• Ensure that no faulty or damaged parts are installed.
• Never apply force during mounting. This could damage the product.
• Before mounting, ensure that the chosen wall is suitable for the weight to be mounted, and make sure that there are no electrical wires, water, gas or other lines at the  installation site on the wall.
• Do not mount the product above locations where persons might linger.

5.1 Base station

• Use the base (35) to position the base station on a level surface.
• Alternatively, you can install the basestation on a wall using the opening (33) on the back.

5.2 Measuring station

• You can also position the measuring station on a level outdoor surface using the base.
• We recommend installing the measuring station securely on an outdoor wall.
• Install an anchor, screw, nail, etc. in the wall of your choice.
• Hang up the base/measuring station using the opening (33/39) intended for this purpose.

Operating the Base Station

Note – Input
Hold down the MIN/MAX button (30) or the + button (31) to select the values faster.
If you press the SNOOZE / LIGHT button (32), the display will light up for approx. 10 seconds.

6.1. Automatic initial setup
All available LCD segments on the display are displayed briefly after turning the measuring station on for the first time.

• The base station then performs automatic initial setup.
  During setup, the base station performs measuring station synchronisation, the pressure measurement values are stabilised and factory settings are set.

Note – Initial setup

• Initial setup takes approx. 3 minutes.
• Do not press any buttons during setup. Otherwise, values may not be transmitted correctly and there is a risk of value errors and inaccuracies.
• The setup process is completed when the indoor (12, 14) and outdoor (18, 20) measurement data is displayed
• After the first time the base station is switched on and successful transmission is established between the base station and the measuring station, the clock will automatically search for a DCF signal. During the search, the wireless symbol (27) will flash.

Note – Time settings

• If, during the first minute of the initial setup, no DCF signal can be found, the search is stopped and repeated every two hours. The wireless symbol will go out.
• You can, however, set the time and the date manually.
• The clock automatically continues to search for the DCF signal on a daily basis. If the signal is received successfully, the manually-set time and date are overwritten.

Note – Summer time
The clock automatically switches to summer time.
appears on the display as long as summer time is activated.

6.2. Basic and manual settings

• Press and hold the SET button (28) for approx. 3 seconds to make the following settings one after the other:
• Time zone (24)
• 12/24 hour format (24)
• Hours (24)
• Minutes (24)
• Year (21)
• Month (21)
• Day (21)
• Temperature unit (°C / °F) (13+17)
• Room temperature value (12)
• Room humidity value (14)
• Outdoor temperature value (18)
• Outdoor humidity value (20)
• Atmospheric pressure unit (hPa / inHg) (5+9)
• Relative atmospheric pressure reference value (5)
• Atmospheric pressure threshold value (5)
• Storm threshold value (5)
• To select the individual values, press the MIN/MAX button (30) or the + button (31) and confirm each selection by pressing the SET button (28).
• Press the SET button (28) to adopt the set value displayed and to skip.
• If you do not make an entry for 20 seconds, you automatically exit setup mode. Alternatively, press the SNOOZE / LIGHT button (32) to exit setup mode before  selecting all the values.

Note – Time zone

• The DCF signal can be received over a wide range, but always corresponds to the applicable Central European Time in Germany. Make sure you account for the time  difference in countries with another time zone.
• If you are in Moscow, the time is 3 hours later than in Germany. This means that you should set +3 for the time zone. The clock then automatically sets itself 3 hours  ahead after receiving the DCF signal or according to the manually set time.

Note – Temperature and humidity

• In terms of accuracy, the temperature and air humidity measurement is intended for private, non-commercial use.
• In individual cases, the measured values displayed may differ slightly from comparison values, e.g. values from a calibrated measuring device. Using the Basic and manual  settings, you can adjust and recalibrate the values for the room/outdoor temperature and/or the humidity.
• We recommend that you do not manually calibrate the measured values, press the SET button (28) during manual setup to skip this step.

Note – Atmospheric pressure

• The absolute atmospheric pressure (abs) is a value measured at the installation location that cannot be changed.
• The relative atmospheric pressure (rel) is the absolute atmospheric pressure at the installation location corrected to the atmospheric pressure at sea level (msl).
• The reference value for relative atmospheric pressure is set to 1013.2 hPa as standard. For an exact measurement, adapt the reference value to your location. You can  manually set the reference value to within a range of 919.0 hPa and 1080.0 hPa.
• Information on the current relative atmospheric pressure for you location is available on the Internet, from your local meteorological office, on the radio, etc.

Note – Atmospheric pressure threshold value

• The weather forecast is based on atmospheric pressure changes, and you individually set their threshold values between 2 hPa and 4 hPa. The threshold value is set to 3  hPA as standard.
• A decrease or increase in the atmospheric pressure by at least the set threshold value is registered as a change in the weather.
•  For locations with frequent changes in atmospheric pressure,we recommend you set a higher atmospheric threshold value than for locations with a relatively constant  atmospheric pressure.

Note – Storm threshold value

• The storm forecast is also based on atmospheric pressure changes, and you individually set their threshold values between 3 hPa and 9 hPa. The threshold value is set to 6 hPA as standard.

• The storm warning display is activated if, over a period of three hours, there is a decrease or increase in the atmospheric pressure by at least the set threshold value.

• When the storm warning display is activated, the rain symbol and the trend arrow flash for three hours.

The weather forecast and the current weather are indicated by four different symbols (1):

• Based on the measured barometer values, the atmospheric pressure trend for the next few hours is displayed between the weather forecast symbols.

• The weather symbols change depending on the current relative atmospheric pressure and atmospheric pressure changes within the past six hours. If the weather is  changing, the atmospheric pressure trend arrows (3) flash for three hours to indicate the change in weather. The arrows (3) stop flashing when the weather conditions  have subsequently stabilised and the station has not detected any further changes in weather. Examples:

Decreasing / Weather is getting worse
Current weather: Cloudy
| Current weather: Slightly cloudy
Atmospheric pressure trend:
Increasing / Weather is improving
Weather forecast: Sun

• The bar graph (8) shows the history of the relative atmospheric pressure within the last 24 hours.

6.4. Temperature / atmospheric pressure display mode

• Press the SET button (28) repeatedly to change between the following displays:

• Outdoor temperature (18: TEMP)/ Dew point temperature (18: DEWPOINT)

• Absolute atmospheric pressure (7: abs)/Relative atmospheric pressure (7: rel)
  The applicable display begins to flash.

• While the display is flashing, press the MIN/MAX button (30) or the + button (31) to switch between the outdoor temperature and the dew point or between the  absolute and relative atmospheric pressure.

• Confirm your display selection by pressing the SET button (28).
  The weather station offers you the option to adjust the relative air pressure display according to the height of the location above sea level.
  To set / calibrate the relative air pressure, proceed as follows:

• Press and hold the SET button (28) until the time at the bottom edge of the display disappears.

• Now press the SET button (28) several times until “rel” appears next to air pressure and the numeric value for the air pressure flashes.

• Now use MIN/MAX (30) or + (31) to adjust the (current) relative value in 0.1 increments. Use the value from a calibrated weather station nearby or the value from a  weather service to set the value for the relative air pressure.
