IMPORTANT: Make sure to observe the correct polarity when inserting batteries. The "+" markings on the batteries must line up with the diagrams inside the
battery compartments. Inserting the batteries incorrectly may result in permanent damage to the units. During the initial setup process, place the
wireless weather station and the outdoor sensors on a surface with 5-10 feet between each sensor and the weather station. Only use Alkaline batteries,

rechargeable batteries may not work:

STEP 1: Complete initial setup on a table with all components within 10 feet of each other.

STEP 2:

• It is important to allow sufficient light to reach the solar panel while activating the wind sensor. Make sure the lights are on in the
setup room and the solar panel is facing a 60W light bulb or brighter.
Ensure the solar panel is not covered

the reset hole.

• Use the provided plastic reset rod to gently press the reset button once

STEP 3: Insert two "AA" size batteries into rain sensor with correct polarity.

STEP 4:

• Insert two "C" size batteries into the thermo-hygro sensor with the correct polarity.

Note: Allow all sensors to run for two minutes before inserting batteries in the weather station.

STEP 5:

• Insert three "C" size batteries into the wireless weather station with the correct polarity.

transmission was successful. A wind speed or rainfall amount that reads "0" does not mean reception failure. It means that there was no wind or rain at the
time of the last measurement. The thermo-hygro sensor syncs with the wind and rain sensors and sends all outdoor sensor data to the weather station. The
thermo-hygro sensor tries for 4 minutes to sync to the wind sensor and then 4 minutes for the rain sensor. If not successful within 4 minutes, the thermo­hygro sensor will stop looking for the other sensors.
