repeated with the acknowledgement "bleeps" again. If the call
is not acknowledged at the end of the fifth play of the message
the unit abandons that call and attempts the next telephone
number. This procedure is repeated three times in sequence for
all three telephone numbers. If no acknowledgement has been
received then the speech dialler shuts down.
Acknowledgement
Options
- The TSD402 may be programmed to stop dialling after the first
call has been acknowledged or when two, or three have been
acknowledged. The acknowledgement may also be disabled
altogether, when the speech dialler is used in this mode it dials
the first telephone number and providing the call is answered it
plays the message and shuts down. If the call is not answered it
dials the next telephone number etc.
Aborting a Call - If the system is accidentally triggered the speech dialler is
automatically shut down when a valid user passcode is entered.
Tone Dialling simulators (Tone Pads)
For the acknowledgement procedure to work successfully the TSD402 "looks" for a 1 second
of tone between 600Hz and 1400Hz. This is supplied most reliably by the [8] button used
for MF dialling although other buttons may work if pressed accidentally.
If the recipients telephone cannot produce a suitable tone then a "Tone Dialling Simulator"
(Tone Pad) may be required. These are available from many high street electrical stores
and also from specialist suppliers such as RS Components (stock code 252-841) and
Maplin Electronics (stock code CK25C).
