warranty is void if the product’s serial number has been removed or defaced. 

Any applicable implied warranties are limited in duration to the period of the express warranty as 

provided herein beginning with the date of the original purchase at retail, and no warranties, whether 
express or implied, shall apply to this product thereafter. Some states do not allow limitations on implied 
warranties, therefore these exclusions may not apply to you. This warranty gives you specific legal rights,
