DocumentDocumentUSER GUIDE GETTING STARTED Thank you for purchasing this Swiss-designed and Swissmanufactured 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. SKYWATCH WIND KEY FEATURES Wind impeller Beaufort scale Temperature sensor Wind units On/Off Mode select Temperature units Lanyard SWITCHING ON To switch on the SKYWATCH® Wind press briefly on the button. The instrument switches on and displays the software version after which the instrument enters the last mode displayed before the instrument was switched off (for firsttime use this defaults to actual and maximum wind speed. SWITCHING OFF Switching off automatically (Auto-off) The SKYWATCH® Wind switches off automatically one minute after either the button was last pressed or after the last nonzero wind speed measurement. Switching off manually To switch the SKYWATCH® Wind off manually (valid in every mode), hold the button depressed until the display flashes briefly and it switches off, then release. DISPLAY MODES Momentary pressure on the button allows you to move between the display modes Modes 1. Wind + maximum wind speed 2. Wind + lifetime maximum wind speed 3. Wind + temperature 4. Wind + wind chill (perceived temperature) Symbol key Wind chill Maximum wind Lifetime wind MEASUREMENT Selection of wind units (modes 1 & 2) Switch between units by repeated longer button presses whilst observing the LCD display: km/h (kilometers per hour), mph (miles per hour) knots (nautical miles per hour) and m/s (meters per second). When the unit of choice appears, release the button. Selection of temperature units (modes 3 & 4) Switch between units by repeated longer button presses whilst observing the LCD display: °C or °F. When the unit of choice appears, release the button. Wind speed Maximum wind speed is measured since the last power-on; Lifetime maximum wind speed is measured since the last manual reset (holding the power button for longer than two seconds resets it to zero). For the measurement to be as exact as possible align the instrument along the axis of the wind. ©JDC Electronic SA, all rights reserved.

Please ensure that the unit is correctly recycled in accordance with the applicable regulations. 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. JDC ELECTRONIC SA Avenue des Sports 42 1400 Yverdon-Les-Bains Switzerland info@jdc.ch www.jdc.ch ©JDC Electronic SA, all rights reserved.
