If you do not press any button within a predefined timeout, the intercom sends a
hang-up signal and hangs up. The timeout is 5 seconds; every character is
followed by 30 seconds for you to think over your setting. The 5-second limit
starts when the intercom has read all that relates to the current user position in
the programming menu. The timeout can be prolonged – see the chart.
Tip
To check programmed values: enter parameter number and , listen
the parameter value and press for return to the main menu.
Deleting All Passwords, All Memories, Complete Initialisation
The following three functions facilitate your programming by clearing all previous
settings:
997 – deletes the entire password list for switch including password 00.
998 – deletes memories of all buttons (01–02) plus Arrival/Departure and Day
/Night passwords.
999 – clears the whole memory and resets the default values (see the chart).
Protection against Unintentional Deletion
The above functions need no special "value" but must be protected against
unintentional initiation. Therefore, enter the service password as the value. Warning:
Full initialisation takes a few seconds, the intercom sends a continuous tone while
memory clearing. Functions 997 and 998 take a little less time and are signalled by a
continuous tone too.
The button memories can be deleted individually too – just enter a "blank" while
programming. For example:
– clears memory 1 of button 01.
