Technical information

How many telephones can I 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
one telephone line. Your BT Cordless Headset H55 has
a REN of 1. A total REN of 4 is allowed. If the total
REN of 4 is exceeded, the telephones may not ring.
With different telephone types there is no guarantee
of ringing, even when the REN is less than 4.
Any additional handsets and chargers that you register
have a REN of 0.
