3.1 Important Information
●In order to get the full screen brightness and easy visibility of all numbers and symbols,
we recommend you use the included mains adaptor rather than batteries for the main
unit.
●The remote sensor will work better if the main unit is powered by the included mains
adaptor rather than batteries.
●Regarding the wireless remote sensor (which can be positioned indoors or outdoors),
if it is used outside particularly in cold conditions we recommend the use of Lithium AA
(requires 2) batteries as this will result in a more powerful signal and ensure no signal
loss. This is only precautionary advice and the remote sensor does work ne with normal
Alkaline batteries.
●The weather station needs to be powered for 12 hours before an accurate prediction will
display.
3.2 Initial Operation
●Either Connect the mains power or open the Weather Station Battery compartment
and insert 2 x AA batteries observing the correct polarity (+ and - marks) , then close the
battery compartment.
●When the power is connected all the icons on the LCD display will light up for 3 seconds,
you will hear a beep tone and the weather station will start to detect the indoor
temperature and humidity.
●The weather station will automatically search for the time via the MSF antenna within 7
minutes of powering on.
●Next the Weather Station will attempt to connect with the outdoor sensor. This lasts
approximately 3 minutes and is displayed by the RF icon ashing (A7).
●Remove the battery compartment on the Wireless Outdoor Sensor, insert 2 x
AAA batteries observing the correct polarity (+ and - marks) and close the battery
compartment.
●Once the weather station has created a connection to the outdoor sensor the clock you
will see the temperature displayed under the Outdoor Icon (A7).
●If Weather Station fails to receive a transmission from the outdoor sensor (“- -”
is displayed on the LCD), press and hold the ▼button for 3 seconds to receive
transmission manually.
●The RF icon will ash on the LCD and the outdoor temperature will show when it is
connected.
3.3 Backlight
●When using battery power the backlight will be o. Press the SNOOZE/LIGHT button to
enable the backlight for 15 seconds.
●When using Mains power the backlight will be lit continuously. To change the brightness
of the backlight switch the backlight switch to either HI or LO.

4. TIME AND CALENDAR SETTINGS
4.1 Automatic Time/Date Setting
●The Weather Station automatically starts the MSF Signal search after 7 minutes of any
restart or change of batteries.
●To manually start the MSF signal search, press and hold down the ▲button for 2
seconds.
●The radio mast icon will ash showing it is searching for signal.
●Once the signal is found the Time and Date will be automatically set. If no signal is
found within 7 minutes the radio mast icon will disappear and it will automatically start
searching again in 1 hour.
4.2 Automatic Time/Date Further Information
●During the MSF signal search mode, the SNOOZE/LIGHT button will only brighten the
screen from its dimmed mode whilst searching for the MSF signal and the ▲button will
cancel the MSF signal search. A ashing radio mast icon indicates that the MSF signal
search is in progress. To cancel the MSF signal search, press the ▲button once.
●A continuously displayed radio mast icon indicates that the MSF signal has been received
successfully.
●At 1:00 / 2:00 / 3:00am the Weather Station automatically carries out a synchronization
procedure with the MSF signal to correct any deviations to the exact time. If this
synchronization attempt is unsuccessful (The radio mast symbol disappears from the
display), the system will automatically attempt another synchronization at the next full
hour. This procedure is repeated automatically up to 5 times.
●If the clock cannot receive the MSF signal (because the distance is too great to receive a
signal from the transmitter in Anthorn, Cumbria), you have the option of setting the time
manually and instructions can be found on page 7. As soon as the reception of the MSF
signal is received the Weather Station is re-adjusted automatically.
●We recommend a minimum distance of 2.5 meters (8.2 Feet) to all sources of
interference, such as televisions or computer monitors.
●Radio reception can be weaker in rooms with concrete walls and in oces. In such
extreme circumstances, place the system close to the window for better signal reception.

7.7 Barometric Pressure History
The barometric pressure history for the previous 24 hours is shown on the graph under
the current pressure reading. It shows whether the reading was higher or lower than the
previous hours reading.
7.8 Relative Barometric Trend Display
After you insert the batteries, the weather station measures the current barometric
pressure. The trend display shows a neutral relative pressure course . The further
course of the trend display is determined as follows:
●If, after an hour, the relative barometric pressure is higher than the value measured rst,
then a positive course is displayed .
●If, after an hour, the relative barometric pressure lower than the value measured rst,
then a negative course is displayed .
●If the relative barometric pressure does not change within an hour, the the upward
or downward pointing arrow becomes a horizontal arrow. The measured relative
barometric pressure is then taken as the neutral value from which further prognoses are
made.
7.5 Temperature / Humidity Trend Display
After you insert the batteries, the weather station measures the current temperature and
humidity. The trend display shows a neutral temperature/humidity course . The
further course of the trend display is determined as follows:
●If, after an hour, the temperature/humidity is more than the value measured rst, then a
positive course is displayed .
●If, after an hour, the temperature/humidity is lower than the value measured rst, then a
negative course is displayed .
●If the temperature/humidity does not change within an hour, then the upward or
downward pointing arrow becomes a horizontal arrow. The measured temperature/
humidity is then taken as the neutral value from which further prognoses are made.

8. WEATHER FORECAST / MOON/TIDE PHASES
11
8.1 Weather Forecast
The weather station use the air pressure data to create a weather forecast for the next 8
hours.
The following weather symbols are used to represent the weather forecast:
8.3 The Moon and Tide Phases
The Weather Station has a display which will automatically display the current Moon / Tide
Phases based on the date. Below are the dierent moon phases shown on the display:
Note:
●The data shown within the rst 12 hours after inserting the batteries may not be correct, as the weather
station has to get used to the environmental circumstances after the restart.
●The weather station shows the forecast for the next 8 hours not the current weather.
●Please take the weather forecast from your local weather forecasting service into account as well as the
forecast from your weather station. If there are discrepancies between the information from your device
and from the local weather forecasting service, please take the advice of the latter as authoritative.
●The weather forecast is calculated from evaluation of uctuations in the barometric pressure and may
deviate from the actual weather conditions.
8.2 Comfort Display
Indoor comfort is calculated using the indoor temperature and humidty readings and a total
of 5 levels can be displayed, these are:
8.4 Charging Function
●When using the 5V power adapter, the USB plug on the back of the weather station can
be used for charging mobile phones etc.
