To obtain service for your ZT product:

Your dealer should be your first contact if you experience technical problems with your ZT product. Contact your 

dealer with a specific description of the problem, and have your purchase receipt available for purchase date proof 

(this will determine if your product is within ZT’s warranty coverage period). Your dealer will contact ZT and make 

arrangements for repair or replacement of your product. 

If your product is not within warranty period, you will be advised of repair charges.

Limited Warranty

ZT Amplifiers, Inc., warrants that the ZT product you have purchased shall be free of defects in parts and 

workmanship if used under normal operating conditions for a period of one (1) year from the date of purchase. 

This limited warranty shall run to the original purchaser when purchased from an Authorized ZT Dealer and any 

transferee of a retail purchaser. This limited warranty covers normal use of the ZT product only, and does not cover 

damages caused by misuse, abuse, accidents, or unauthorized service or parts.

IMPORTANT: PLEASE RETAIN YOUR SALES RECEIPT, AS IT IS YOUR PROOF OF PURCHASE COVERING 

YOUR LIMITED WARRANTY. TO TRANSFER THE WARRANTY TO A SUBSEQUENT PURCHASER, YOU MUST 

ENDORSE THE SALE OF THE PRODUCT TO THE SUBSEQUENT PURCHASER ON THE FRONT OF THE 

SALES RECEIPT. THIS LIMITED WARRANTY IS VOID WITHOUT SUCH ENDORSED SALES RECEIPT.

Defective products that qualify for coverage under this limited warranty will be repaired or replaced, at ZT’s 

discretion, with a like or comparable product, without charge. The ZT Amplifiers Dealer from whom you purchased 

your product may be authorized for warranty service, and should be your first point of contact when service is 

required. To receive warranty service from ZT Amplifiers, you must contact ZT Amplifiers by email during the 

warranty period at [email protected] to explain the defect and to obtain an RMA number (return 

materials authorization number), then return the complete product (in original packaging, if available) to an 

Authorized ZT Amplifiers Service Center, with proof of purchase, during the applicable warranty period. You are 

responsible for shipping the defective product to the Service Center. Return shipment will be provided at no cost to 

you; provided, however, that if you are located in a country other than the United States of America, then you will 

be responsible for all customs duties, VAT and other associated taxes and charges applicable to the shipment of 

the product. Any repair or service performed by any person or entity other than an Authorized ZT Amplifiers Service 

Center is not covered by this limited warranty. This limited warranty becomes void if the serial number on any 

product is defaced or removed, or the product has been damaged by alteration, misuse, accident, or neglect; or the 

product has been repaired or serviced  by persons not authorized by ZT Amplifiers.

THE PRODUCTS AND IS MADE EXPRESSLY IN LIEU OF ALL OTHER WARRANTIES EXPRESS OR IMPLIED. 

Any implied warranties, including, without limitation, any implied warranties of merchantability or fitness for any 

particular purpose, imposed under the law of any applicable jurisdiction are limited to the duration of this limited 

warranty.
