To exit this mode, cycle radio power or press and hold the Emergency switch.
6.9.3 External Emergency Feature
A special man-down switch (currently available only from third-party vendors) is attached
to the accessory connector of the radio. Then 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 switch was
pressed. The emergency can be canceled by a press and release of the Emergency switch.
Note that accessories such as speaker-microphones cannot be used with this feature.
6.10 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” and the alias of the selected channel are alternately 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 talk group). 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.
6.11 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 4.9 and 4.10.
• Scanning is turned on and off by the Scan option switch or menu parameter. Talk
groups (channels) can be programmed so that scanning automatically starts when the
talk group is selected (Autoscan).
• When responding to calls in the scan mode, the programming of the Talkback Scan
parameter determines if a response always occurs on the talk group of the call (Active
Group) or the Selected Group if they are different. Transmissions at other times always
occur on the selected talk group.
• Each talk group can be programmed to select one of the programmed scan lists or “No
List” (scanning is disabled). If scanning is enabled and the selected channel does not
