CS:
take the batteries out of it and place it in the top rack of your dishwasher ... no detergent, no heat dry ... send it through the NORMAL cycle ... then remove it and shake as much excess water from it as you can, and then let it dry thoroughly for a few days ... even placing on top of a gentle heat source.
(remember to put the batteries back in before you try to sync it!)
Your Welcome!
