set, all calls made on the channel set can be
heard. In order to participate in the radio communication,
you must set the corresponding CTCSS code.
Monitor
The Monitor function enables the search for weak signals on the
channel currently set. If you receive an external signal, switch to a
free channel. Always communicate with other subscribers on a free
channel to prevent interference.

VOX / iVOX
When this function is active, the walkie−talkie automatically starts to
transmit when the unit detects your voice or a sound.
When you start to speak, there is a slight delay before the
walkie−talkie starts to transmit.
Activating VOX mode
When using VOX mode, conversation is carried out via a headset.
Use a commercially available headset
without a PTT button but equipped with
a 3−pin, 2.5 mm stereo jack plug.
Pin assignment:
1 = Loudspeaker
2 = Microphone
3 = Earth
Switch the walkie−talkie off before connecting a headset.
