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.
