cation code (AC) for this procedure. The IPEI can be read out from the handset's
"System" menu (see page 77); the AC can be obtained from your system adminis-
trator or read out from the Telephony: Devices: DECT Phones menu in the Con-
figurator of the OpenCom 100 / Aastra 800 (Web console).
Subscription
The handset will store a subscription record for each communications system it has
been checked into. Each subscription record includes a name; whenever the handset
enters the range of a base station, this name will be appear in the handset's display.
Registration
Once the handset has been subscribed to (checked into) one or more communica-
tions systems you can make and receive calls. If you have activated the Auto Search
feature (see page 77), the handset will automatically register with the nearest base
station in its range (provided the handset is in the idle state). If you do not want to use
the auto search feature, you can register the handset with a base station using the
subscription record stored in the handset.
