Hi I have an MX800. It was a few years old and worked ok. I was updating the programming (with new MX-700 editor), and I got an error in the transfer. I noticed the batteries were low and the usual programming on the LCD was not there. I put in new batteries, and the thing just keeps "testing". Everything is ok, the last LCD says "skipped", and then it repeats itself. I can't get it to connect to the editor b/c it keeps testing. Any ideas?
