I moved earlier this month and misplaced my owner's manual packet. I have a C320 which lacks storage space for such a huge object. How do I encode the on-board remote door opener with the signal from the portable remote? I know what to do at the opener once I get the signal stored - i.e., have my wife climb on the ladder and press the "store" button while I press the on-board button. Thanks in advance for the info.
