Registering your extended warranty is not required. If you made your purchase through the official Echelon website, simply keep your order number in a secure place, as you may need to provide it in the event of a warranty claim. If you bought the product elsewhere, please retain your receipt and be prepared to provide a copy if necessary. In the event that you no longer have the original receipt, you can use the email address that you used to register your Echelon account as proof of membership.
