The TestLobe lets you check whether your batteries are working. It also serves as a battery compartment.
To check your batteries, place them in the TestLobe one at a time. Slide the battery onto the gold portion of the tester with the “+” sign facing up.
A smiley face or check mark indicates that the battery is good. A sad face or “x” indicates that the battery needs to be changed.
