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 an
open-air activity.

MAINTENANCE
The design and manufacture of this instrument have been the subject of a great deal of care. To make the 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.
IMPELLER REPLACEMENT
To replace the impeller gently remove the rear support using a pair of fine
pliers. Insert the new impeller so the magnet is facing the rear of the unit.
Gently press the rear support back into place. Avoid touching the sharp
impeller shaft.
