I don't know about Parker but many bows today require no registration so supply a card. You may need your sales receipt. In your case, being as you bought the bow at Cabelas I would call Parker CS first and see what they say. The particular Cabelas you bought from may or may not have anybody working there who knows what they are doing. Parker CS should tell you your next step.
