Menus and button function will vary depending upon system programming, radio
hardware, and optional configurations.
No V-TAC-related menus are displayed on non-V-TAC radios/control heads.
The “Vchan Menu” is only displayed if the V-TAC is in the SOI mode.
If a V-TAC is in an Extended Coverage mode (XCOV or XCOV-TG), the number of
portable radios (“clients”) connected to the V-TAC is displayed in the bottom line of the
dwell menu.
If a V-TAC is in Extended Coverage for a talk group (XCOV-TG), the selected talk
group and profile in use is displayed.
6.13 DUAL-TONE MULTI-FREQUENCY
Dual-Tone Multi-Frequency (DTMF) is the system used by touch-tone telephones. DTMF assigns a
specific tone frequency to each key so a microprocessor can easily identify its activation. The radio
supports DTMF with a system model control head (Figure 6-1). This allows for specific tasks such as
entering a user ID and password, or selective calling.
When a key on the DTMF keypad is pressed, the DTMF tone is played through the radio’s speaker.
