5. Outdoor transmitter
• The sensor will automatically transmit temperature to the display unit on channel 1 after batteries
are inserted.
• After successful installation close the battery compartment of transmitter carefully.
• Please reset the instrument and follow the battery installation procedure if the instrument does
not work properly. Change the batteries.
5.1 Additional transmitters
• For having more than one external transmitter (cat. no 30.3126), select a different channel (2 or 3)
for each transmitter by the CHANNEL switch inside the battery compartment of the transmitter.
• Open the battery compartment and insert 2 batteries 1.5 V AAA, polarity as illustrated.
• Press and hold the ▼ button on the display unit for 3 sec. to start initialization manually.
• If you have installed more than one transmitter, press channel button to change between the out-
door transmitters.
• You can also choose an alternating channel display. Press and hold channel button until the circle
symbol appears for alternating channel.
• To deactivate the function press and hold the CHANNEL button and the symbol disappears.
5.2 Positioning of display unit and transmitter
• Choose a shady and dry position for the transmitter. (Direct sunshine falsifies the measurement and
continuous humidity strains the electronic components needlessly).
• Place the weather station in the living room with the table stand (fold our) or the silver coloured
additional stand. With the hanging device you can fix it on a wall. Avoid the vicinity of any interfer-
ing field like computer monitors or TV sets and solid metal objects.
• Check the transmission of 433 MHz signal from the transmitter to the display unit (transmission
range 40 m free field). Within ferro-concrete rooms (basements, superstructures), the received sig-
nal is naturally weakened.
• If necessary choose another position for transmitter and/or display unit.
• Is the transmission successfully, you can wall mount the transmitter. Screw the holder onto a wall.
The transmitter simply clicks into the holder. When inserting or removing the transmitter from the
wall holder please hold both units securely.
• The transmitter can also be positioned on a flat surface by securing the bracket to the bottom of
the transmitter.
6. Battery replacement
• When the batteries of the weather station or the transmitters are used up, the low battery symbol
appears beside the time display (weather station) or beside the temperature display of the appro-
priate outdoor transmitter.
• Remove the holder of the transmitter and slide the battery cover downwards. Insert 2 new batter-
ies 1.5 V AAA in the battery compartment of the transmitter, polarity as illustrated. Place the bat-
tery cover on the housing and slide it upwards.
• Open the battery compartment of the weather station by pushing the battery cover downwards
with your thumbs. Remove the batteries by pressing a pointed object into the small opening. Insert
2 new CR2032 button cell batteries in the battery compartment of the station, observing the
correct polarity (+ pole above). Place the battery cover on the housing and slide it upwards.
• When changing the batteries in the transmitter, press ▼ button on the station for three seconds to
relearn the transmitter.
