LabQuest is designed to be splash-resistant, but is not waterproof. If the unit is immersed or gets very wet, permanent damage can result. Such damage is not covered by the LabQuest warranty. If your LabQuest unit has gotten wet and now it behaves strangely or won't turn on, here are a few steps you can try:
1. Remove the battery as soon as possible. Follow these instructions:

2. Give the unit up to a week to dry out. There are a few tricks you can try to remove moisture from the unit. The "rice trick" is rumored to help: Place the unit in a plastic bag and fill it with dry rice grains. Seal the bag and store the unit in a warm, dry place. The silica packets, such as those found in the boxes of new shoes, are also good for absorbing moisture.
We have seen cases where the above steps have helped revive a unit that was damaged by water. These may not help now, but to prevent something like this form happening again, you may want to see some options for protecting the LabQuest from getting wet in the first place:
