PRODUCT REGISTRATION

Thank you for your recent purchase. Though not required to get the protection of the standard

warranty, registering your product is a relatively short process, and entitles you to additional

warranty protection, except that failure by California and Quebec residents to register their

product does not diminish their warranty rights. The duration of warranty coverages in Texas

differs in some cases.
For Product Registration, please register by following this link:
