Connecting External Device

If the connectors of the external devices cannot be connected to the jacks on the FAX,
you will need to purchase one or more B.T. adaptors to connect them as follows:

Ringer Equivalence Number (R.E.N.)

Your British Telecom line has a maximum R.E.N. capacity of 4. Your FAX has an R.E.N.
value of 1 (unless otherwise stated), and so does the optional handset. 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.
