Checking that a channel is clear
Your radio is capable of segregating individuals or groups of
users by means of audible or subaudible tones (known as
signalling). This means that in normal operation you may not
be able to hear all calls being transmitted on a channel.
However, your radio may be programmed with the monitor
function which, when activated, allows you to hear all
activity on a channel. This is useful if you want to check
whether a channel is clear before making a call.
Note: The monitor function may not have been programmed
to override all signalling.

1 Long press the menu key
