Programming Procedures
Procedure Principles
The procedures for utilizing the features of the AS253x are
optimized out of consideration for the human factor in
order to:
-
-
-
-
-
The following chapters describe the operating procedures
for the provided features. Pressing an invalid key or key
combination during programming will cause the device to
abort the program state. Pressing any key combination or
sequence which is not described or defined may cause the
device to enter a state or mode that does not comply with
the expectation of the user. In such cases, any undesired
state can be terminated at any time by going on-hook / off-
hook which will generate a functional reset.
Storing Numbers (not AS2534)
Up to 14 numbers, each with maximum 21 digits, can be
stored into the internal RAM.
Programming Tone Ringer
Three different ringer melodies with three levels each can
be programmed. AS2534R cannot be programmed.

dialing wrong numbers, deleting stored numbers, etc.
be consistent, simple and usable.
Press [P/M] to enter program mode
Enter location (MR + digit
Enter number - entries (0-9, *, #, PS or LNR, R1, R2,
R3) will b written directly into the selected memory
location)
Press [P/M] to store and exit or go on-hook to abort
Go to 1 for storing further numbers
Press [P/M] to enter program mode
Press [#] for ringer programming mode
Enter Code to select ringer melody and volume(see
code table in section Tone Ringer (Melody/Volume)
Press [P/M] to store and exit or go on-hook to abort

; or M1 to M12)
When Code 0 (tone ringer off) has been programmed, the
device will automatically return to previous setting
(different from 0) by next off-hook.
Temporary MF
The procedure below assumes that the device is operated
in puls mode.
Mode pin is connected to row 1, 2, 3, 4, or 5. When mode
pin = row 5, pressing the [*] key also transmits the tone by
MF selected. The [T/P] key (not AS2535) can be used
alternatively to the [*] key.
Automatic Dialing
The following procedure describes the dialing procedure
and the internal sequences:

Go off-hook
Enter the number by pressing digit, [M1]-[M12], [LNR]
or [MR] + digit
The number is internally buffed in the FIFO
Tone- or Puls-Dialing starts
Wait for connection
Got to 2 for entering postdialed digits
Go off-hook
Press [*] or [T/P] to switch to DTMF mode
Press [R] or [T/P] to switch back to PULS mode
Got to 2. to switch again to DTMF mode
