USING A PMR DEVICE
To communicate between PMR devices they need to be set all on the same channel and within receiving range
(up to max. 3 km in open field). Since these devices use free frequency bands (channels), all devices in
operation share these channels (total 8 channels). Therefore, privacy is not garanteed. Anybody with a PMR
set to your channel can overhear the conversation.
If you want to communicate (transmitting a voice signal) you need to press the PTT − button (Push to talk).
Once this button pressed, the device will go into transmit mode and you can speak into the microphone. All
other PMR devices in range , on the same channel and in standby mode (not transmitting) will hear your
message. You need to wait until the other party stops transmitting before you can reply to the message. At the
end of each transmission the unit will send a beep. To reply, just press the PTT − button and speak into the
microphone.
