Dear Mr. Downs,
Thank you for contacting Pentax.
Any K20D purchased between October, 2008 and July 31, 2009 from an authorized Pentax dealer in the US qualifies for a free upgrade to the 3 yr. Pentax Extended Warranty. If you did not receive your warranty card from the dealer you can obtain one from Pentax by emailing (pentaxinfo@pentax.com) or faxing (919-501-7575) a copy of your dated proof of purchase (sales receipt, credit card statement, order confirmation, packing slip, etc.) along with your name and address to Pentax, Attn.: K20D Ext. Warranty. Upon receipt of your warranty card you will need to register your warranty control number with your name, address and camera's serial number by going to this website:
Pentax U.S.A., Inc. - Extended Warranty Registration
OR by calling the technical support center at the number below.
If you are in need of further assistance, please respond to this email or call our technical support center at 800-877-0155.
