options. If “No Receive Activity During Emergency” is programmed, receive audio and
the front panel LED 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.
6.9.4 External Emergency Feature
A special man-down switch (currently available only from third-party vendors) is attached
to the accessory connector of the radio. 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.

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
