Check your position by Backward Bearing
- The XG-20 can check your position by backward
bearing.
- Spot two distant identifiable landmarks (mountains,
light- houses, forts and buildings) of your current
position, such as the mountain A and B.
- Consult a map to find out the mountain A and B's
locations on a map.
- Check out the backward bearing directions of mountain
A and B of your current position, such as 135 8 for
mountain A and 270 8 for mountain B.
- Use a ruler to draw the line 135 8 on the map which
starting from the mountain A. Draw the line s 270 8 on
the map which starting from the mountain B.
- Your current position will be at the intersection point
(point A) of the lines 135 8 and 2708.

Measure Compass Directions
- When measuring compass directions, make sure
that the XG-20 is placed on a flat surface
which is parallel to the horizon.
- If you are wearing the XG-20 during the
m e a s u r e m e n t , m a k e s u r e t h a t y o u r w r i s t i s

be inaccurate.
- Point the pointer which is engraved on the watch in
the direction where your target object is.
- Press the [Compass] button once to select the
Compass Mode, in the Current Time Mode.
- The Compass points of the target object appears on
the 1st row of the display. The digital bearing
direction of the target object appears on the 2nd r o w
