1. Open the radiosonde package and remove the radiosonde from the package. 
The foil bag contains illustrated instructions for preparing the radiosonde.
2. Place the radiosonde on RI41 carefully. The radiosonde is automatically switched on
when placed on RI41. Make sure that the radiosonde sensor boom does not hit the
support plate on RI41 as this might damage the sensor boom.
