Reset to Factory Settings
It is possible to reset all settings to the default factory
settings with following procedure:
1.
Press
[PG]
to enter program mode
2.

Dial Mode Selection
The default signaling mode (LD or MF) is selectable
through following procedure:
1.
Press
[PG]
to enter program mode
2.
Press
[3]
to enter dial select mode
3.
Press
[0]
for LD and
[1]
for MF
4.
Press
[PG]
(= store and exit) or go on-hook to
abort
When default LD mode is selected, a temporary change to
MF can be invoked by pressing the
[
]
key. Temporary MF
select with tone on first key pressure can be selected as
option (see also Table 3: Parameter settings). The circuit
will revert to LD by pressing the
[FL]
key or by next on-
hook.
Re-Dialing (Last Number Redial)
Re-dialing is a facility that allows re-signaling of the last
dialed number without keying in all the digits again.
Numbers dialed out from any memory will also be stored in
the LNR memory. The re-dialing works in following manner:
-
Any digit (including Flash, Pause, and MF select) being
dialed is storable in the LNR memory up to a total of 31
digits.
-
If more than 31 digits are entered, re-dialing will be
inhibited.
-
Pressing the
[R/P]
key as first entry after off-hook
(LNR cursor at first digit) will invoke dialing the content
of the LNR memory.
-
If the
[R/P]
key is pressed after entering one or more
digits, the key will function as a pause key and each
pressure will insert a pause.
Pauses can also be inserted by pressing the
[R/P]
key in
program mode.
Flash Function
A flash,
[FL]
key, activation will invoke a timed loop break.
The flash duration can be programmed through set-up (see
Figure 2: Keys for HEX-code entry and Table 4: Timing
selection by HEX code):

Flash Duration
Flash 1
Flash 2
One of two pre-programmed can be selected as follows:
1.
Press
[PG]
to enter program mode
2.
Press
[2]
to enter flash select mode
3.
Press
[0]
for duration 1 and
[1]
for duration 2
4.
Press
[PG]
(= store and exit) or go on-hook to
abort
A flash entered will be stored in the LNR memory together
with entered digits. After a recall a 270 ms pause will
automatically be executed.
Pauses
Pauses can be inserted if the
[R/P]
key is pressed after
entering one or more digits. Also during programming,
pauses can be inserted by pressing the
[R/P]
key. Default
pause duration is 1 second (P1) and an alternative pause
of 3 second (P2) can be selected. These pauses can be
changed through the set-up programming (see Table 3:
Parameter settings)
Memory Keys
The keys
[M1]
to
[M8]
are direct memory access keys,
[SH]
key is used to access second level of direct
memories, and the
[MR]
key is used for key-code dialing.
Up to 26 numbers can be stored in the on-chip RAM. Each
number can contain up to 21 digits (including pauses).
During programming multiple pauses can be inserted by
pressing the
[RD]
key.
Example (45678P123 is stored in M1, where P is a pause
and 123 the extension number):
1.
Off-hook, wait for dial tone
2.
Press
[M1]
-
45678 is dialed out
-
Dialing halts (pauses)
-
Dialing is resumed, 123 is dialed out.
Memory dialing is cascadable up to a the maximum of 31
digits/data.
