So how much time went by from the time it got wet until the time you took it apart and dried it ?
If that happened to my Pro-96, I would pull the batteries ASAP, open it up and dry it our the best I can
with compressed air, then leave it appart for a week easy to make darn sure it's completely dry !!!
Then re-assemble it and do a quick test and if a no RX/Scan, those batteries would STAY OUT
for weeks .... while I happily use my Pro-106

) Parts of the circuits take time to completely dry out !!!
BTW ~ Sail by your local RS and have them print you out a replacement parts list just for grins

Have the RS person go to RSU parts lQQkup and key in your Pro-96 catalog number 200-0526
You will probably be shocked at all how expensive the main logic boards can cost !
Again, consider sending it in for repair only AFTER it still doesn't work after a few weeks !!!
Good luck, and remember, an RS repair estimate of $20 is probably a GREat deal considering the $$$
Speaking of dollars, have your local RS perform a simple "Product Availibility" District and Region wide
for a Pro-96 because you just might get lucky and find a new one on clearance for $200.97, heck just
2 of the main logic boards are something like $250 ish and $219 ish +/-. Even cQQler would
be if RS could find you a very deep clearenced Pro-2096 ( 200-0496 ) at some store still for ONLY $29.97 ...
I know I have lQQked in my RS region and they are all snapped up - imagine that

PS ~ Tell me that you did try to insert a paper clip in the little hole above the AC-Adaper plug
side of the scanner right next to the rubber hand grip to see if by some miracle a reset will work ?
