4.5.7.2 MAGNETIC VARIATION (DECLINATION) (PIC. 042)
Here is where you set the local magnetic variation (declination). Available alternatives are MAN (manual adjustment)
and AUTO (automatic adjustment). Magnetic variation (declination) is the local difference between the direction to
the Geographic North Pole and the direction to the Magnetic North Pole to which all magnetic compasses point.
Since most maps use Geographic North as north reference and a magnetic compass points in a slightly different
direction you should compensate for that in order to get compass directions that are correct compared to bearings
on the map.
Normally you can find information about the local magnetic variation (declination) on your map. If you want to set it
manually, you select MAN and enter the amount of the variation (declination) in degrees and if it is Easterly or
Westerly.
Intellicompass
TM
: The Multi-Navigator
TM
has a built-in, very advanced, magnetic model which calculates the local
magnetic variation (declination) automatically by using the GPS position. If you at all are unsure of the amount of
the magnetic variation we recommend you select AUTO.
4.5.7.3 DEVIATE COMPASS
In order to obtain the highest possible accuracy from the built-in electronic compass, it is very important that you
adjust the compass for deviation. We recommend you do it at least every time you change the batteries.
Place the Multi-Navigator
TM
on a non-magnetic and horizontal surface and press YES. When the text AUTODEV
ROTATE SLOWLY appears - take about twenty seconds to rotate the unit 400 degrees. When the rotation is
completed, the text ”AUTODEV SUCESSFULL” tells you that it has been done correctly and that the compass is
ready to use. If AUTODEV FAILED appears just enter the function again and try once more. Tip! If you are in the
outdoors, do the deviation by holding the unit horizontally in your hand (check the bubble level) and turn yourself
400 degrees until the deviation is done correctly.

5. PRACTICAL NAVIGATION EXAMPLE
Here we will show you, step by step, a practical example of how you can use your Multi-Navigator
TM
in practise.
5.1 The fishing trip to the lake
In this example we are going to fish in a lake we have never been to before. We have a topographic map of the area
and we will drive by car to the spot where the road ends. We know the way to the end of the road but we want to
use the Multi-Navigator to find the lake and also to find our way back to the car.
5.1.1 How to enter the lake as a waypoint in the Multi-Navigator
TM
First of all we determine the position of the lake by using the co-ordinates on the map. (FIG. 043) This map uses
