Compass Mode
- In the Compass Mode, the 1st row of the display
s h o w s t h e b e a r i n g ( c o m p a s s p o i n t s ) o f t h e
direction which the watch's pointer is pointing.
- The 2nd row of the display shows the bearing
(digital) of the direction which the watch's pointer is
pointing.
- The 3nd row of the display shows the current time: hour,
minute and second.
- The indicators encircled the display show the direction
of magnetic North analogically.
- In the Compass Mode, the Compass Mode will change
to the standby mode after 1 minute.
- In the standby mode, press any button except
[Light] button once to return to Compass Mode.

What is Magnetic Declination
- The angular difference between Magnetic North Pole and
True North Pole is called magnetic declination. Its
amount (degrees and minutes) and direction (easterly
and westerly) depend on where you are.
- HandHeld TrackMaster also includes a compensation
setting

Magnetic Declination Information
- Most topographic maps shown magnetic north pole and or
the magnetic declination information.
- This manual includes the magnetic declination for some
major cities. Check the 'Magnetic Declination at
Major Cities' section for more detail.
- For those cities whose names are not included in the list,

different from the True North Pole. The HandHeld
TrackMaster, like most magnetic compass, points to the
Magnetic North Pole. On the contrary, everything measure
from a map is related to the True North Pole.
- For serious compass user or who intends to perform
accurate navigation, compass must be adjusted to
compensate of magnetic declination.

Magnetic Declination Compensation
- Compensate an object's bearing by subtract westerly
( W ) m a g n e t i c d e c l i n a t i o n o r a d d e a s t e r l y ( E )
magnetic declination with the magnetic bearing.
Example 1
needle points 323  .
- The bearing will be 323

(MB) - 23

(W) = 300

(TB).
Example 2
- 22  Easterly magnetic declination and the compass
needle points 278

.
- The bearing will be 278

(M) + 22

(E) = 300

(TB).
- HandHeld TrackMaster will compensate the compass
bearing wherever the magnetic declination is either
Westerly (-ve) declination or Easterly declination (+ve)
automatically, if the user input the magnetic declination
angle of the city which close to the user's current location
into the watch during the calibration.
- Check the 'Calibrating the Compass' section for more
detail of the calibration.
