2.1 How to Power the Thermometer
2.1.1 Battery Operation
Invert the thermometer and install 4 fresh AA size batteries as shown in
Figure 2-1. Make sure the batteries’ polarities are correct, the batteries are
not put in backwards, and are of the same type.
If the icon flashes, the batteries must be
replaced with fresh batteries immediately.
