My detector has gone into self cal a couple times before but this time after it went into self cal, it finished by flashing Service Required. I got the detector from Roy about 2 or 3 years ago so its out of warranty, but it is a legitimate, none ebay detector. I believe that it is Revb 6.1 or something in that range, ill check later.
anything that can be done on my end? or should i just call up bel and get a service number and send it in to get serviced.
