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.
