RADIO CONTROLLED WIRELESS WEATHER STATION
MODEL C8243
USER’S INSTRUCTIONS
and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause
harmful interference to radio communications.
However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference
by one or more of the following measures:
•
•
•
•
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and
receiver.
Connect the equipment into an outlet on a circuit
different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV
technician for help.
The multifunctional weather station is equipped with many
functions providing thorough weather information to you.
The receiver unit has a clear, easy-to-read display that
shows the weather forecast, minimum/maximum indoor and
outdoor temperature,moon phase, as well as the time and
date. It is able to receive and display readings from the
remote sensors.
The 433 MHz technology means no wire installation is
required and you can place the sensors anywhere you like.
With radio controlled function, the current time and date are
automatically synchronized with the time signal transmitted
from Germany (DCF77) / UK (MSF) / USA (WWVB) (It depends
on which version you purchase). The signal can cover a
distance of about 1500 km from the related transmitter.

appliances to minimize the interference. Position the
receiver and transmitter within the effective
transmission range: 30 meters in usual circumstances.
ABOUT THE WEATHER INDICATOR
Waxing gibbous
Waning crescent
The built-in barometer can notice atmospheric pressure
changes. Based on the data collected, it can predict the
weather conditions in the forthcoming 12-24 hours.

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 reflect the current situation.
The “Sunny” icon can only appear from 6 AM to 8 PM;
while 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; while if the weather is Cloudy/Rainy/Stormy
during this period, it may not appear either.
The “Rainy” and “Stormy” icons are different only in the
dropping 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
atmosphere pressure, but based on the outdoor
temperature. When the outdoor temperature is below
-3°C, the “Snowy” weather indicator will display on the LCD.

Slightly cloudy
VIEWING THE CHANNEL
The default channel is Channel 1. In normal time mode,
press the “UP” key to view the channel from 1 to 3.
HOW TO READ INDOOR AND OUTDOOR TEMPERATURE
RECORDS
