I attempted to register my radio. When it came to the serial number question, I typed it in as it's shown on the BCDX436HP screen--a 5-digit number, a dash, a 9-digit number, another dash, and three more digits. When I looked it up later in the "My scanners" section, the serial number displayed bore little resmeblance to what I entered. There was no checksum, what I entered was truncated, and different digits appeared. What'd I do wrong, and how can it be corrected since there's no way to change that field on the registration screen? Should I just put in a new one and attempt to delete the old one?
