Viking™ VP600 Portable Radio Operating Manual 6-13
SmartNet / SmartZone / P25 Trunked Features
3 If the preceding Emergency Hot Mic feature is enabled, the call is automatically
transmitted without pressing the PTT switch. If it is disabled, press the PTT switch and
begin speaking as with a standard call.
4 All group calls which follow are then emergency calls (unit, 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 4.10, Surveillance Mode), the radio will behave in accordance to the individual
surveillance mode options. If “No Rx Activity During Emergency” is programmed,
receive audio and the front panel LED are disabled in the receive mode.
5 To exit this mode, cycle radio power or press and hold the Emergency button.
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 to 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.
6.9 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.
When in the failsoft mode, operation is in the conventional mode on the pre-programmed
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.
