Trunking Operation
Failsoft
If the trunked system’s central controller fails for any reason, the radio
indicates failsoft. In this condition, the radio transmits and receives on
a pre-determined frequency in a conventional mode.
Failsoft ensures that you will have communications capability at all
times. Radios can be programmed by a qualified radio technician so
that units that normally communicate on the same trunked mode will
be assigned to the same failsoft repeater frequency.
Since the normal trunking features do not operate during failsoft,
much of the privacy of trunked systems is lost. You must share the
channel with other users until the failure is corrected.
To continue, in failsoft, to communicate with other talkgroups:
If a system that is in failsoft is accessed while in scan, the radio
freezes scan and remains on the failsoft frequency for a period of six
seconds. This time period can be changed by a qualified radio
technician. This time allows the operator to monitor the failsoft
frequency for activity before resuming scanning.
On W7 and W9 Control Heads, the nuisance-delete feature can be
used to temporarily delete the system in failsoft from the scan list, if
desired.
1 Rotate the Mode knob (W4) or press the Mode (W5, W7, W9)
rocker button to change to a different repeater frequency.
The failsoft condition is indicated by a faint beeping tone every
ten seconds (radio unsquelched).
When the trunking system returns to normal operation, the
beeping tone stops.
2 Press the PTT button to talk, and release the button to listen.
