3.16.3 Mobile-Only Mode (“Mobile”)

The Mobile-Only mode is user-selectable from the “Vmode Menu” or the

radio can be configured to enter this mode automatically. When utilized,

portable radios (clients) cannot connect to the V-TAC. In this mode, the

V-TAC provides two-way communications and it acts like a standard M-803

mobile radio. Refer to the following section for instructions on choosing this

mode.

3.16.4 Changing V-TAC Mode

Use the following procedure to change between the Mobile-Only mode and

one of the three (3) V-TAC-related modes:

1. Press the ▲ or ▼ button until “Vmode Menu” appears in the bottom line

of the display. The current mode appears in the top line (Mobile, XCOV,

XCOV-TG or SOI).

2. Press the ◄ or ► button to select another mode.

3. Press the Select button. A yes/no confirmation prompt appears.

4. To confirm the new selection, press ► to toggle to “Y” (yes).

5. Press the Select button.

6. If the SOI mode was selected, the “Vchan Menu” automatically appears;

choose a radio frequency channel using the ◄ and ► buttons, and

confirm by pressing the Select button. If selecting the SOI mode, observe

the WARNING on page 56.

NOTE

Instead of using the “Vmode Menu,” some radio

installations may be configured to automatically enter a

V-TAC mode when a dash-mounted switch is flipped or

some other action is performed. For example, the V-TAC

can be wired and configured to automatically enter the

XCOV mode when the vehicle’s portable radio is

removed from its vehicular charger. See section 3.16.1.3

on page 55 for additional information.

3.16.5 Displaying V

TAC Information

When using a V-TAC mode, repeated depressions of the Select button causes

the following information to appear in the bottom line of the dwell display:

• XCOV and XCOV-TG modes only: Total number of portable radios

(clients) currently connected to the V-TAC.

• XCOV-TG mode only: Talk group currently used for XCOV-TG

communications.
