Warranty Information

All Pass Laboratories products purchased new from an authorized 
Pass Laboratories dealer in North America are covered by a 
transferable, limited 3-year warranty.  

This warranty includes parts and labor charges incurred at the repair 
facility.   Consequential damages are specifically not covered and 
damage due to modification or physical abuse is also not covered.

The customer assumes responsibility for shipping and insurance to 
and from the factory, or a factory specified repair facility.

Non-North American customers should consult with their original 
Pass Labs dealer or distributor for warranty repair instruction prior 
to contacting the factory or shipping product for repair.  Non-
North American product must be returned to the country of  origin 
for warranty service.  Foreign distributors are only required to 
offer warranty service on Pass Laboratories product that they have 
imported.  

Conditions of  warranty service and customer rights for product 
purchased outside the United States may vary depending upon the 
distributor and local laws.  Please check with your local distributor 
for specific information.

Any modifications to Pass Laboratories products that have not 
received written factory approval nullify all claims and void the 
warranty.  Should a modified product be returned to the factory for 
repair the owner will be required to pay all necessary charges for the 
repair in addition to those charges required to return the product to 
its original configuration.

In the case of  safety issues, no product shall be returned to the 
customer without those safety issues being corrected to the most 
recent accepted standards.

Removal or alteration of  original Pass Labs serial numbers voids the 
factory warranty.  Product with altered or missing serial numbers 
will be suspected as counterfeit product.  Pass Laboratories will not 
repair or in any way indemnify any counterfeit or cloned product.

Pass Laboratories does not offer products in voltages intended for 
international markets either to authorized Pass Labs dealers or to 
third parties located in the United States or Canada.
