Locking the telephone
You can protect the telephone against unauthorised use by locking it with a PIN
(Personal Identification Number). You can enter this PIN y ourself and also change it
at any time. Others will then only be able to use your telephone for dialing internal
or emergency numbers and to accept calls, depending on the locking level.
You can choose from 5 different locking levels (not included as standard, if required,
please refer to the TENOVIS Service).
