6.32 DYNAMIC REGROUPING
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.

6.33 GPS COORDINATES
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:

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]

6.34 V-TAC FUNCTIONS
When a mobile radio detects that it is part of a V-TAC configuration, two additional menu items become
available: “Vmode Menu” and “Vchan Menu.” The “Vchan Menu” is available only when a V-TAC is
operating in the special mode referred to as the Scene-of-Incident mode (SOI).
available: “Vmode Menu” and “Vchan Menu.” The “Vchan Menu” is available only when a V-TAC is

The “Vmode Menu” permits user selection and control of one of four (4) different V-TAC operating
modes:

6.34.1
Extended Coverage Modes (“XCOV” & “XCOV-TG”)
General Information
In addition to all standard mobile radio operating capabilities, Extended Coverage adds the V-TAC’s
bridging (vehicular repeat) functionality for accessing the OpenSky radio network using connected
portable radios. Each portable radio connected to the V-TAC using Extended Coverage is considered a
“client” on the V-TAC. Extended Coverage benefits (permitted) portable radios since it allows them to
get network connectivity using the V-TAC’s higher transmit output power and better antenna system. In
