Locking Your Telephone Interface by the System
Administrator
The system administrator can lock your telephone interface via a setting for your user
group. All keys of your telephone no longer function aside from a few exceptions (e.g.
the receiver key and the number keys).
• You can still make calls with your telephone but no system functions can be con-
figured.
• The redial function, the communications system telephone books, the Info menu
and the state-dependent menus cannot be activated. (The state-dependent
menus are described in the Telephoning starting on page 63 chapter). The per-
sonal phone book of the mobile unit is, however, available because the lock only
affects communications systems functions.
• If the system administrator has authorised you to do so, you can set the time
group of the communications system (please refer to the chapter entitled System
menu “Central settings” starting on page 128). If your user group authorisation
changes according to the time group, then it is possible that your telephone’s
interface lock will be cancelled due to a change in time group.
Please contact your system administrator if you have questions regarding your
authorisations.
