1.  Press to declare an emergency.  To clear an emergency, press and hold Option 2 button  .  While 

holding 

, press the emergency button.  Release both buttons when the “emergency cleared” tone 

sounds. 

2.  The radio returns to your default selected talk group. The “EMERGENCY” display is removed from 

the main screen. 

 

 

If the radio is in stealth mode, clearing the emergency will cause the radio to exit stealth 
mode. 

Dynamic regrouping requires that the network administrator determine which radio users should be 
formed into an impromptu talk group to respond to particular emergency conditions. 

The administrator will edit the personalities of the affected radios to include an emergency profile and 
then page the affected radios to re-register with the network to receive their edited personalities. 

In response, affected radios automatically re-register to receive their edited personalities. During re-
registration, subscriber equipment will default to the emergency profile selected by the administrator. 

The radio’s current latitude and longitude coordinates may be displayed using the “GPS” menu. The 
following procedure assumes a GPS antenna is connected to the radio and it is receiving adequate signals 
from GPS satellites. 

1.  Press 

 or

 

until the “GPS” menu appears in the display. Current GPS coordinate latitude and 

longitude data continuously scrolls in the top line of the display in a degrees:minutes:seconds format. 

2.  Press 

 or

 

to change to another menu. 

 

If the internal GPS receiver’s data is expired (30 minutes or more) or unavailable, the 
radio uses the serving base station’s coordinates [GPS (Site) is displayed]. The GPS Menu 
will also indicate if the data is aged (2 minutes or more) [GPS (Aged) is displayed]. 

In addition to all standard portable radio operating capabilities, Extended Coverage adds the V-TAC’s 
bridging (vehicular repeat) functionality for accessing the OpenSky radio network.  Each portable radio 
connected to the V-TAC using Extended Coverage is considered a “client” on the V-TAC.  Extended 
Coverage benefits portable radio users since it allows them to get network connectivity using the 
V-TAC’s higher transmit output power and better antenna system.  

The V-TAC supports two Extended Coverage modes: Extended Coverage for individual users (display 
reads “XCOV”) and Extended Coverage for a talk group (display reads “XCOV-TG”).  Typically, 
Extended Coverage is used after the vehicle’s operator has exited the vehicle with a portable radio unit 
and the portable unit requires this bridging functionality to access the OpenSky radio network.
