Using a PMR device
To communicate between PMR devices they need to be set all on the same channel and CTCSS/
DCS code (see chapter "13.7 CTCSS (Continious Tone Coded Squelch System) / DCS (Digital
Coded Squelch)" and within receiving range (up to max. 10 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
12
.
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
if the Roger Beep is enable (see chapter "13.12 Roger Beep On/Off" ). To reply, just press the
-button
12
and speak into the microphone.
PTT
If 2 or more users press the
will receive only the stongest signal and the other signal(s) will be
supressed. Therefore you should only transmit a signal
12
(press
PTT
- 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 PMR's
may in some extreme cases be restricted to a maximum of a few tens of
meters. You will soon notice that PMR works best when there is a minimum
of obstacles between users.
