How many telephones can you have?
All items of telephone equipment have a Ringer
Equivalence Number (REN), which is used to calculate the
number of items which may be connected to any other
telephone line. Your BT Calypso 1100 has a REN of 1.
A total REN of 4 is allowed. If the total REN of 4 is
exceeded, the telephone may not ring.
With different telephone types there is not guarantee of
ringing, even when the REN is less than 4.
Only use the approved power adaptor and charger.
Only use approved AAA NiMH rechargeable batteries.
Connecting to a switchboard
This product is intended for use within the UK for
connection to public telephone network and compatible
switchboards, which support tone dialling and Timed Break
Recall. If in doubt please consult your service provider.
Access code and entering a pause
If you are connecting your BT Calypso 1100 to a
switchboard/PBX you may need to enter an access code
(e.g. 9) to get an outside line.
