to be connected to a telephone interface. The terminus of an interface may consist of any
combination of devices, subject only to the requirement that the sum of the RENs of all the devices
does not exceed five. The modem REN is located on the rear of the equipment on the product

Telephone companies report that electrical surges, typically lightning transients, are very destructive
to customer terminal equipment connected to AC power sources. This has been identified as a major
nationwide problem. It is recommended that the customer install an appropriate AC surge arrestor in
the AC outlet to which this device is connected. An appropriate AC surge arrestor is defined as one
that is suitably rated, and certified by UL (Underwriter’s Laboratories), another NRTL (Nationally
Recognized Testing Laboratory), or a recognized safety certification body in the country/region of
use. This is to avoid damage to the equipment caused by local lightning strikes and other electrical
surges.
