Finally my Uniden BCD436HP scanner has come across...
"Clock Settings have been lost." like above.
I own two BCD436HPs and one of them always works through 24hrs using USB cable. The other had been shutting down for 1month. That is it! After that, now, the problem has been encountered. I have a feeling the BCD436HPs that RTC problem not updated should be powered on every 1week at least. In addition, my BCD436HP had not used up the batteries yet.
The time has come! It seems to have to apply for "REAL-TIME CLOCK BATTERY REPAIR CAMPAIGN"..... at last. This is my TURN.
OK, I have filled out the application form and submitted. Come on, Uniden's reply!
