Using the PMR
About
channels and
codes PMR has eight channels , numbered 1 to 8 . When you
select a channel, you can communicate on that channel
with other PMR users within range (see page 5).
Each channel also has 38 CTCSS* codes , letting you set
up groups of users within the same channel, for more
private communication. If you have set a code, you can
communicate only with other users tuned to the same
channel and the same code.
You can turn the CTCSS function off, by setting ‘no
code’. This lets you communicate with any PMR user on
the same channel who has also turned off CTCSS (or
whose PMR handset does not have this feature).
!
PMR446 is an open-licence band — always identify
yourself when transmitting, as other people may be
communicating on the same channel.
* CTCSS stands for Continuous Tone-Coded Squelch System.
