User manual GEONAUTE COMPASS C200

[. . . ] 3. The compass detects MAGNETIC north, which is not in exactly the same place as Geographic north. The difference (declination) depends on the position of the user on the globe and is given by the following table. Declination values for a few major cities around the world. For your city, use an average value between 2 nearby cities. [. . . ] B. I know where I am and I have taken the bearing (angular direction) to follow. how do I determine my position on the map?How do you measure distances on the map? EN Explanation of each operating mode A. Determining an angular direction (Azimuth) on a map (I am at position A and I must go to B - which azimuth should I follow?). 1. Position yourself on a flat, level spot. Mark the departure point (A) and the arrival point (B) on the map. 2. Turn the dial of the compass in such a way as to align the red line (3) with the direction-of-travel arrow of the compass (1). Orient the compass by aligning the needle of the compass and the North of the graduated scale of the dial. Turn the map without changing the orientation of the compass and orient the North of the map towards the North indicated by the compass needle. 4. Keeping the map pointing North, turn the plate of the compass without changing the position of the dial (red needle and red line aligned). Bring the directionof-travel arrow of the compass (1) to the direction (AB) to be measured. 5. Take the bearing (the angle formed by the direction to be measured and magnetic north) on the graduated scale of the dial (i. e. 340°) at the position marked by the white line in the direction-of-travel arrow. Now you know which direction to take. . . B. How do you get to point B from point A, which you have found on the map? 10 NOTICE_C200 TLL 9/08/06 12:17 Page 11 1. In preparation: mark points A and B on the map. Draw a straight line between the two (AB). Turn the map and orient the north of the map towards the magnetic north indicated by the compass. 3. Without moving the map, turn the whole compass to align its direction-oftravel arrow with the line (AB) to be measured. 4. Rotate the dial without moving the plate until the magnetic needle is lined up with the red marking of the capsule and the 0 of the scale marks. Read the bearing (AB) at the intersection of the scale and the direction-of-travel arrow of the compass. 5. Without changing anything, now you simply head in the direction of the direction-of-travel arrow of the compass, keeping the compass flat and the needle over the red marking of the capsule. C. [. . . ] Draw a straight line, passing through R2. 7. Your position is thus at the intersection of the two bearings on the map. 8. We strongly recommend that you repeat the procedure a 3rd time with a third landmark (R3) for greater safety. Now you know where you are. 11 NOTICE_C200 TLL 9/08/06 12:17 Page 12 D. [. . . ]
