Indoor Thermo-Hygrometer Assembly
Remove the battery door on the back of the sensor, as shown in Figure 1. Insert two AAA (alkaline
or lithium, avoid rechargeable) batteries in the back of the indoor sensor.
We do not recommend rechargeable batteries because they start at a lower voltage and do not last as
long, resulting in wireless transmission issues.
