After inserting the batteries, all the segments on the LCD will light up briefly
before displaying the time and all the other modes
Note: Please check that the frequency signals for both time and
temperature are received on the LCD. Should either signal not be
received, then see Checking for DCF-77 reception & Checking for
433 MHz reception below.
Time by radio controlled and manual setting:
The time is displayed on the top of the LCD. The time base for radio controlled
time is a Cesium Atomic Clock operated by the Physikalisch Technische
Bundesanstalt Braunschweig, which has a time deviation of less than one

Weather tendency icons
There are 3 weather icons on the second line of LCD which can be displayed
in any one of the following combinations:
Sunny Cloudy with
sunny intervals
For every sudden or significant change in the air pressure, the weather icons
will update accordingly to represent the change in weather. If the icons do not
change, then it means either the air pressure has not changed or the change
has been too slow for the Weather Station to register. However, if the icons
displayed is a sun or raining cloud, there will be no change of icon if the
weather gets any better (with sunny icon) or worse (with rainy icon) since the
icons are already at their extremes.
The icons displayed forecasts the weather in terms of getting better or worse
and not necessarily sunny or rainy as each icon indicates. For example, if the
current weather is cloudy and the rainy icon is displayed, it does not mean
that the product is faulty because it is not raining, it simply means that the air
pressure has dropped and the weather is expected to get worse but not
necessarily rain.
Note: After setting up, readings for weather forecasts should be discarded
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 an more
accurate forecast.
Common to weather forecasting, absolute accuracy cannot be
guaranteed. 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 for use in. In areas that experience sudden
changes in weather (for example from sunny to rain), the Weather

second in every one million years. This signal is coded and transmitted from
Mainflingen near Frankfurt via frequency DCF-77 and has a transmitting range
of approximately 1,500 km. The Weather Station receives this signal and
converts it to show the precise time and so when within this range the time
received is completely accurate.
Indoor temperature reading:
The indoor temperature is displayed underneath the time and will automatically
appear after few seconds when the batteries are inserted.
Minimum and maximum indoor temperature recordings:
Underneath the current indoor temperature reading are the minimum and
maximum indoor temperature recordings. These are simultaneously displayed
for constant and easy reading. This feature is useful for displaying the recorded
temperatures of the room which the Weather Station has been placed. When
a new temperature low or high is reached, it will be automatically updated and
displayed.

reading in degrees Celsius Relative humidity reading with comfort level reading (face icons)
The relative humidity with comfort level reading is displayed underneath the
indoor temperature. With this feature, users can determine how comfortable
the relative humidity is within their current surroundings. Again, as with the
indoor temperature, the relative humidity reading will automatically be taken
once the batteries are inserted.
Working together with relative humidity, the Weather Station will register a
comfort level reading by representation of a "
face. The temperature range between +20°C to +26°C and relative humidity
range between 45% to 65% will register the "Smiling" face. The "Sad" face
will appear should either the temperature or humidity readings be outside
these set ranges. This means, the "Smiling" face represents a comfortable
level and the "Sad" face represents an uncomfortable one.

that the relative humidity reading is outside its comfort level range. However,
"DRY" or "WET" will not appear if only the temperature reading is outside its
comfort level range. The "
humidity level is below 45% or "WET" will appear if the level is above 65%.
The weather tendency indicator
The weather tendency arrows is located on the above and below the weather
Rainy icons and indicates the change in air-pressure and thus, forecasts the expected
weather.
The tendency arrows can be displayed as follows:-

" "Sad" face appears with the word "DRY" or "WET", it means
" "Sad" face and "Dry" will appear if the relative
Station will be more accurate compared to use in areas where the
weather is stagnant most of the time (for example mostly sunny).
If the Weather Station is moved to another location significantly higher
or lower than its initial standing point (for example from the ground
floor to the first floor of a house), remove the batteries and re-insert
them after about 30 seconds. By doing this, the Weather Station will
not mistake the new location as being a possible change in air-pressure
when really it is due to the slight change of altitude. Again, discard
weather forecasts for the next 12 to 24 hours as this will allow time for
operation at a constant altitude.
Tendency arrow pointing upwards:
this means that the air-pressure is
increasing and so the weather is
expected to improve.
Tendency arrow pointing downwards:
this means that the air-pressure is
decreasing and the weather is
expected to become worse.
