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. 9 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
-button.
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
-button and speak into the microphone.

If 2 or more users press the
- button at the same time the
receiver will receive only the stongest signal and the other signal
(s) will be supressed. Therefore you should only transmit a
signal (press
- button) when the channel is free.

The range of radio waves is strongly affected by obstacles such
as buildings, concrete/metal structures, the unevenness of the
landscape, woodland, plants, …
This implies that the range between two or more PMRs may in
some extreme cases be restricted to a maximum of a few tens of
metres. You will soon notice that PMR works best when there is
a minimum of obstacles between users.
