4.2 Outdoor Thermo-hygrometer Sensor Set Up
Note:
To avoid permanent damage, please take note of the battery polarity before inserting the
batteries.
Remove the battery door on the back of the sensor. Insert two AA batteries.
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.
Replace the battery door. Note that the temperature and humidity will be displayed on the LCD
display. Looking at the back of the unit from left to right, the polarity is (-) (+) for the top battery
and (+) (-) for the bottom battery.
Note:
the humidity is only displayed on outdoor thermo-hygrometer sensor
