does not occur. This feature is initiated only on the 
first press of the Emergency switch. Subsequent 
presses do not trigger automatic transmissions. To 
reset this function, the channel must be changed or 
power cycled.

Placing an Emergency Call

1. If required, select a channel of a system on which 

Emergency Calls are enabled and press the Emer-
gency option switch. The Emergency Alarm is then 
sent as described in Section 5.10.2 if applicable.

1. The emergency mode is indicated when “ACK 

RCVD” is briefly displayed and then 
“EMERGNCY” and the emergency talk group are 
alternately displayed. 

2. 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. 

3. All group calls which follow are then emergency 

calls (private, telephone, and call alert calls are not 
allowed). If the channel is changed, the call is made 
on the emergency talk group programmed for the 
new channel. If the Surveillance Mode is enabled 
(see Section 4.9), all indicators, lights, and tones are 
disabled.

4. To exit this mode, cycle radio power, change chan-

nels, or press and hold* the Emergency switch.

If a failure occurs in the SMARTNET/Smart-

Zone 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 preprogrammed 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 contin-
uous tones sounds until the PTT switch is released. 
When the radio system returns to normal operation, 
this is automatically detected and normal operation 
resumes. 

6.12.1  GENERAL

Scanning on a SMARTNET/Smartzone or P25 

Trunked system is called Priority Monitor Scan. The 
following are unique features of this type of scanning. 
For general scanning information applicable to all oper-
ating modes, refer to Sections 4.11 and 4.12

•

Scanning is turned on and off by the SCAN option 
switch. Talk groups (channels) can be programmed 
so that scanning automatically starts whenever the 
talk group is selected (Autoscan). 

•

When responding to calls in the scan mode, the 
programming of the Talkback Scan parameter deter-
mines 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.

•

Up to 256 scan lists or the number that fit in avail-
able memory can be programmed. Each list can 
include up to 256 talk groups from the same system, 
one of which can be a priority group as described in 
the next section. 

•

If the SCN ED option key is programmed, scan lists 
are user programmable (see Section 6.12.3). In addi-
tion, nuisance channels can be temporarily deleted 
as described in Section 4.11.6.

•

Each talk group is 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 permit scanning, it is automatically 
enabled again when a channel is selected that 
permits scanning.

•

The selected scan list can be temporarily changed if 
the Scan (List) Select option switch is programmed. 
The procedure is described in Section 6.12.3.

* This feature requires firmware 1.24.1/2.2.1/3.2.1 or 
later and PCConfigure 1.22.0 or later.
