SA545 Datasheet, PDF (10/18 Pages) Sames – PULSE/DTMF SWITCHABLE DIALLERS WITH 10 REPERTORY MEMORIES

SA545
Notes:
i) Only valid keys will be accepted while a store is being programmed (e.g. if
REDIAL is pressed while programming a store, it will be ignored).
ii) Dual mode (i.e. LD and DTMF) numbers should be programmed into the store
using the procedure outlined under 'Dialling Mode Selection'. When redialling
from a repertory store, if an LD/DTMF mode change is encountered, dialling will
halt (and the speech circuit will be reactivated) until told to continue by the user.
It should be noted that if a mode change is entered into a repertory store, it will
require one store location.
iii) Pauses may be stored in repertory stores.
This is achieved by pressing the PAUSE key while programming the store.
When redialling from a repertory store, and a pause is encountered, dialling will
halt (the speech circuit will be reactivated) until told to continue by the user. A
pause will require one store location.
To dial a number from a repertory store: (Whilst off-hook and not already dialling)
1. Press the REDIAL key once
2. Press the number (0-9) of the store to be dialled
Dialling will now start
3. If dialling halts due to an LD to DTMF mode change or a pause instruction, further
dialling will be resumed by pressing the REDIAL key or the PAUSE key.
(Alternatively, pulling C4 low for a minimum of 14ms will have the same effect).
Notes:
i) If an LD/DTMF mode change instruction is encountered while dialling from a
repertory store, dialling will halt. If further dialling from this store is invoked (as
described above) it will be in DTMF mode.
ii) Digits may be dialled manually, or a Last Number Redial carried out before
dialling from a repertory store. In this case, when repertory dialling is invoked.
it will commence in the mode that was current immediately before repertory
dialling was invoked.
iii) Further dialling (either manual or repertory) is allowed after repertory dialling.
Subsequent dialling will commence in the same mode of the last digit dialled
from the repertory store (even if dialling halted at an LD/DTMF switchover).
iv) If an LD/DTMF switchover is stored in the first location of a repertory store, the
following digits will be dialled in DTMF without first halting.
v) All key inputs will be ignored whilst a number is being dialled from a repertory
store. Only when dialling has stopped, will further key inputs be recognised.
