BRIEFINTRODUCTION
Thank you for your purchase of thisWeather Station
with Radio-Controlled Alarm Clock and Ice Alert.
Please read these instructions carefully and keep
the manual well for future reference.
The receiver unit has a clear and easy-to-read
display that shows the indoor temperature, time,
the maximum & minimum temperature records in
the past 24 hours as well as the outdoor temperature
measured and transmitted from the remote sensors.
It is able to receive and display readings from up to
3 remote sensors.
The 433 MHz technology means no wire installation is
required and you can place the sensors anywhere you
like within 30m (100ft) from the main (indoor) unit.
This product is designed to synchronize its date and
time automatically once it is within range of the
signal from the atomic clock in Germany/England.

3. Press “RESET” key to restart the clock.
4. Replace the battery door.
Note
The transmission range may vary depending on
many factors. You may need to experiment with
various locations to get the best results.
Standard Alkaline batteries contain significant
amounts of water. Because of this they will freeze
in low temperatures of approximately -12°C (10°F).
Disposable Lithium batteries have a much lower
threshold for temperature with an estimated
freezing range of below -30°C (-22°F).
Wireless ranges can be impacted by a variety of
factors such as extremely cold temperatures.
Extreme cold may temporarily reduce the effective
range between the sensor and the base station. If
the unit’s performance fails due to low temperature,
the unit will resume proper functioning as the
temperature rises to within the normal temperature
range (i.e. no permanent damage will occur to the
unit due to low temperatures).

RECEPTIONOFRADIOCONTROLLEDTIME
SIGNAL
The time and calendar are radio-controlled. The
current time and calendar are automatically
synchronized with time signal transmitted from
Germany/England.
When used for the first time (after inserting batteries or
pressing “RESET” key), and then after 5 minutes, the
clock will start to receive the time signal. The signal
reception indicator will be flashing for 7 minutes.
SIGNAL RECEPTION INDICATOR
The wave segment flashing means time signals are
being received. The signal quality could be classified
into 3 types:
Note
1. The unit will automatically search for the time
signal at 2:00 (3:00 or 4:00 is also available if
the signal is not received at 2:00), 8:00, 14:00
and 20:00 each day.
2. Always place the unit away from interfering
sources such as TV set, computer, etc.
3. Avoid placing the unit on or next to metal
plates.
4. Closed area such as airport, basement, tower
block or factory is not recommended.
5. Do not start reception in moving articles such
as vehicles or trains.
TIME AND CALENDAR MANUAL SETTING
If you are out of reach of the Radio Controlled
sensor or if the reception is not reachable, the time
and calendar can be set manually. As soon as the
signal of sensor is received again, the clock will
automatically synchronize with the exact time and
calendar.
1. In normal time mode, press “SET CLOCK”
key once to enter the time setting mode.
2. Press “+/CHANNEL” or “-/MIN.MAX.” key to
change the settings.
