I allowed my battery to drain, causing the radio to display CODE. I
_thought_ I knew the code it wanted, and attempted it and a couple of
variations, all of which were wrong. Now, I have the code card, but the
radio will not accept any entry. I know the code I have is the right one,
and I'm certain that I tried too many codes from my memory, and set off some
sort of counter. How do I erase the code counter that disables the radio if
too many codes are input? My gut instinct is that if I disconnect the
battery for a while, it should do the trick. Any thoughts?
