bc560xlt

Hi i have an old uniden bearcat bc560xlt that i picked up from rarsfest for a dollar and the radio itself works after swapping the antenna connector from din to so239 and attaching an external speaker but once i program in channels after a few minutes all the channels are programmed to 00.000...

Hello, I am trying to delete a stored frequency in my BC560XLT scanner or, do a master reset and delete. Could someone please help me with this process? I tried reprogramming over the channel with 000.000 then E, but it doesn't reprogram to a cleared channel and frequency. All help is greatly...
