10. Call Back
The AVN-TB20AR and AVN-TB20AD maintain a list of the last 18
unanswered intercom calls so that they can be returned if required. The
main display shows the current number of missed calls in the upper le� side
of the screen. With no missed calls, the display shows “CB:00” and the text
is not highlighted. When a call is missed, this indicator is highlighted, the
number is incremented to show the total number of missed calls, and the
call back bu�on starts to flash green.
Call Back List
The call back list is only available when missed calls have been registered.
To access the call back list, press the call back bu�on. The bu�on
illuminates red and the display changes to show the call back list
informa�on – see Fig 10-1.
