MM102014V1, Rev. G
5.23.4 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.
5.23.5 Manually Changing V-TAC Mode
CAUTION
When using either Extended Coverage mode (XCOV or XCOV-TG) or the Scene-of-
Incident (SOI) mode, always observe and follow any placarded/posted information
pertaining to minimum required radio antenna-to-antenna distance separations.
Use the following procedure to manually 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. Press the Select button.
5. 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 in Section 5.23.3.
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 the section Changing Between Extended Coverage Modes on
page 50 for additional information.
5.23.6 Displaying V-TAC Information
When using a V-TAC mode, repeated pressions 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.
• XCOV-TG mode only: Profile currently used for XCOV-TG communications.
• All V-TAC modes: Current V-TAC channel. (Does not apply to the Mobile-Only mode.)
• All V-TAC modes: Currently utilized V-TAC mode (XCOV, XCOV-TG, SOI, or Mobile-Only
mode).
