QUICK SETUP
Hint: Use good quality Alkaline Batteries; avoid rechargeable batteries.
1. Have the Wireless Weather Station and thermo-hygro sensor 3 to 5 feet
apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the thermo-hygro sensor first and next into the
Wireless Weather Station.
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the Wireless Weather Station and the thermo-hygro sensor will begin to
communicate with each other, and the display will show both the indoor temperature
and an outdoor temperature. If the Wireless Weather Station does not display both
temperatures after the 15 minutes, please retry the set up as stated above. After both
indoor and outdoor temperatures are displayed for 15 minutes you can place your
thermo-hygro sensor outdoors, and set your time.
The thermo-hygro sensor should be placed in a dry, shaded area (ex: under the eve of
a roof). The thermo-hygro sensor has a range of 330 feet. Any walls that the signal will
have to pass through will reduce distance. An outdoor wall or window will have up to 20
feet of resistance and an interior wall will have up to 10 feet of resistance. Your
distance plus resistance should not exceed 330 feet in a straight line.
NOTE: Fog and mist will not harm your thermo-hygro sensor, but direct rain must be
avoided.
