4.2 DISPLAY OVERVIEW
The display shows the radio status (Table 4-2). Network connectivity (OTP Mode only) and volume icons
appear on the right. The volume level is also represented numerically within the display with zero (0 or
muted) being the lowest volume level and forty (40) being the highest/loudest level. “Mute” displays
when the speaker is muted. The rest of the display consists of two text lines that change in response to
user interaction with the menu buttons. A sample display is shown in Figure 4-2.

detail. At power-up to V-TAC mode (e.g., portable radio not in vehicular charger at V-TAC turn on), the V-TAC will sound
four tones (high-medium-high-medium) as it initiates the default Extended Coverage mode.
4 The length of time necessary to hold the Power Button is configurable. The default time length is one-half of a second.
