ly 2 minutes.

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 respec-
tive location by the hanging hole at the back of the unit.
Avoid the vicinity of any interfering field like computer mon-
itors 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 respec-
tive location by the hanging hole at the back of the unit.
Choose a shady and dry position for the transmitter. (Direct
sunshine falsifies the measurement and continuous humidity
strains the electronic components needlessly).
•
Check the transmission of 433 MHz signal from the transmit-
ter to the display unit (transmission range 30 m free field).
Within ferro-concrete rooms (basements, superstructures),
the received signal is naturally weakened.
