I do press the upper left button to start the
compass, if the display tells me to do so. I posed my
CORE on a bottle to keep it horizontally while turning. I can turn to neither direction in more than 15 sec per turn. I did start up to turn it clockwise.
Always the "start
compass" lights up again.
Is this the (hidden) sign that calibration has taken effect?
This is my second
CORE, the first one didn't respond to any button after 1 week. Exchange via after sales was made in 10 days.
So never the less: is it broken again??? Any one out there finding same troubles?
What is the message if compensation is done correctly?. Instructions on Handbook are very very very poor on this item!

 | Compass |  | Compasses are sensitive, absolutely crucial instruments to precision navigation. The earth's magnetic field, inclination, and your longitude and latitude all influence the horizontal plane of a compass needle. As a result, compasses are balanced for different geographical zones. Suunto Compasses overcome this limitation to traditional compasses by using a simple 'Two Zone System'. With a Suunto Compass, the only 'balancing zones' are the northern and southern hemispheres. In addition to this innovation, certain Suunto Compasses come equipped with useful features like luminous needles and marks, centimeter/inch scales, magnifying glasses, clinometers, sighting notches, and more. | |  |
