consumer purchaser that, except for limitations and exclusions set forth below, this product shall
be free from defects in materials and workmanship for a period of one (1) year from the date

at Clarity’s option, without charge, of any part or unit that proves to be defective in material or

Exclusions from Warranty: This warranty applies only to defects in factory materials and
factory workmanship. Any condition caused by accident, abuse, misuse or improper operation,
violation of instructions furnished by Clarity, destruction or alteration, improper electrical voltages
or currents, or repair or maintenance attempted by anyone other than Clarity or an authorized

types of equipment and Clarity does not warrant that its equipment is compatible with the equip-
ment of a particular phone company.
Implied Warranties: Under state law, you may be entitled to the benefit of certain implied
warranties. These implied warranties will continue in force only during the warranty period. Some
states do allow limitations on how long an implied warranty lasts, so the above limitation may not
apply to you.
Incidental or Consequential Damages: Neither Clarity nor your retail dealer or selling
distributors has any responsibility for any incidental or consequential damages including without
limitation, commercial loss or profit, or for any incidental expenses, expenses, loss of time, or

REGULATORY COMPLIANCE
Part 15 of FCC Rules Information
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.
Your equipment has been tested and found to comply with the limits of a Class B digital device,
pursuant to Part 15 of FCC rules. These limits are designed to provide reasonable protection against
harmful interference in 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 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
equipment off and on, you are encouraged to try to correct the interference by one of the following
measures:
1. Where it can be done safely, reorient the receiving television or radio antenna.
2. To the extent possible, relocate the television, radio or other receiver with respect to the
telephone equipment. (This increases the separation between the telephone equipment and the
receiver.)
3. Connect the telephone equipment into an outlet on a circuit different from that to which the
television, radio, or other receiver is connected.
4. Consult the dealer or an experienced Radio/TV Technician for help.
WARNING: Changes or modifications not expressly approved by the manufacturer responsible for
compliance could void the user’s authority to operate the equipment.

appropriate electrical inspection authority, or electrician, as appropriate.

a) This equipment complies with Part 68 of the FCC rules and the requirements adopted by the ACTA.
On the bottom 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 the telephone
company.
b) A plug and jack used to connect this equipment to the premises wiring and telephone network must

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 the 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 (e.g., 03 is a REN of 0.3). For earlier
products, the REN is separately shown on the label.
d) 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 telephone company will notify the customer as soon as possible. Also, you will be
advised of your right to file a complaint with the FCC if you believe it is necessary.
e) The telephone company may make changes in its facilities, equipment, operations or procedures
that could affect the operation of the equipment. If this happens the telephone company will provide
advance notice in order for you to make necessary modifications to maintain uninterrupted service.

contact Clarity, 1-800-426-3738. If the equipment is causing harm to the telephone network, the
telephone company may request that you disconnect the equipment until the problem is resolved.
g) This telephone equipment is not intended to be repaired and it contains no repairable parts. Opening
the equipment or any attempt to perform repairs will void the warranty. For service or repairs, call
1-800-426-3738.
h) Connection to party line service is subject to state tariffs. Contact the state public utility
commission, public service commission or corporation commission for information.
i) If your home has specially wired alarm equipment connected to the telephone line, ensure the
installation of this telephone equipment does not disable your alarm equipment. If you have questions
about what will disable alarm equipment, consult your telephone company or a qualified installer.
j) This telephone equipment is hearing aid compatible.
Customer-Owned Coin/Credit Card Phones:
