USING A PMR DEVICE
To communicate between PMR devices they need to be set all on the same channel/CTCSS code 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 h − 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 h − button and speak into the microphone.
CTCSS (CONTINUOUS TONE CODED SQUELCH SYSTEM)
The 2 digit CTCSS code corresponds to a specific tone frequency the radio emits. Two users, with the
same channel and CTCSS set can hear one another. They will not be able to hear anyone else on the
channel unless the other radios have the same exact CTCSS code enabled.
The exception here is use of the CTCSS code 0". If this code is selected, all conversations on the
channel set can be overheard.
