Radio unit monitor
This feature is controlled by a software license
(SFE) and may not be available with your radio.
This software license is only required for the
radio that sends the radio unit monitor request.
The receiving radio does not need the software
license.
This feature is only available for digital channels
operating in conventional mode, and for radios
configured for dispatcher operation.
The radio unit monitor feature can be used when you
are concerned about the safety of a radio user on your
system. When you send a radio-unit monitor request
to a radio, it calls you back without giving any
indication that it is making a call. You can hear any
activity near the radio for up to 20 seconds.
