units
10.1.1 Additional cordless
handsets
Up to 6 cordless handsets can be registered to a
single base unit. Additional cordless handsets,
for example, will allow you to have an intercom
call with another cordless handset while the third
cordless handset is on an outside call. See page
5 for accessory information.
10.1.2 Additional base units
Cordless handsets can be registered to up to 4
base units, allowing you to add additional base
units and extend the area in which your cordless
handset(s) can be used. If a cordless handset
moves out of range of its base unit when "Auto"
is selected on base unit selection (page 78), it
will look for another base unit to make or receive
calls. Each base unit forms 1 radio cell.
Note:
L Calls will be disconnected when the cordless
handset moves from one radio cell to
another.
L Intercom calls and call transfers are only
possible between cordless handsets in the
same radio cell.
