Starting operation of your telephone
Handset Subscription (Checking In)
Your handset can be operated in up to ten different communications systems. To be able to do this, it
must be subscribed to every system, this means: the handset must be checked in.
If you are operating your handset in the Comfort Pro communications system, checking in your hand-
set will be done by your system administrator.
