displayed, replace the two AA batteries of the measuring
station with two new ones.
•Open the battery compartment (30), remove and properly
dispose of the dead batteries and insert
•two new AA batteries with the correct polarity.Then close
the battery compartment cover.

5. Installation
Note –Installation
•Werecommend initially placing the base and measuring
stations in the intended locations without installing them
and making all the settings described in
6. Operation –todo.
•Only install the stations once the appropriate settings
have been made and astable wireless connection is
established.
Note
•The wireless transmission range between the measuring
station and base station is up to 30 minopen spaces.
•Beforeinstallation, ensurethat wireless transmission
will not be disrupted by interference or obstacles like
buildings, trees, vehicles, high-voltage lines, etc. To
avoid transmission interference, do not operate adjacent
wireless devices on the same frequency
(433 MHz).
•Beforethe nal installation, ensurethat thereissucient
reception between the intended installation locations.
•When installing the measuring station, ensurethat it is
protected from direct sunlight and rain.
•The international standardheight for measuring air
temperatureis1.25 m(4ft) above ground.
Warning
•Buy special or suitable installation material from a
specialised dealer for wall-mounting.
•Ensurethat no faulty or damaged parts areinstalled.
•Never apply force during installation. This could damage
the product.
•Beforeinstallation, ensurethat the chosen wall is suitable
for the weight to be mounted, and make surethat there
arenoelectrical wires, water,gas or other lines at the
installation site on the wall.
5.1 Base station
•Use the base (27) to position the base station on alevel
surface.
•Alternatively,you can install the base station on awall using
the opening (20) on the back.
5.2 Measuring station
•You can also position the measuring station on alevel
outdoor surface.
•Werecommend installing the measuring station securely on
an outdoor wall using the recess (29).
•Install an anchor,screw,nail, etc. in the wall of your choice.
•Hang up the base/measuring station using the opening (29)
intended for this purpose.
6. Operation
6.1 Connection to the measuring station
•When the batteries have been inserted, the base station
automatically searches for aconnection to the measuring
station and to the radio signal.
Note
•The rst search for the measuring station can take up to
3minutes; the search for the radio signal can take up
to 7minutes.
•Ifthe base station receives no signal from the measuring
station, it automatically begins to search for the radio
signal after 3minutes.
•The respective symbols will ash during the connection
attempts: connection to the measuring station,
connection to the DCF signal
•Donot press any buttons during setup. Otherwise, values
may not be transmitted correctly and thereisarisk of
value errors and inaccuracies.
•Donot change the location of the base station during the
search processes.
•The process is completed when the indoor (17) and
outdoor (13) measurement data is displayed.
6.2 Basic and manual settings
Automatic setting using the DCF signal
When the base station has been switched on for the rst time
and successful transmission has been established between
the base station and the measuring station, the clock will
automatically search for the DCF signal. During the search, the
radio symbol ashes.
