General information
DECT (Digital Enhanced Cordless Telephone) is a digital method of
transmission for cordless telephones. You can:
- Use up to 5 handsets with the same base unit.
- Make internal calls (intercom) and transfer calls between handsets using the
same base unit.
- Use (register) up to 4 base units with the same handset.
Additional 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 other GAP-compatible
units irrespective of manufacturer. However, the GAP protocol does not
guarantee all functions will work.
Multiple handsets
The multiple handset function has numerous practical applications, e.g.
employees in an offi ce can have several handsets linked to the same base unit.
They could all answer an incoming call, make outgoing calls, use the handsets
internally as an intercom system, and also transfer external calls between the
handsets. One external call and two internal calls can be active simultaneously.
To be able to use extra handsets with a base unit, you must register the handset.
Registration means that you inform the handset of which base unit it is
connected to.
Registration involves assigning each handset a specifi c handset number, e.g.
“2”. This number is also used for internal calls between handsets. When you
purchased the telephone, the handset was pre-registered with the accompanying
base unit. The handset has the handset number 1, which is shown in the display
in standby mode. Refer to the Registration chapter for more information.
If you wish to use several handsets with one base unit, you should ensure that
the base unit is positioned “in the middle”, to evenly divide the base unit range
among the handsets.
