WIRELESS WEATHER STATION
Model 81690
USER'S INSTRUCTIONS
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, relative humidity, pressure, moon phase, time and date, as well as the
temperature and relative humidity 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 are automatically synchronized with the
time signal transmitted from the atomic clock in FT. Collins, Colorado. The signal can cover a
distance of about 2,000 miles.
