Congratulations on your purchase of this weather station, MeteoClock SM1120. Please take the time
to read and understand this manual so you can begin to enjoy the convenience and features this 
product has to offer.

What exactly is a Weather Station?

Lexibook digital stations measure not only the time in progress - thanks to their built-in clock - but
also the actual weather!

The MeteoClock SM1120 incorporates different functions:

- Thermometer: 

Temperature is displayed in real time to the nearest tenth of a degree Celsius. Thanks to its 
wireless sensor, the station can sense from a distance the outside temperature or that of another
room!

- Hygrometer: 

Outdoor  hygrometry is expressed in percentage of humidity in the ambient air. The ideal “Comfort”
Zone for the human body ranges from 35 to 65% hygrometry for a given temperature in between
18 and 24ºC.

TROUBLESHOOTING

Solution:

Re-synchronize receiver by holding 

ALARM/PM/AM/°C/°F 

for 3 seconds until a 

beep is heard. 

Ensure  the  remote  transmitter  is  out  of  direct 
sunlight, and away from sources of heat.

Repeat the learning procedures.
-  Temperature may be below -30°C.
-  Batteries  in  remote  transmitter  may  need

changing.  

-  Move remote transmitter closer to the receiver.
-  Make  sure  remote  transmitter  is  away  from

sources of electrical disturbance.

Problem:

The  temperature  measurement  of
remote transmitter and receiver does
not match. 

Temperature  reading  of  the  outdoor
remote transmitter seems too high. 

Receiver  is  no  longer  receiving
remote transmitter signals or tempe-
rature display reads Lo.
