USER GUIDE
GETTING STARTED
Thank you for purchasing this Swiss-designed and Swiss-
manufactured wind instrument. To obtain the best results,
please read the instructions and follow the usage precautions.
This instrument is designed as an aid to users who are in an
open-air environment, but IT CANNOT replace advice and
warnings from the local weather station.
Open-air climatic conditions can sometimes change quite
dramatically, and this can happen very quickly indeed. Sunny
weather can, for example, change to thunderstorm conditions
in the space of half an hour and sometimes less. You should
therefore always follow basic safety rules whenever you
undertake open air activity.

MAINTENANCE
The design and manufacture of this instrument have been the
subject of a great deal of care. To make best use of the
proposed functions you are advised to use the instrument in
accordance with the following observations:
• Avoid at all costs items such as hair, thread, sand or other
dust materials getting into the impeller, as they could cause
defective rotation of the impeller and therefore a loss of
precision. If a hair or a piece of thread should manage to get
into the impeller, extract it gently using tweezers; in the
case of dust or sand, you can run clean water over the
impeller.
• Avoid touching the temperature sensor.
• Avoid exposing the instrument to extreme climatic
conditions for over-long periods. While it uses components
resistant to such temperatures, we recommend that you do
not expose your instrument to strong sources of heat, for
example under the windscreen of a vehicle.
• Avoid careless use or sharp impacts.
• DO NOT EXPOSE the instrument to powerful chemicals.
Such products could damage it.
