Expanded System
General Information
DECT (Digital Enhanced Cordless Telephone) technology offers superior perfor-
mance, clarity and security using its completely digital method of transmission.
You can:
- Use (register) up to 4 handsets with the same base unit.
- Use (register) up to 2 base units with the same handset.
- Make internal calls (intercom) and transfer calls between handsets using the same
base unit.
Additional base units and handsets can be purchased from your local retailer.
This model is GAP (Generic Access Profi le) compatible, which means that the
handset and the base unit can both be used with most GAP compatible units
irrespective of manufacturer.
Multiple Base Units
By connecting several base units to the system, the useful range for the handset can
be expanded.. Registering multiple base units with the handset will cause the handset
to automatically connect to another base if and when it loses contact with the current
base unit Another practical application could be to have one base station at home and
one at work. Then the same handset can be used in both places.
The handset remains in contact with its base unit until it goes out of range. When this
happens, the handset will begin to search for another base from its list of registered
base units. It is essential that the range of the base units overlap, in order to achieve
uninterrupted coverage. The transfer from one base unit to another will then be
automatic, however, this will not occur while a call is in progress. If not, there may
be reduced communication in certain areas where the handsets have no signal from
the base units.
More about placement of the base units on the next page.
IMPORTANT!
Automatic switching between base units (handset handover) will not occur while a call is in progress.
