LIMITED WARRANTY STATEMENT

       Diamond Audio Technology, Inc. (DAT) warrants all DAT products to be 
free of defects in material and workmanship for a period of one (1) year from
the date of original purchase provided they are purchased from an authorized 
DAT retailer in the United States.  However, the effective warranty period will 
be three (3) years if the products were purchased from and installed by an 
authorized DAT reta il er.

 

       What is covered: Parts and labor to effect repair or, at the sole discretion 
of DAT, replacement of either any malfunctioning or defective part(s) or the 
entire system should the system or any component part(s) thereof fail to
perform as designed.  Includes return freight via ground transportation to 
destinations within the United Stat e

 s .

 

 

       What is NOT covered: Installation or setup and repair or replacement  of 
the system or any parts thereof which, in DAT's judgment, fail or become 
damaged as a result of negligence, improper use, abuse, unauthorized 
modification or service, improper or inadequate packaging during shipment, 
installation by a non-authorized dealer, accident, or use for any purpose 
other than those for which this product was originally intended, or where the 
model's serial  number  has  been r emoved, al tered or def aced.

       Who is covered: Original purchaser so long as they reside in the United 
States and can provide proof of the original date of purchase 
( e . g . ,   s t o r e r  e c e i p t ) f  r o m a n  a u  t h o r i z e d D A  T r e t a  i l e r .

OUTSIDE THE U NITED STAT ES

 

       Customers outside the United States should contact their local sales 
office to obtain information on prices, exchange unit availability, instructions, 
serv ice and warran ty/non-warrant y repairs.

 

       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.  
Except to the extent prohibited by applicable law, any implied warranty of 
merchantability or fitness for a particular purpose on this product is limited 
in duration to the duration of this warranty. Some states do not allow the 
exclusion or  limitation of 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.

HOW TO OBTAIN WARRANTY SERVICE

       In the event a DAT product should require servicing, you 
should (a) visit an authorized DAT retailer or (b) call the DAT 
Service Dept. at  (866) 328 2834.  To be eligible for warranty 
service within a three (3) year period, the accompanying 
receipt of original purchase from an authorized DAT retailer 
must specifically note that dealer installation was provided.

       Product returned for repair/service must be properly 
packaged and clearly marked with the Return Authorization 
(RA) number issued by DAT. If the RA number is not clearly 
marked on the package or no RA number was issued by DAT, 
the product may be refused upon delivery. DAT does not
