Your Floodie is designed to run for 2 years on a pair of AA batteries. To gain access to the battery compartment,
- use a coin to pry off the top cover,
- swap out the batteries, and
- snap the top cover back into place.
Be sure to line up the cover so that the gold contacts are on the bottom when you can read the Alert Labs logo. Upon inserting new batteries, the light will come on for several minutes. Make sure the light is green, which indicates you have a good signal.
