To Insert or replace the battery in the Smart Probe, first remove the battery cover from the probe using a coin or a standard (flathead) screwdriver. Insert a new CR2450 battery making sure the positive end of the battery faces out. Finally, screw the battery cover back in until it's fully seated.
Note: If the battery cover is not fully seated, water moisture may be able to penetrate the battery chamber and damage to the probe may occur.
