Technical information
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
one telephone line. Your Quartet 3500
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.
Please note that any additional handsets
and chargers registered to the base
unit, will not add to the REN figure.
