TEMPERATURE & HUMIDITY TREND
The trend indicator shows the trend of temperature & humidity determined by the
particular sensor in the past half hour interval.
Animated weather forecast symbols
This weather station is capable of detecting barometric pressure changes, and based on the
data collected, can predict the weather
for the next 12 to 24 hours. The effective range covers an area of 30 – 50km.
You can set high temperature or low temperature alarms for one local channel and for one remote
channel.
Local temperature alarm
1.Scroll to temperature alarm mode by using MODE (Inside).
2.The default value 14°C or existing preset will flash.
3.Press Hour/+ or Minute/– keys to set the temperature limit value.
4.Press Snooze key continuously to scroll and select the high temperature alarm , low
temperature alarm or disable the alarm function (blank).
5.Press mode to save your settings.
Outdoor temperature alarm
1.Scroll to remote channel temperature alarm mode by using mode.
2.Press CHN to select the channel of the desired transmitter.
3.The default value 14°C or existing preset will flash.
4.Press Hour/+ or Minute/– keys to set the temperature limit value.
5.Press Snooze key continuously to scroll and select the high temperature alarm , low
temperature alarm or disable the alarm function (blank).
6. Press mode to save your settings.
When the temperature alarm sounds
The icon signals that the temperature has exceeded the preset temperature limit.
a.Press any key to stop temperature alarm.
b.If no key is pressed, the temperature alarm will automatically stop itself after one minute.

WEATHER FORECAST & DISPLAY
Storm Alert
The storm symbol will flash to warn of a thunderstorm.
It is activated when pressure falls/rises and temperature plunges.
About Snow and Freeze Warning
The snow symbol will flash to warn that it might snow.
Activated when the temperature of Channel 1 is between -1.9 °C & +2.9 °C.
The snow symbol will appear solid when the temperature of channel 1 falls below - 1.9 °C, and it
is freezing.
Note:
The remote sensor set at channel 1 displays the weather forecast icons (as well as the trend
indication). Please place it outdoors.
REMARKS:
After having completed the settings of your weather station, please discard the readings of the
weather forecast for the next 12-24 hours. This will allow sufficient time for the Weather Station
to operate at a constant altitude and therefore result in a more accurate forecast. Absolute
accuracy cannot be guaranteed regarding weather forecasting. The weather forecasting feature
is estimated to have an accuracy level of about 75% due to the varying areas the Weather
Station has been designed to be used in. If the Weather Station is moved to another location
significantly higher or lower than its initial standing point (e.g. from ground floor to 1st floor of a
house), remove the batteries and reinsert them after about 30 seconds. By doing this, the
Weather Station will mistakenly consider the new location as a possible change in air pressure.
Again, discard the weather forecasts for the next 12-24 hours as to allow time for operation at a
constant altitude.

Throughout the 28 days of the lunar month, the aspect of the moon changes. Indeed, the
moon, being spherical, is always half lightened up by the sun. As the moon rotates
around the Earth, the appearance of its lightened side changes continuously. This
phenomenon creates moon phases. The moon phase on your MeteoClock is automati-
cally updated according to the year/ month/day.
