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.

3.5 Mounting the Outdoor Thermo-Hygrometer Sensor
It is recommended you mount the remote sensor on an outside 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 11.
