Dialling and Control Functions
Valid Keys
The key scanning is enabled in off-hook mode with
V
DD
above V
REF
. A valid key is detected from the
keyboard by connecting the appropriate row to the
column (R
ON
< 1 k
). This can be done using an n x
m keyboard matrix with single contacts. Three diodes
and a resistor are used to extend the number of rows
(see Figure 4: Keyboard Layout).
PIN Code
A PIN code is available for protection various user
settings. The default PIN code is set to 1111 and can
be change as follows:
1. Press
[PG]
to enter programme mode
2. Press
[1]
+ (PIN) +
[0]
3. Key in new PIN code (valid digits: 0 - 9, #)
4. Key in new PIN code again
5. Press
[PG]
(= store and exit) or go on-
hook to abort
It is also possible to reset the PIN code through set-
up programming:
1. Press
[PG]
to enter programme mode
2. Press
[0)
+ (Password) +
[#]
+
[0]
3. Press
[1]
to reset
4. Press
[PG]
(= store and exit) or go on-
hook to abort
Call Restriction
A call restriction function is accommodated. This
function can be activated using the PIN code.
Storing digits for call restriction:
1. Press
[PG]
to enter programme mode
2. Press
[1]
+ (PIN) +
[
]
3. Press
[1]
for first call restriction and
[2]
for second call restriction
4. Key in digits for call restriction (2 digits,
[MT] for blank)
5. Press
[PG]
(= store and exit) or go on-
hook to abort.
Key Lock
A key lock function is provided to allow the user to
protect the telephone from any mis-use. When this
function is available through the set-up programming,
it is possible to enable/disable the key lock using the
user PIN code.
Enabling/disabling key lock:
1. Press
[PG]
to enter programme mode
2. Press
[1]
+(PIN) +
[#]
+
[6]
3. Press
[1]
for enable or
[0]
for disable
4. Press
[PG]
(= store and exit) or go on-
hook to abort
Also an easy key lock function is provided. This
function can be activated/disactivated when the key
lock function is available through set-up programming
and the previous mentioned key lock through PIN
code is disabled.
Clear Memory Procedure
It is possible to clear all stored numbers by using the
PIN code as follows:
1. Press
[PG]
to enter programme mode
2. Press
[1)
+ (PIN) +
[#]
+
[7]
3. Press
[1]
for clear
4. Press
[PG]
(= store and exit) or go on-
hook to abort
Reset to Factory Settings
It is possible to reset all settings to the default factory
settings with following procedure:
1. Press
[PG]
to enter programme mode
2. Press
[1]
+ (PIN) +
[#]
+
[8]
3. Press
[1]
for reset
4. Press
[PG]
(= store and exit) or go on-
hook to abort
