Scanning Mode selections survive power down. At startup, the radio defaults to the scanning mode of set 
during last use. The last selection made remains in effect until a new selection is made from the Scan 
Mode menu. 

The following lists the scanning priority order (from highest to lowest): 

•  Selected talk group in emergency state. 
•  Default emergency group in emergency state. 
•  Selected talk group. 
•  Emergency capable group in emergency state 
•  Priority 1 talk group. 
•  Priority 2 talk group. 
•  Other (non-priority). 

1.  Press the 

 or

 

keys until “Priority1” or “Priority2” appears in the display (Priority1 group has 

higher priority than the Priorty2 group). 

2.  Press the   or   button until the desired talk group is displayed. 

3.  Press the 

 key to select and activate the selection. The radio automatically returns to the Dwell 

Display. 

 

•  Changing the priority of a listen group does not change your talk group. 
•  You set priority for two talk groups, but only in the selected profile. 
•  The scanning priority settings are reset to the default values when the radio is turned 

off.

 

Selective calling is the capability for two voice radio units to obtain and use an independent talk path for a 
unit-to-unit call. A properly equipped radio can initiate a selective call to any radio in the system that is 
also programmed for selective calls. 

In the OpenSky system, a radio can be configured to initiate selective calls through a pre-programmed list 
in memory called a speed dial list. Alternatively, a properly equipped radio can initiate a selective call to 
any radio in the system by entering the ten-digit User ID (similar to a telephone number) of the target 
radio. Some radios are configured to only receive (not initiate) selective calls. 

 

Selective calls are terminated if an emergency is declared. The network limits selective 
calls to ten (10) minutes maximum.
