WIRELESS WEATHER STATION
C-8154
USER’S INSTRUCTIONS
P17815400030
p. 1
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 weather forecast, indoor temperature, pressure,
moon phase, time and date, as well as the temperature
measured and transmitted by the sensor. It is able to receive and display readings from up to 3 remote sensors.
The receiver unit retains the minimum and maximum
temperatures and relative humidity readings measured at
various locations. 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
a r e automatically synchronized with the time signal
transmitted from Frankfurt Germany (DCF77) / UK (MSF) /
US (WWVB). The signal can cover a distance of about 1500
km from the related transmitter.

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:
l Reorient or relocate the receiving antenna.
l Increase the separation between the equipment and receiver.
l Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
l Consult the dealer or an experienced radio/TV technician for
help.

WEATHER FORECAST
The built-in barometer can notice atmospheric pressure
changes. Based on the data collected, it can predict the
weather condition in the forthcoming 12-24 hours. The
effective covers area ranges from 30 to 50 km.
NOTE:
1. The accuracy of a general pressure-based weather
forecast is about 70 to 75% , and therefore, cannot be
held responsible for any inconvenience caused by an
inaccurate data.

NOTE:
1. Do not set the weather indicator when it is raining.
Raining will give unstable data.
2. Do not set the weather indicator in night time.
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 Frankfurt, Germany (DCF77), UK/
(MSF) / US (WWVB) provided the device is within about of
1500 km range of the transmitter.
When used for the first time (after inserting the batteries or
pressing RESET), the clock starts receiving time signals
and the reception display flashes.
SIGNAL STRENGTH INDICATOR
HOW TO READ INDOOR AND OUTDOOR
TEMPERATURE RECORDS
Change the temperature unit by sliding ºC / ºF slide switch
to ºC for Centigrade or ºF for Fahrenheit.
If the readings go above or below the specified range, the
receiver and transmitter will keep show the last record within
the operation range.
NOTE:
1. If no signals are received or the transmission is
interfered with, “---” appears in the display.
2. Locate the clock in other position and make sure the
transmission is within the effective range of 30 meters
approx.
3. After several trials but in vain, please reset the clock
thoroughly. Try out where your multifunctional alarm
clock receives the signals best.
The signal indicator displays signal strength in 3 levels.
Wave segment flashing means time signals are being
received. The signal quality could be classified into
