This section describes the parts of your handset and its functions.
For details on the functions see the following pages.
Ringer Equivalence Number (R.E.N.) (UK only)
Your British Telecom line has a maximum R.E.N. capacity of 4. Your Canon unit has a
R.E.N. value of 1 (unless otherwise stated), and this handset also has a R.E.N. value of
1. You can therefore use additional equipment with a total R.E.N. value of up to 2.
If the R.E.N. value exceeds 4, the ringer volume will be reduced and one or more of the
connected equipment may not function.
