Remove the battery door on the back of the sensor by sliding off the battery door. Insert two AA
batteries as shown in Figure 1, and close the battery door. Note that the temperature and humidity
will be displayed on the LCD display.
We recommend lithium batteries for cold weather climates, but alkaline batteries are sufficient for
most climates. We do not recommend rechargeable batteries. They have lower voltages, do not operate
well at wide temperature ranges, and do not last as long, resulting in poorer reception.

3.4 Mounting the Outdoor Thermo-Hygrometer Sensor
It is recommended you mount the remote sensor on a north facing wall, in a shaded area, at a height at
or above the receiver. Direct sunlight and radiant heat sources will result in inaccurate temperature
readings. Although the sensor is weatherproof, it is best to mount in a well protected area, such as an
eve.
Use a small nail or screw (included) to mount to a vertical surface, as shown in Figure 2.
