When in the failsoft mode, operation is in the conventional mode on 

a preprogrammed failsoft channel. If a transmission is attempted before a 
failsoft channel is located, a continuous tone sounds until the PTT switch 
is released. When the radio system returns to normal operation, this 
condition is automatically detected and normal operation resumes. 

Scanning on a SMARTNET/Smartzone channel is similar to the 

standard and radio wide scanning described starting on page 20. Each 
channel can be programmed with a different scan list that includes up to 
16 channels, one of which can be a priority channel. 

Scanning is enabled/disabled by the Scan option switch. In addition, 

channels can be programmed so that scanning automatically starts when-
ever the channel is selected. Scanning is temporarily disabled and “S” 
turns off if a channel is selected that has scanning disabled. Then when a 
channel is selected again that permits scanning, it is automatically 
re-enabled. 

In addition to calls on channels in the scan list, pages, private calls, 

and telephone calls are received while scanning. Messages on the priority 
channel are received while listening to lower priority messages. However, 
private and telephone calls are not interrupted by calls on the priority 
channel. 

The dynamic regrouping feature allows a dispatcher to switch users 

to a dynamically defined channel to receive an important message. 
Dynamic regrouping operates as follows:

1. When this command is received, the alternating dynamic regrouping 

tone sounds, the transceiver automatically changes to the regrouping 
channel, and the display alternately indicates “REGROUP” and the 
alias of the selected channel. All transmitting and receiving then occurs 
on this channel.
