As many others are having a clock issue with their BCD536HP, I am also having same issue and my scanner also freezes up to the point where I try to shut it off and it wont even respond. it has nothing to do with squelch settings and I have tried just about all that I know any suggestions or has this happened to anyone else? I submitted an email to uniden repair and they sent me an email with a ups ship label but when I fill it out it and try to print it says the shippers shipper number cannot be used for the shipment!
