19 Trunked Radio Features Operation
The "failsoft" feature ensures that you will continue to have radio
communications capability in the event of trunked system failure. During trunked
operation, the radio will automatically go into failsoft operation if the central
trunking controller fails for any reason. While in failsoft, your radio will transmit
and receive on a predetermined frequency in a conventional, as opposed to
trunked, mode. When the trunked system returns to normal operation, the radio
will automatically leave failsoft operation and return to trunked operation.
When the radio is in failsoft operation, you will hear a faint "beeping" sound
every ten seconds, and the radio will become unsquelched.
The trunked telephone feature allows you to receive calls similar to a standard
telephone.
