• Open the battery compartment cover (L) on the top of the pole mount
(H) on the outdoor sensor. To do this, release the single screw on the
battery compartment cover and unscrew the screw with a suitable
screwdriver.
• Insert three AA/Mignon batteries (not included) using the correct
polarity into the battery compartment (observe plus/+ and minus/-).
• After inserting the batteries, the LED indicator (J) starts to ash. New
weather data are transmitted after 12 seconds in each case.
• If the LED indicator (J) does not light up, check that the batteries are
functional and have been inserted correctly.
• Close the battery compartment again. Ensure that the sealing
ring is in the correct position. This is necessary to seal the battery
compartment watertight, otherwise moisture could penetrate the
sensor.
• Screw the screw on the battery compartment back in rmly.
The weather station and/or the outdoor sensor can be operated by rechargeable battery. However, the
operating time and the display contrast are greatly reduced due to the lower voltage (battery = 1.5 V,
rechargeable battery = 1.2 V). In addition, rechargeable batteries are very sensitive to temperature, which
can result in further reduction of the operating time when used in the outdoor sensor. We therefore recom-
mend the use of high-quality alkaline batteries and not rechargeable batteries, both for the weather station
as well as for the outdoor sensor.
When using the outdoor sensor in colder climates, lithium batteries should be used as they are less sensi-
tive to cold temperatures. Alkaline batteries are sufcient under other climatic conditions.
2Inserting the batteries into the weather station
• Open the battery compartment cover (9) on the base of the weather station.
• Insert three AAA batteries (not included) with correct polarity into the battery compartment (observe plus/+ and
minus/-).
Use of the backup batteries ensures that data can be backed up even if there is no power supply from the
power adapter. The batteries in the weather station are used to supply power to various functions when
the power adapter is not connected. The time and date, the maximum and minimum temperature values
as well as the weather recordings from the outdoor sensor over the past 24 hours are stored in the internal
memory. The alarm settings and the channel information of the outdoor sensor are also maintained by the
battery power supply. Bear in mind, however, that the battery is consumed very quickly when used exclu-
sively in battery operation (approx. 1 week).
• After inserting the batteries, all display elements are briey displayed on the LC display.
• Replace the battery compartment lid.
• The weather station starts searching for the time signal (DCF) after approx. 8 seconds.
It is possible that atmospheric interference may prevent the DCF signal from being received. If nothing
appears on the LC display (8), press the RESET button (19) using a pointed object to reset the weather
station. All display elements appear briey on the LC display (8). Two short beeps can be heard.
• When the DCF signal has been received, the symbol is displayed in the corresponding area of the LC display.
