Automatic Repeated Multiple Numbers Dialing with
Confirmation
Caution
 This a default ST mode set by the manufacturer, which provides the
highest possible connection reliability. Automatic dialling can disabled or
switched into the ‘no-confirmation‘ mode but, in that case, the
manufacturer assumes no liability for subsequent damage if any.
Up to 6 telephone numbers and the count of dialing repetitions can be stored in the ST
memory for the ALARM button (or 2 numbers where no voice recording module is
available). The ST thus tries to get through to all numbers stored. Tone dialing (DTMF)
is used as the most reliable connection-confirming criterion. The dispatcher must press
button
on its telephone (in the DTMF mode). If the called number is busy or
nobody answers the phone within a defined timeout, or in other cases (as defined in
the table), the ST tries to call the following number from the list until it completes the
pre-defined number of cycles. If the number of cycles is 0, automatic dialing is turned
off and the ST calls to one number only.
In this mode, the ST repeats the “Wait please…“ message (or any relevant user-
recorded message) so many times as preset. The message can be muted by pressing
button , or confirming connection with button .
The ST default mode is “Speakerphone automatic dialing with confirmation“. There are
some other modes designed for specific applications, one of them being
“Speakerphone automatic dialing without confirmation“; see later.
