Precautions for using the Compass
• Keep your Watch away from magnets or any appliances
which may contain magnetic objects such as mobile
phones, speakers, motors and etc.
• The Watch, like most magnetic compass, points to the
magnetic north which is slightly different from the true
north. Check the 'What is Magnetic Declination' section
for more details.
• Perform the compass calibration from time to time,
because the calibration can ensure the precision of the
compass.
• To achieve an accurate result, you should avoid
measuring direction on the following conditions:
1) The watch is placed close to the magnetic objects.
2) The watch is placed close to the metal objects.
3) The watch is placed close to the electrical
appliances.
4) The watch is placed inside a moving object or a
ferroconcrete building.
The Direction of an Object
• The direction of an object from a point can be specified
in either compass directions or bearing directions.
• The Watch includes both compass directions and
bearing directions.
The Compass Directions
• The compass directions are shown in the adjacent
table.
• For example, in the figure on the left, the compass
direction of object B from point A is due East. The
compass direction of object C from point A is Southeast.
The compass direction of object D from point A is
Northwest.
The Bearing Directions
• The Bearing direction of an object is defined as the
angular difference between North and the object.
(Assume 0°for due North, and the measuring range is
from 0° to 359°).
• For example, in the figure on the left, the bearing
direction of object B from point A is 90°. The bearing
direction of object C from point A is 135°. The bearing
direction of object D from point A is 315°.
Check your position by Backward Bearing Directions
• Spot two distant identifiable landmarks like mountains,
light-house, fort or building from yourcurrent position, for
example the mountains A and B.
• Check out the backward bearing directions of mountains
A and B from your current position, for example 135°
from mountain A and 270° from mountain B.
• Use a ruler to draw a line 135° from the north at the
mountain A to your current position on the map. Draw
another line 270° from the north at the mountain B to
your current position on the map.
• Your current position on the map will be the intersection
(point A) of the lines 135° from the mountain A and 270°
from the mountain B.
The Compass Directions
• During a trekking, the Watch can keep your course in a
correct way. For example, the correct trail starts from
point A and finishes at point E as drawn on the adjacent
map.
• Mark the points (identifiable landmarks) where the trail
turns its direction or the trail branches its way, such as
the points A, B, C, D and E on the adjacent map.
• Find out the bearing directions of point B from point A
(315°), point C from point B (0°), point D from point C
(225°), and then point E from point D (315°).
• During the trekking, make sure that the heading
direction is 315° from point A to point B. Performing the
similar checking in other sections of the trail helps you
keep your course correctly.
MPORTANT: If you are in doubt of the directions and
positions of the trail, consult the park administration office
before starting the trekking.
Compass Mode
• In the Compass Mode, the top row of the display shows
the bearing direction.
• The middle row of the display shows the compass
direction.
• The bottom row of the display shows the current time in
hour and minute.
• The pointer encircled the display shows the direction of
magnetic North analogically.
IDLE Mode
• If no key is pressed for about 1 minute, the watch will go
to the IDLE Mode automatically. To activate the
compass again, press any button.
Distortion
• If distortion is detected, the bearing direction will flash.
• Please refer to the coming section "Calibrating the
Compass" to restore the compass to normal operation
when distortion is detected.
