7.6 Positioning and fixing of the basic station and the transmitter
• With the foldable leg at the back of the basic unit it can be
placed onto any flat surface or wall mounted at the respective
location by the hanging hole at the back of the unit. Avoid the
vicinity of any interfering field like computer monitors or TV sets
and solid metal objects.
• With the foldable leg at the back of the transmitter it can be
placed onto any flat surface or wall mounted at the respective
location by the hanging hole at the back of the unit. Choose a
shady and dry position for the transmitter. (Direct sunshine fal-
sifies the measurement and continuous humidity strains the
electronic components needlessly).
• Check the transmission of 433 MHz signal from the transmitter
to the display unit (transmission range 30 m free field). Within
ferro-concrete rooms (basements, superstructures), the re-
ceived signal is naturally weakened.
