T-TOUCH SOLAR E84 COMPASS > CALIBRATION 2 sec. Compass calibration display Activate calibration mode - glass deactivated during calibration Turn the watch more than a complete revolution on a horizontal surface (e.g. a table) in an environment free from magnetic interference, at a rotation speed of around 30° per second. Total time: 20 seconds maximum a) Calibration successful - data stored b) Calibration failed - repeat calibration Back to compass display COMPASS > GLOSSARY Compass In compass mode, your T-TOUCH SOLAR E84 indicates the True North Pole, factoring in magnetic declination. Compass explanations The vertical lines (meridians) on the Earth converge at the True North Pole (Ng), indicating its direction. The hand of a conventional compass indicates the direction of the Magnetic North Pole (Nm). The angle (α) between these two directions Ng and Nm is known as magnetic declination. The magnetic declination value depends on your location on Earth. Furthermore, the Magnetic North Pole is constantly moving. So the magnetic declination value also depends on the date. If the correct magnetic declination value (for the location and date) is set (see the setting procedure on page 15), the minute hand of your T-TOUCH SOLAR E84 will point to True North (Ng). If the magnetic declination is set to 0, your T-TOUCH SOLAR E84 will point to Magnetic north (Nm). The magnetic declination values and dates are indicated on topographic charts, or can be found using special software available on the Internet. For the whole world:http://www.ngdc.noaa.gov/ Azimuth In azimuth mode, your T-TOUCH indicates the azimuth heading you should take. Azimuth explanations The azimuth is the horizontal angle between the direction of an object and True North. The azimuth is measured from north in degrees from 0° to 359° (e.g.: East = 90°). In azimuth mode, the T-TOUCH emits a beep and visual signal when the 6-12 o'clock axis of the watch is aligned with the azimuth heading set. Heading Azimuth 315o Azimuth 315o 12 o'clock represents the azimuth heading relative to True North. Note 1 For a correct indication of North, it is extremely important to hold the watch as level as possible. Note 2 The compass function, like any other compass, should not be used near a metal or magnetic object. In case of doubt, you can recalibrate your compass.
