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 not 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.

FCC REGISTRATION INFORMATION — Part 68
This equipment complies with Part 68 of the FCC rules and the requirements adopted by ACTA. On the exteri-
or of this equipment is a label that contains a product identifier in the format US:AAAEQ##TXXXX. If request-
ed, this information must be provided to your telephone company.
A plug and jack used to connect this equipment to the premises wiring and telephone network must comply
with the applicable FCC Part 68 rules and requirements adopted by ACTA. A compliant telephone cord and

The REN is useful to determine the quantity of devices you may connect to your telephone line. Excessive
RENs on a telephone line may result in the devices not ringing in response to an incoming call. In most, but
not all areas, the sum of the RENs should not exceed five (5.0). To be certain of the 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.
If this telephone equipment causes harm to the telephone network, the telephone company will notify you in
advance that temporary discontinuance of service may be required. But if advance notice isn’t practical, the

complaint with the FCC if you believe it is necessary.
The telephone company may make changes in its facilities, equipment, operations, or procedures that could
affect the proper functioning of your equipment. If they do, you will be notified in advance in order for you to
make necessary modifications to maintain uninterrupted service.

disconnect the equipment until the problem is resolved.
DO NOT DISASSEMBLE THIS EQUIPMENT: it does not contain any user serviceable components.
We recommend the installation of an AC surge arrester in the AC outlet to which this equipment is connected.
Telephone companies report that electrical surges, typically lighting transients, are very destructive to cus-
tomer terminal equipment connected to AC power sources.
