Reference your need to find your radio's code
1. Go to Renntech at this web address:
RennTech.org Forums
2. You may need to join the forum.
3. Scroll down to the 986 section, specifically 986 Series. You will see Lost Radio Code - Post Your Request Here. Click on that link and provide your radio serial number.
4. Loren will give you one or two possible codes.
5. When I purchased a replacement CDR-220 (I only paid $85.00, but it did not come with the code), I used Renntech and Loren provided the code.
Good Luck
