I get this error message everytime I change the 3 D cells. I then have to
take out the 2 AA's for the computer backup, wait a few minutes, then
re-install new D cells. Then I have lost all my memories and have to
re-program them. It's getting to be a pain! I turn the radio off and on
using the sleep function

I remember there being a mod for the battery tray to correct this but can't
remember? Any help would be appreciated.
