Registration
A registration is stored in the device for each communications system on which the handset has
been logged in. A registration entry also includes a system name (e.g. A, B, C,..).
If you have logged into the system with your handset, this name appears on the display.
Subscription
After the handset is subscribed in one or more communications systems you can use the telephone
to make and receive calls. If the
Auto search feature (see page 62) is activated, the handset (in idle
mode) automatically selects the nearest accessible system and logs in there. If you don’t want to use
the
Auto search feature, you can use the stored registration entries to carry out a manual log-in on
any system you want.
