Limited Warranty and Limitation of
Liability
AT&T warrants to you, the customer, that your MERLIN LEGEND
Communications System will be in good working order on the date AT&T or
its authorized reseller delivers or installs the system, whichever is later
("Warranty Date"). If you notify AT&T or its authorized reseller within one
year of the Warranty Date that your system is not in good working order,
AT&T will without charge to you repair or replace, at its option, the system
components that are not in good working order. Repair or replacement
parts 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 remove the system and, at your option, refund the
purchase price of your system, or apply the purchase price towards the
purchase of another AT&T system.
If you purchased your system directly from AT&T, AT&T will perform
warranty repair in accordance with the terms and conditions of the specific
type of AT&T maintenance coverage you selected. If you purchased your
system from an AT&T-authorized reseller, contact your reseller for the
details of the maintenance plan applicable to your system.
This AT&T limited warranty covers damage to the system caused by power
surges, including power surges due to lightning.
