SERIAL NUMBER
DATE OF PURCHASE
Diamond Audio Technology, Inc. (DAT) warrants this amplifier to be free from defects in material and workmanship for the lifetime of the
amplifier in its original installation provided the amplifier was purchased from and installed by an authorized DAT retailer. Amplifiers
purchased from but not installed by an authorized DAT retailer carry a one (1) year parts and labor guarantee.
This warranty is not transferable and applies only to the original purchaser of this amplifier in its original installation. Original
purchaser must reside in the United States and register the amplifier with DAT within 30 days of installation. Warranty registration
information can be found at www.diamondaudio.com or by calling 866-328-2834. Original purchaser must be able to provide proof of
purchase and installation with the sales receipt from the authorized DAT retailer that sold and installed the amp.
Should a manufacturing defect occur in the first three (3) years of the above said warranty period, DAT will replace the defective product
with new product of the same or equivalent value and performance. Should the defect occur after the first three (3), DAT will (at its
discretion), repair or replace the defective product or parts with new or remanufactured product for as long as the amplifier is in its original
installation. Damage or failure caused by any of the following is not covered under this warranty policy: negligence, improper use, abuse,
product modification, unauthorized repair attempts, accident, acts of God, misrepresentations by DAT retailers, and improper/inadequate
packaging during return shipping.
Warranty is void if serial numbers have been removed, altered or defaced or if protective seal is broken.
In the event a DAT product should require service, you should visit the authorized DAT retailer you purchased the product from and they
can expedite your claim. All claims must fall into the guidelines listed above and be accompanied by a copy of the original sales and
installation receipt from that authorized DAT retailer.
Product returned for warranty service must be freight-prepaid, properly packaged and clearly marked with the Return Authorization (RA)
number issued by DAT. Any product returned to DAT that is improperly packaged, does not have a RA number clearly marked on the package,
or never received a RA number; may be refused upon delivery. DAT does not assume responsibility for lost or misdirected product.
Repair or replacement under this warranty is the exclusive remedy of the consumer. DAT shall not be liable for any incidental or
consequential damages for breach of any expressed or implied warranty on this product. Some states do not allow the exclusion or
limitation or incidental or consequential damages, or allow limitations on how long an implied warranty lasts, so the above limitations or
exclusions may not apply to you. This warranty gives you specific legal rights and you may also have other rights that may vary from state to
state.
Customers outside the United States should contact their local sales office to obtain information on pricing, exchange unit availability,
instructions, service and warranty/non-warranty replacement or repair.
