6.1 Insert the batteries

• Remove the protective film from the display of the base station and the transmitters.
• Place the instruments on a table at a distance of about 1.5 meters from each other. Avoid being close to possi-
ble sources of interference such as electronic devices and radio equipment.
1. Open the battery compartment of the first transmitter.
2. Set the first transmitter to channel 1 by sliding the 1/2/3 slide switch to 1.
3. Insert two new AAA 1.5 V batteries, polarity as illustrated. All LCD segments will be displayed for a short
moment.
4. Subsequently, the measured temperature, humidity and channel number 1 appear.
5. Close the battery compartment.
• Repeat steps 1-5 for the other two transmitters. Select different channels for each transmitter with the 1/2/3
slide switch.
• Open the battery compartment of the base station and insert two new AA 1.5V batteries, polarity as illustrated.
• All segments will be displayed short and the backlight will turn on for a short moment.
• Close the battery compartment.
6.2 Transmitters reception
• After the batteries are inserted, the base station will automatically receive the measured values for 5 minutes.
The reception symbols flash on the display.
• If the reception of the measured values fails, dashes appear on the display. Check the batteries and try it again.
Check if there is any source of interference.
• If the reception is successful, the temperature, humidity and the reception symbol appear steadily on the base
station display next to the corresponding channel number.

10. Battery replacement
• As soon as the battery symbol appears on the base station in the display line of a channel or in the transmitter
display, change the batteries of the respective transmitter.
• As soon as the battery symbol appears in the display area for internal values, change the batteries of the base
station.
• Please note: When the batteries are changed, the contact between the transmitters and the base station must
be restored – so always insert new batteries into all devices or start a manual search for the corresponding
transmitter.
11. Location and mounting
• Place the transmitters at your chosen location. Should you decide to use a transmitter in the outdoor area,
choose a shady and dry place. Direct sunlight may trigger incorrect measurement and continuous humidity
damages the electronic components needlessly.
• Place the base station in any room of the house.
• Avoid the vicinity of radiators, other heat sources and direct sunlight.
• Keep a distance of at least 2 metres to possibly interfering sources (TV, computer, microwave, wireless phones,
baby monitors) and large metal objects (e.g. refrigerator). Within solid walls, especially ones with metal parts,
the transmission range can be reduced considerably. In extreme cases, please place the unit close to a window
to improve reception.
• Check whether the transmission from the transmitter to the base station is possible
• If necessary, choose another position for the outdoor transmitter and/or receiver.
• If the transmission is successful, you can place the base station and the outdoor transmitter or wall mount the
transmitter with the suspension device.
