Suunto Ambit3 Run has a digital compass that allows you to orient yourself in relation to magnetic north. The tilt-compensated compass gives you accurate readings even if the compass is not horizontally level.
You can show/hide the compass display from the options menu while in a sport mode under ACTIVATE » Compass.
The compass display includes the following information:
The compass switches to power saving mode after one minute. Reactivate it with.
To ensure correct compass readings, set an accurate declination value.
Paper maps point to true north. Compasses, however, point to magnetic north – a region above the Earth where the Earth’s magnetic fields pull. Because magnetic North and true North are not at the same location, you must set the declination on your compass. The angle in between magnetic and true north is your declination.
The declination value appears on most maps. The location of magnetic north changes yearly, so the most accurate and up-to-date declination value can be obtained from the internet (for example www.magnetic-declination.com).
Orienteering maps, however, are drawn in relation to magnetic north. This means that when you are using orienteering maps you need to turn the declination correction off by setting the declination value to 0 degrees.
To set the declination value:
You can also access the compass settings by keeping Compass mode.pressed in
If you have not used the compass before, you must first calibrate it. Turn and tilt the watch in multiple directions until the watch beeps, indicating calibration is complete.
If you have already calibrated the compass and want to re-calibrate it, you can access the calibration option in the options menu.
If the calibration is successful, the text Calibration successful is displayed. If the calibration does not succeed, the text Calibration failed is displayed. To retry the calibration, press .
To manually start compass calibration:
You can mark the direction to your target in relation to North with the bearing lock feature.
To lock a bearing:
While using the compass in an exercise mode, thebutton only locks and clears the bearing. Exit the compass view to make a lap with .
