To register handsets from other manufacturers, please refer to the operating
manual supplied with them.
Deregistering handsets
Each handset can deregister itself and other handsets registered on the base
station. Following deregistration, UNREGISTERED appears in the display of the
unregistered handset.
Handsets are deregistered via the menu. Refer to Page 15 for the sequence of menu option
selections.
Multiple base stations
You can increase the range of your handset by registering it on several base stations. The
handset can be registered on up to 4 different base stations simultaneously. Each base sta-
tion requires its own telephone line socket. Connections can be used with the same call
number or with different ones.
Calls in progress cannot be transferred from one base station to another.
