7-14 53SL ES Series Mobile Radio Operating Manual April 2009
Failsoft Operation Section 7 - SMARTNET / SmartZone / P25 Trunked Features
4 All group calls which follow are then emergency calls (private, telephone, and call alert
calls are not allowed). If the channel is changed, the call is made on the emergency
talkgroup programmed for the new channel. If the Surveillance Mode is enabled (see
Section 5.10), all indicators, lights, and tones are disabled. If “No Receive Activity
During Emergency” is programmed, receive audio, the front panel LED, and receive
icons are disabled in the receive mode.
Note
Communications between the radio with the emergency and the dispatcher are closed.
That is, other stations in the talkgroup can see “EMERGENCY” toggle on their displays,
and can listen to talk between the dispatcher and the radio with the emergency, but cannot
talk to that radio.
5 To exit this mode, cycle radio power or press and hold the Emergency switch.
7.10 Failsoft Operation
If a failure occurs in the SMARTNET/SmartZone or P25 Trunked system so that it cannot
be used, the system directs the radio to automatically enter the failsoft mode. When in this
mode, “FAILSOFT” is displayed. A failsoft tone may also be heard, depending on how the
repeater is programmed.
When in the failsoft mode, operation is in the conventional mode on the preprogrammed
failsoft channel (a different failsoft channel can be programmed on each talkgroup). If a
transmission is attempted before a failsoft channel is located, a continuous tones sounds
until the PTT switch is released. When the radio system returns to normal operation, this is
automatically detected and normal operation resumes.
7.10.1 Programmable Failsoft Connect Tone
On a SMARTNET or SmartZone trunking system(s), a different radio failsoft connect tone
can be programmed. This allows the radio to emit a distinct and different tone for failsoft
than tones used during other operating modes.
The failsoft connect tone setting will normally be selected to "Default." This means that
the connect tone used during failsoft will be the connect tone setting the system sends over
the air, or the programmed connect tone if no over the air value is received. If it is known
what the connect tone will be during failsoft operation, this can be programmed using the
PCConfigure application. If a value other than "Default" is programmed, the radio will
always use this connect tone setting during failsoft operation.
