Viking Mobile Radio Operating Manual 6-17
SMARTNET / SmartZone / P25 Trunked Features
With the emergency press and hold feature enabled, the emergency button must be pressed
and held for the duration of the press and hold timer for emergency mode to be activated.
If the button is released before the timer has expired a bad beep tone sounds and
emergency mode fails to activate. To cancel emergency mode, the emergency button must
be pressed and held for the duration of the press and hold timer again.
6.10 Failsoft Operation
If a failure occurs in the SMARTNET/SmartZone or P25 Trunking system so that system
traffic cannot be centrally managed, 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.
6.10.1 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. If a value
other than “Default” is programmed, the radio will always use this connect tone setting
during failsoft operation.
6.11 SMARTNET / SmartZone / P25 Trunking Scanning Features
Scanning on a SMARTNET/Smartzone or P25 Trunked system is called Priority Monitor
Scan. The following are unique features of this type of scanning. For general scanning
information applicable to all operating modes, refer to Sections 4.12 and 4.13.
