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 Freestyle 4500 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 no guarantee of ringing, even when the REN is
less than 4.
Only use the supplied mains power adaptors, item code 010091 for the base station and
010093 for the charger.
Only use approved AAA NiMH rechargeable batteries.
