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 both switches including passwords 00
and 11.
 998
deletes memories of all buttons (01 - 54) 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, 2N® Helios 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.
If You Forget the Service Password
If you forget the service password, contact the manufacturer. The manufacturer can
change your service password to 12345 remotely without altering any other
parameter.
