Frank,

It sounds like the MCU is getting "mixed up".  Try doing a Reset to
Factory Defaults.
See page 69 in the manual.  It is a 2 step process.
1) Hold BAND and MENU together and power on - release the buttons after
the LED test.  E09 should be displayed.
2) Turn power off, then back on and you should see E10.  Tap any switch.
