Tyco Electronics P5200, P7200 8.29 DYNAMIC REGROUPING , 8.30 GPS COORDINATES , 8.31 V-TAC FUNCTIONS

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

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.
