Thermo Hygro Sensor after batteries are inserted. If the reception of outdoor values fails,
“- -“ appears on the display. Check the batteries and try it again. Check if there is any
source of interference. Manual initialization by pressing the ▲ button of the display unit
for 2 seconds can be helpful.
• Press “°C /°F” button on the thermo sensor unit to select Celsius mode or Fahrenheit
mode for the Thermo Sensor display.
• Press RESET to re-start in case of problems.
• After successful installation screw up the battery compartment of transmitter carefully.
4. Positioning of transmitter
• Choose a shady and dry position for the transmitter. ( Direct sunshine falsifies the
measurement and continuous humidity strains the electronic components needlessly)
• Avoid the vicinity of any interfering 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 60 m free field). Within ferro-concrete rooms (basements,
superstructures), the received signal is naturally weakened.
• If necessary chose another position for transmitter.
• Fix the transmitter by using plastic hanger.
5. Battery replacement
• When the batteries are used up, low battery icon appears at the indoor or outdoor
temperature row of the display unit.
• Use alkaline batteries 1.5 V AA only. Observe correct polarity. Attention: Do not dispose
of empty batteries in household waste. Take them to special local collection sites.
6. Notes
l Always read the users manual carefully before operating the unit.
l Avoid placing the clock near interference sources/metal frames such as computer or TV
sets.
l Do not expose the instrument to extreme temperatures, vibration or shock.
