MANUFACTURER'S 

DECLARATIONS 

LIMITED WARRANTY

This limited warranty applies to SE AUDIOTECHNIK® branded products.

The statutory warranty rights towards the seller are not affected by this 

guarantee. In fact, it justifies additional independent warranty claims 

towards SE AUDIOTECHNIK®.

SE AUDIOTECHNIK® warrants that the SE AUDIOTECHNIK® product 

purchased from SE AUDIOTECHNIK® or from an SE AUDIOTECHNIK® 

authorized reseller, is free from defects in materials or workmanship 

under normal use, for a period of three years from the date of purchase.

The limited warranty period starts on the date of purchase. To receive 

warranty services, proof of the purchase must be provided. The dated 

sales or delivery receipt, stating the date of purchase, is the proof of 

purchase. Should products of the brands named above be in need of 

repair within the limited warranty period, you are entitled to warranty 

services according to the terms and conditions stated in this document.

This limited warranty extends only to the original purchaser of this 

SE AUDIOTECHNIK® branded product and is not transferable to anyone 

who obtains ownership of the SE AUDIOTECHNIK® product from the 

original purchaser. During the limited warranty period, SE AUDIO-

TECHNIK® will repair or replace the defective component parts or the 

product. All component parts or hardware products removed under 

this limited warranty become the property of SE AUDIOTECHNIK®.

In the unlikely event that the SE AUDIOTECHNIK® product has a recur-

ring failure, SE AUDIOTECHNIK®, at its discretion, may elect to provide 

a replacement unit of SE AUDIOTECHNIK® choice that is at least 

equivalent to your SE AUDIOTECHNIK® branded product in hardware 

performance.

SE AUDIOTECHNIK® does not warrant that the operation of this 

product will be uninterrupted or error-free. SE AUDIOTECHNIK® is 

not responsible for damage that occurs as a result of your failure to 

follow the instructions included with the SE AUDIOTECHNIK® branded 

product.

This limited warranty does not apply:

to wear parts

to any product from which the serial number has been removed  

 

or that has been damaged or rendered defective as the result of  

 

an accident

in case of misuse, abuse, or other external causes

by operation outside the usage parameters stated in the user's  

 

documentation

by use of spare parts not manufactured or sold by 

 

SE AUDIOTECHNIK®

by modification or service by anyone other than 

 

SE AUDIOTECHNIK®

These terms and conditions constitute the complete and exclusive 

warranty agreement between the purchaser and SE AUDIOTECHNIK® 

regarding the SE AUDIOTECHNIK® branded product purchased.

LIMITATION OF LIABILITY

If the SE AUDIOTECHNIK® branded hardware product fails to work 

as warranted above, the sole and exclusive remedy shall be repair or 

replacement. SE AUDIOTECHNIK®'s maximum liability under this limited 

warranty is explicitly limited to the lesser of the price it has been paid 

for the product, or the cost of repair or replacement of any hardware 

components that malfunction in conditions of normal use.

SE AUDIOTECHNIK® is not liable for any damages caused by the product 

or the failure of the product, including any lost profits or savings or 

special, incidental or consequential damages. SE AUDIOTECHNIK® is 

not liable for any claim made by a third party or made by the purchaser 

for a third party.

This limitation of liability applies whether damages are sought, or 

claims are made, under this limited warranty or as a tort claim (including 

negligence and strict product liability), a contract claim, or any other 

claim. This limitation of liability cannot be waived or amended by any 

person. This limitation of liability will be effective even if the purchaser 

has advised SE AUDIOTECHNIK®, or an authorized representative of 

SE AUDIOTECHNIK®, of the possibility of any such damages.

This limitation of liability however, will not apply to claims for personal 

injury.

This limited warranty gives the purchaser specific legal rights. There may 

also be other rights that may vary from state to state or from country to 

country. The purchaser is advised to consult applicable state or country 

laws for a full determination of his rights.

REQUESTING WARRANTY SERVICE

To request warranty service for the product, the purchaser must contact 

SE AUDIOTECHNIK® or the SE AUDIOTECHNIK® authorized reseller from 

which the product was purchased.
