I've had my RX65 for almost 10 months but recently I got a weird error where it would blink SelfCal4 a couple of times then Service Required after it repeatedly. I tried what T-T had mention in another post...
This didn't do anything... just some almost undetectable weird "click" sound, and it didn't even turn on. I discovered if I hold "City" and "BRT" and turn on the detector it would reset. But after a few seconds of being on, it would display the same error.You should reset your RX-65 if you're holding buttons "City" "BRT" and "Mute" while you turn on the detector.
Also, If I end up having to send my unit back to Beltronics, you think they will "flash upgrade" the unit? providing that it is even upgradeable?
