Notice to users of the Canadian telephone network
This product meets the applicable Industry Canada technical specifications.
The Ringer Equivalence Number (REN) is an indication of the maximum number of terminals allowed
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 labeling.
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.
This equipment uses CA11A telephone jacks.
