I have a Realistic 20-400 Pro-58 Scanner and the last few months it has been losing programming?
Not when it is turned off, but even when it is left on, all the channels go blank. Does this model have an internal battery for memory backup? Thanks for you help.

Most programmable scanners use a eprom chip that keeps the memory. There may be an issue with the eprom chip.
