    Part 68
    This equipment complies with Part 68 of the FCC rules and the requirements adopted by the Administrative Council for 
    Terminal Attachments (ACTA). On the back of this equipment is a label that contains, among other information, a product 
    identifier in the format US:AAAEQ##TXXXX. If requested, this number must be provided to your telephone company.
    This equipment uses the RJ-11C Universal Service Order Code (USOC) jack.
    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 the ACTA. A compliant telephone cord and modular plug is 
    provided with this product. It is designed to be connected to a compatible modular jack that is also compliant. See the 
    Setup Sheet for more information.
    The Ringer Equivalence Number (REN) is used to determine the number of devices that may be connected to a 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 RENs should not exceed five (5.0). To be certain of the number of devices that may be connected 
    to a line, as determined by the total RENs, contact your local telephone company. For products 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 a decimal point (for example, 03 is a REN of 0.3). For earlier products, the REN is 
    shown separately on the label.
    If this equipment causes harm to the telephone network, the telephone company will notify you in advance that temporary 
    discontinuance of service may be required. If advance notice is not practical, the telephone company will notify the 
    customer as soon as possible. You will also be advised of your right to file a complaint with the FCC.

    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 (Underwriters 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.
    The Telephone Consumer Protection Act of 1991 makes it unlawful for any person to use a computer or other electronic 
    device, including fax machines, to send any message unless said message clearly contains in a margin at the top or bottom

    business or other entity, or other individual sending the message, and the telephone number of the sending machine or 
    such business, other entity, or individual. (The telephone number provided may not be a 900 number or any other number
