Irish Mist II,
I spoke with Furuno and as they recommend that you take it to a qualified Furuno Service Dealer but they did send me a page out of the service Manual with the directions. I have tried attaching the directions for switching the belt for a 1623 which is the most common dome that needs the belts changed. However the file is two large to attach on THT. The instructions are pretty much the same for most of there radars as well and appear to be a pretty simple switch. If you want you can call me, email me, or reply to this thread with your email address I will be happy to send you these instructions. Please let us know if there is anything else we can assist you with.
Thanks,
Steven Waters
