Emergency alarms and emergency calls are separate functions that 

can be individually programmed on SMARTNET/SmartZone channels. 
The Emergency option switch is required to initiate these features. An 
emergency alarm is a special data transmission to alert your dispatcher of 
an emergency situation, and an emergency call is an urgent request for 
access to a voice channel. The emergency alarm and call are transmitted 
on the emergency talk group or announcement group that has been 
preprogrammed by your system operator on the currently selected 
channel. Proceed as follows to initiate an emergency alarm or call:

1. To transmit an emergency alarm, select a SMARTNET/SmartZone 

channel that has that feature enabled and then press the Emergency 
option switch.

2. The emergency alarm is then transmitted and “EMERGNCY” is 

indicated in the display for a short time. Transmitting continues until an 
acknowledgment is received (indicated by two beeps) or the 
programmed number of attempts have occurred. Silent operation may 
also be programmed in which case no audio or visual indication of the 
alarm condition occurs.

3. To transmit an emergency call, press the Emergency option switch with 

a SMARTNET/SmartZone channel selected that has that feature 
enabled. Then manually press the PTT switch and begin speaking as 
with a standard call. All calls that follow are then emergency calls and 
they occur on the emergency talk group. 

4. To exit the emergency mode, power must be turned off and then on 

again. 

If a failure occurs in the SMARTNET/SmartZone system so that it 

cannot be used, the transceiver automatically enters the failsoft mode. 
When this mode is selected, the display alternately indicates “FAIL-
SOFT” and the alias of the selected channel.
