WEATHER FORECAST INDICATOR
The built-in barometer can notice atmosphere pressure
changes. Based on the data collected, it can predict
the weather conditions in the forthcoming 12-24 hours.
Note:
1.
The accuracy of a general pressure-based
weather forecast is about 70% to 75%.
2.
The weather forecast is meant for next 12 to 24
hours. It may not necessarily reflect the current
situation.
3.
The “Rainy” and “Stormy” icons are different
only in the dropping frequency of the rain. The
rain dropping frequency in “Stormy” icon is faster
than that in “Rainy” icon.
4.
The “Snowy” weather forecast is not based on
the atmosphere pressure but on the outdoor
temperature. When the outdoor temperature is
below -3°C (26°F), the “Snowy” icon will be
displayed on the LCD.
ABOUT THE MOON PHASE
The unit has 8 different moon phases. It will change
according to the lunar calendar.
BATTERY REPLACEMENT
If the LCD becomes dim, it means that you should
replace batteries of the clock immediately.
If the low battery indicator “
” appears in the
WEATHER FORECAST AND TEMPERATURE
window
of the clock (“

should replace batteries of transmitter at once.
