Operating Instructions
Switching on and off:
The probe measures radon concentration autonomously and communicates in wireless network only if
the switch is in position
„I“(
switch on).
The switching on is signalized by LED diode „STAT“ according chart
below.
If the switch is in position
„0“ (
switch off) the probe doesn
´
t measure radon concentration and doesn
´
t
communicate in wireless network. In switching off mode the probe only keeps running real time for correct
date and time of records in case of switch it on again. By switching off the probe doesn
´
t lose previous
records of measurement.
The switching on is signalized by LED diode „STAT“ according chart below.
It is possible to download data from probe over USB in both position of switch.
