COMMISSIONING
Battery installation
Note: observe the correct battery polarity to prevent damage to the weather station. Use quality
alkaline batteries for the main unit; we recommend using lithium batteries for the wireless
sensor due to their resistance to frost. Do not use rechargeable batteries. Do not expose
the batteries to high temperatures like fire or direct sunlight
Main unit
The main unit can be powered by batteries (short-time display backlight for 15 seconds will be possible) or
by an AC adaptor (permanent display backlight will be possible). If the main unit is powered by an adaptor,
the batteries are not being used, therefore you should remove them to avoid damage to the batteries and to
the main unit. Use only the delivered AC adaptor.

Placement of the weather station
Main unit
Select the location of the main unit away from direct sunlight. Test the connection to the wireless sensor
before final installation. If there is a problem with the signal reception, select another location. There is a
mounting hole for suspension on the rear of the main unit. You may also put the main unit on a flat surface
using the folding support. Placement near TVs, monitors, computers, etc. may negatively affect the
reception of the DCF-77 signal and the wireless sensor signal.
Wireless sensor
Place the wireless sensor away from direct sunlight not to compromise the measurement. Placement
outdoors, at the northern wall is recommended. Obstacles such as walls, concrete, metal structures and
large objects reduce the signal range. Position the wireless sensor vertically for optimum signal
transmission. Maximum open space signal range is 60 meters.
The signal range may be affected by obstacles (walls, trees) and other electrical devices (TVs, monitors,
etc.).
Time controlled by the DCF-77 radio signal
The weather station is equipped with the DCF-77 time/date control signal receiver, the signal is
broadcasted by a transmitter from Frankfurt am Main, Germany, with a range of about 1500 km. When
outside this range, the time and date can be adjusted manually. The time and date are adjusted every day.
When the batteries are inserted or the AC adaptor is plugged to the main unit, the display lights up, all
display segments are briefly displayed, and a beep sounds and the wireless sensor signal reception
commences.
After the connection with the wireless sensor has been established, the reception of the DCF-77 is
commenced, indicated by flashing icon . This process may take several minutes. The display will be off
during the reception of the DCF-77 signal and the functionality of the main unit will be limited. Only buttons
and will function. When the signal is received successfully, the display shows the current time,
date and signal reception icon. The icon shows the signal reception strength, the more bars the better
the signal. The weather station will automatically receive the DCF-77 signal for time adjustment every day
at 1:00, 2:00 and 3:00. If reception is unsuccessful, reception will be attempted again in another hour, five

6
times in total. The received time is compared with the time on the main unit and adjusted if necessary. For
better signal reception, place the main unit near a window.
If the DCF-77 signal is not received (icon is not displayed), reception will be interrupted, and it will be re-
attempted in an hour until the DCF-77 signal is received successfully.
Note:
The received DCF-77 time adjustment signal strength may be affected by the geographical location or the
premises where the weather station is located.
For better reception, the main unit should be placed on a flat non-metallic surface, near a window on the
upper floor of your house away from electrical appliances such as a TV, computer, etc.
