FCC Requirements

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

1. This device may not cause harmful interference, and

2. This device must accept any interference received, including interference that may cause
undesired operation.

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
h

erference in a residential installation. This equipment generates, uses, and can radiate

armful int
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 will
n

ot occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception which can be determined by turning the radio or television off and on, the user is
encouraged to try to correct interference by one or more of the following measures:

1. Reorient or relocate the receiving antenna.

2. Increase the separation between the equipment and receiver.

3. Connect the equipment into an outlet on another circuit.

4. Consult the dealer or an experienced radio/TV technician for help.

FCC REGISTRATION INFORMATION — Part 68

This equipment complies with Part 68 of the FCC rules and the requirements adopted by ACTA. On
the exterior of this equipment is a label that contains a product identifier in the format
US:AAAEQ##TXXXX. If requested, this information must be provided to your telephone company.

number of devices you may connect to your line, as determined by the REN, contact your local
telephone company. For product approved after July 23, 2001, the REN for this product is part of the
product identifier that has the format US:AAAEQ##TXXXX. The digits represented by ### are the
REN without the decimal point. (For example, 03 represents a REN of 0.3.) For earlier producers, the
REN is separately shown on the label.
