contact breaker.
• Then close the battery compartment cover.
4.2 Replacing the batteries
Note – Replacing the batteries
• Note that the stations have to be resynchronised each
time after you change the batteries in the measuring or
base station.
• To do this, remove the batteries from the other station and
then reinsert them, or change them as required.
Measuring station
• If the symbol (next to the outdoor temperature (13)) is
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.
Base station
• If the symbol (next to the indoor temperature (17)) is
displayed, replace the two AA batteries in the base device
with new ones.
• Open the battery compartment (26), 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
• We recommend initially placing the base and measuring
stations in the intended locations without installing them
and making all the settings described in
6. Operation
– to do.
• Only install the stations once the appropriate settings
have been made and a stable wireless connection is
established.
Note
• The wireless transmission range between the measuring
station and base station is up to 30 m in open spaces.
• Before installation, ensure that 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).
• Before the final installation, ensure that there is sufficient
reception between the intended installation locations.
• When installing the measuring station, ensure that it is
protected from direct sunlight and rain.
• The international standard height for measuring air
temperature is 1.25 m (4 ft) above ground.
Warning
• Buy special or suitable installation material from a
specialised dealer for wall-mounting.
• Ensure that no faulty or damaged parts are installed.
• Never apply force during installation. This could damage
the product.
• Before installation, 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.
5.1 Base station
• Use the base (27) to position the base station on a level
surface.
• Alternatively, you can install the base station on a wall using
the opening (20) on the back.
5.2 Measuring station
• You can also position the measuring station on a level
outdoor surface.
• We recommend 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 a connection to the measuring
station and to the radio signal.
Note
• The first search for the measuring station can take up to
3 minutes; the search for the radio signal can take up
to 7 minutes.
• If the base station receives no signal from the measuring
station, it automatically begins to search for the radio
signal after 3 minutes.
• The respective symbols will flash during the connection
attempts:
connection to the measuring station,
connection to the DCF signal
• Do not press any buttons during setup. Otherwise, values
may not be transmitted correctly and there is a risk of
value errors and inaccuracies.
• Do not 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 first 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
flashes.
