8.28.2.1 Using Manual Encryption
1. Press *32 on the keypad.
2. Enter the key (1 – 16 digits for 128 bit encryption; 17 – 32 digits for 256 bit encryption).
3. Press #.
4. To end manual encryption, press *33.
If a user is engaged in a call on a talk group that has been manually encrypted at the radio level, the user
will see “Secure Call” on the bottom of the dwell display.
If a secure (encrypted) call is in progress, and the user has not entered the key, the bottom of the dwell
display will alternate between “No Access” and the alias of the radio that is currently engaged in the
secure call.
Once the user has terminated manual encryption, “UnSecure” appears temporarily in the bottom line of
the dwell display.
8.29 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.
8.30 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:
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].
8.31 V-TAC FUNCTIONS
8.31.1 Extended Coverage Modes (“XCOV” and “XCOV-TG”)
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.
