Southern hemisphere

 You need to input latitude and longitude of your location. Please refer to
your local weather observatory website. The latitude and longitude input affects
the sunrise/sunset time.

 Excepting the latitude and longitude, AUTO/DST (Daylight saving time)/ST
(Standard time) settings also affect the sunrise/sunset time. If AUTO is set, the
sunrise/sunset time follows the DST/ST setting of the RF clock data. If ST is set,
the sunrise/sunset time assumes standard time. If DST is set, the sunrise/sunset
time assumes daylight saving time.

MAINTAINANCE
Each sensor of this kit has a durable plastic casing that should retain its luster for
many years. It is better to do regular maintenance to keep the sensors with high
accuracy every half year. Do cleaning the casing only with a soft cloth slightly
dampened with water or a mild soap. Please use screw drivers or wrench to take
some parts off if necessary.
Te m p / h y g r o
sensor
Electrical storms can sometimes cause power surges harmful to electronic
equipment. For your own safety, take caution when using the main unit or doing
maintenance during storms.
To Maintain the Thermo/Hygro Sensor (THGN300)
1. Remove the rain collector from the rain gaug.
2. Unscrew the three type B screws from the
rain gauge.
3. Unscrew the three screws from the bottom
of the thermo/hygro sensor casing.
4. Take off the white sensor protective cap by
squeezing its two sides with some pressure.
5. Extract the inner cap and filter screen from
the outer cap.
6. Clean the filter screen and casing
with water.
7. Install all the parts until they are
entirely dried.

 If the temperature and humidity readings are still strange and inaccurate,
you need to consider replacing this sensor, please contacting our customer service
for the details.
