This equipment has been tested and found to comply with the limits for a CLASS B digital device
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can
radiate radio frequency energy, and if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that

interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.

all areas, the sum of the RENs of all devices connected to one line should not exceed five (5.0).
To be certain of the number of devices you may connect to your line, as determined by the total
