System Dead Due to Power Failure
PARTNER telephones do not work during a power failure— you must use a standard touch-tone or rotary telephone.
For more information about setting up your system for a power failure, see p. 2-3.
The PARTNER system has an internal power supply that allows it to maintain its system settings for approximately
100 hours (four days) after it stops receiving power. After 100 hours elapse, all of the systems settings return to
the factory settings.

							Maintenance
Your PARTNER system is designed to provide trouble-free performance without
any special maintenance procedures. However, there are a few precautions
you can take to prevent accidental damage to your system.
206 Modules
To prevent damage to the 206 modules:
n
n
n
nKeep the modules in an area free of dust, smoke, and moisture.
Do not block the air vents by placing objects on top of the modules.
Place the modules in a place with a temperature between 32 degrees and
104 degrees Fahrenheit.
Do not place the modules in direct sunlight.
WARNING: There are no user-serviceable parts inside the modules or
module connector. Hazardous voltages within. DO NOT OPEN!
Telephones
n
n
n
To prevent damage to telephones:
Do not place your telephones near a heating duct, radiator, or other heat
source.
Do not drop your telephones or expose them to excessive shock or vibration.
Unplug the telephone if:
nIts cord is damaged
nLiquid is spilled into it
nIts housing becomes cracked or otherwise damaged.
To clean your telephone, wipe the outside housing with a soft, dust-free cloth. If
absolutely necessary, you may clean it with a soft cloth slightly dampened with a
mild soap and water solution. Dry quickly with a soft cloth.
CAUTION: Your telephone contains sensitive electronic parts. Never
submerge it in any kind of liquid, and never use detergents, alcohols,
solvents, abrasive cleaners, or an excessive amount of water when
cleaning the housing and faceplate. To do so could result in irreparable
damage.

Warranty and Post-Warranty Repair
In Warranty RepairsIf you obtained your PARTNER system directly from AT&T, AT&T will repair your
system free of charge during the one-year warranty period, subject to the limita-
tions of the warranty. Simply call the Helpline at 1 800 628-2888 to ask for ser-
vice. If you purchased your system through an AT&T-authorized dealer, contact
your dealer for repairs.
Business-Day service is standard during the warranty period for both the 206
modules and PARTNER phones. Business-Day service is performed during nor-
mal business hours. However, if you need 24-hour service protection during the
warranty period on the 206 modules in case there is a major system failure, you
can purchase an Around-the-Clock service contract from your local AT&T sales
office (1 800 247-7000).
Post-Warranty RepairsIf you purchased your system from AT&T and you have a post-warranty service
contract, AT&T service is provided under the terms of that contract.
If you do not have a contract, AT&T service is provided on a time-and-materials
basis by calling the Helpline at 1 800 628-2888. (Around-the-Clock service is
not available for phones.)
To eliminate unexpected repair costs after the warranty period, you can pur-
chase a post-warranty service contract from AT&T. A contract entitles you to
unlimited service calls with no charge for parts and labor, plus preferred
dispatch priority. Both Business-Day and Around-the-Clock coverages of vary-
ing lengths are available. To order a post-warranty service contract, please call
1 800 247-7000, or contact your AT&T-authorized dealer.
If you leased your system from AT&T, Business-Day service is included in your
lease. To upgrade to Around-the-Clock service, call 1 800 247-7000.
If you purchased or leased your system through an AT&T-authorized dealer,
contact your dealer for repairs.

							AT&T Limited Warranties
Commercial UseThe following AT&T limited warranty and limitation of liability will apply if you
have purchased your PARTNER Communications System (System) primarily
for commercial purposes.
AT&T Commercial Warranty
AT&T warrants to you that your System will be in good working order when you take title and that it will remain in good
working order for a period of one year (the warranty period) or AT&T will, at its option, repair or replace the system com-
ponent that is not in good working order. Any repair or replacement components may be new or refurbished and will be
provided on an exchange basis. If AT&T determines that your System cannot be repaired or replaced, AT&T will refund
the purchase price of the System to you. If you purchased your System directly from AT&T, AT&T will perform warranty
repair on your premises in accordance with the terms and conditions of AT&T’s Business Day or Around the Clock
warranty plans. The details of AT&T’s warranty plans may be obtained from AT&T by calling 1 800 247-7000. If you pur-
chased your System from an AT&T-authorized dealer, you will be covered by AT&T’s Authorized Dealer Warranty Plan
during the warranty period. Contact your Authorized Dealer for details of AT&T’s Authorized Dealer Warranty Plan.
AT&Ts obligation to repair, replace, or refund as set forth above is your exclusive remedy.
The limited warranties provided above do not cover damages, defects, malfunctions or product failures caused by:
n    Failure to follow AT&T’s installation, operation, or maintenance instructions;
n    Unauthorized modification or alteration of the System or its components;
n    Product abuse, misuse, or the negligent acts of persons not under the reasonable control of AT&T;
n    Actions of third parties and acts of God other than power surges (e.g., lightning).
This warranty applies to a System purchased directly from AT&T or purchased directly from an authorized AT&T Dealer.
Except as specifically set forth above, AT&T, its affiliates, suppliers, and dealers make no warranties, express or implied,
and specifically disclaim any warranties of merchantability or fitness for a particular purpose.
Except for personal injury, the liability of AT&T, its affiliates, suppliers, and dealers for any claim, loss, damage, or
expense from any cause whatsoever regardless of the form of the action, whether in contract, tort, or otherwise, shall not
exceed the lesser of direct damages proven or the repair or replacement cost of the System or the System’s purchase
price. In no event shall AT&T, its affiliates, suppliers, or dealers be liable for incidental, reliance, consequential, or any
other indirect loss or damage (including lost profits or revenues) sustained or incurred in connection with the System.
This limitation of liability shall survive failure of the exclusive remedy set forth in the limited warranty above.
