OWNER’S MANUAL
The Weather Station is equipped with a variety of functions
to provide comprehensive weather information. The receiver
unit has a clear, easy-to-read display that shows the
weather forecast, minimum/maximum indoor and outdoor
temperature and moon phase, as well as the time and date.
The Weather Station is able to receive and display readings
from remote sensors. The 433 MHz technology means
no wire installation is required and sensors can be placed
anywhere you like. With the radio controlled function, the
current time and date are automatically synchronized with
the time signal transmitted from Germany (DCF77) / UK
(MSF) / USA (WWVB). The signal can cover a distance of
about 932 miles (1500 km) from the related transmitter.

battery door.
Insert 2 AA size batteries into the battery compartment.2.
Make sure you insert them the right way according3.
to the polarity information marked on the battery
compartment.
Close the battery door.4.
NOTE:
Once the channel is assigned to one transmitter, it can only
be changed by removing the batteries or resetting the unit.
Avoid placing the transmitter in direct sunlight, rain or snow.
WEATHER STATION RECEIVER

Close the battery door.2.
Press the “RESET” key to re-start the clock and it3.
will automatically synchronize to the channels of the
transmitter.
NOTE:
The building material and the position of the receiver and
transmitter affect the effective range. Try multiple locations

12
to obtain the best result. Place the units away from metal
objects and electrical appliances to minimize the
interference. Position the receiver and transmitter within the
effective transmission range: 98 feet (30 meters) in usual
circumstances.
ABOUT THE WEATHER INDICATOR
The built-in barometer detects atmospheric pressure chang-
es. Based on the data collected, it can predict the weather
conditions in the forthcoming 12-24 hours.
NOTE:
The accuracy of a general pressure-based weather•
forecast is about 70% to 75%.
The weather forecast is meant for next 12 to 24 hours.•
It may not necessarily reect the current situation.
The weather forecast becomes stable after powering up•
for 24 hours.
If the clock location is changed due to altitude change•
(e.g. from low altitudes to high altitudes or vice versa),
please use a pin to press the “RESET” key to reset the
main unit and outdoor sensor.
The “Sunny” icon can only appear from 6 AM to 8 PM. If•
the weather is Cloudy/Rainy/Stormy during this period,
the “Sunny” icon may not appear.
The “Moon phase & Star” icon can only appear from•
8 PM to 6 AM. If the weather is Cloudy/Rainy/Stormy
during this period, the “Moon phase & Star” icon may

13
not appear.
The “Rainy” and “Stormy” icons differ only in the drop-•
ping frequency of the rain. The rain dropping frequency
in the “Stormy” icon is faster than that in the “Rainy”
icon.
The “Snowy” weather forecast is not based on the atmo-•
sphere pressure, but based on the outdoor temperature.
When the outdoor temperature is below 26˚F(-3°C), the
“Snowy” weather indicator will display on the LCD.
RECEPTION OF RADIO CONTROLLED TIME SIGNAL
The time and date are radio controlled. The current time and
date are automatically synchronized with the time signal
transmitted from Germany (DCF 77) / UK (MSF) / USA
(WWVB) provided the device is within about a 932 mile
(1500 km) range of the transmitter. A small map icon will be
displayed when the Weather Station is activated in America,
denoting the current time zone. Germany is indicated with a
“D” icon, UK is indicated with an “M” icon.
