Change the battery

Replacing the SmartSensor battery involves gently prying off the battery cover, removing the dead battery, and replacing it with a new battery. Ensure that the positive side is facing up.

If you're having trouble removing the back cap or removing the battery, try using a small, thin tool such as a pen, plastic card, or a screwdriver to gently coax the cover off and lift the battery out.

Note: SmartSensor is incompatible with CR-2477N batteries.
