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 BT6500 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.
