Viking Portable 600 Radio Operating Manual
SmartNet / SmartZone / P25 Trunked Features
6.8.4 External Emergency Feature
A special man-down switch (currently available only from third-party vendors) is attached
to the accessory connector of the radio. If this feature is enabled by programming and the
radio is in a horizontal position for longer than the programmed time (0-63 seconds), an
emergency condition is triggered the same as if the Emergency button was pressed. The
emergency can be canceled by pressing and holding the Emergency button. Note that
accessories such as speaker-microphones cannot be used with this feature.

Failsoft Operation
If a failure occurs in the SmartNet/SmartZone or P25 Trunked 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.

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 preprogramming
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.

6.9.1 Failsoft Connect Tone
When using this radio with SmartNet or SmartZone trunking system(s), a different connect
tone during failsoft operation can be programmed. 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, the connect tone during failsoft
operation can be programmed. If a value other than “Default” is programmed, the radio
will always use this connect tone setting during failsoft operation.

6.10 SmartNet / SmartZone / P25 Trunked Scanning Features
Scanning on a SmartNet/SmartZone and P25 Trunked systems 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 4.11 and 4.11.5.
