a system PIN known only to yourself. The sys-
tem PIN must be entered when, for example,
registering/de-registering a handset to/
from the base or when restoring the default
settings.
Changing the system PIN
You can change the 4-digit system PIN set on
the base (default setting:
0000
) to a 4-digit
PIN known only by you.
