Last night I knocked my BC250D into the bathroom sink, it got submerged maybe 2" and I yanked it out right away. I took a hair dryer and held the scanner upside down and blew the water out of the speaker and tried to get as much out of the key board. It turns on but will switch back between banks 1 and 2 even though I only monitor bank 2 now. None of the keys seems to work, the back light, etc. Is my scanner ruined? Can I take the back off and leave it out in the sun for a day to try to dry it out?
