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 S12 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.
