Hold the tester in your hand and you will see the on/off switch at the end of the tester. Make certain that the tester is turned to "off" and just below the word "off" you will see a small white dot. You will need to depress the white dot and while doing so turn the top part of the on/off switch toward that white dot. At the same time you will also need to pull that cap upward, like you would be pulling it off the tester, and you will see that it slides up and off. That is where the two AAA batteries are located!! Re-installing it is just the opposite of removing it.
