running or attached to a load: Press the battery test button and observe the color of the battery

indicator light (note that the buzzer sounds, also, if the button is held more than a few seconds).

2) While continuing to press in, press up on the battery holder. The battery tray should slide out

easily.

4) Install a new 9-volt battery, matching the polarity marked on the battery with the polarity

marked on the tray.
