To Calibrate the compass
IMPORTANT : If the watch has not been calibrated, the
direction reading may be inaccurate.
- Check the 'Magnetic Declination at Major Cities' section
to get the magnetic declination of the city which close to
your current location, because such angle will be
i n p u t t e d i n t o t h e H a n d H e l d Tr a c k M a s t e r d u r i n g t h e
c a l i b r a t i o n .
- Perform the compass calibration on the following
conditions:
1) when the HandHeld TrackMaster is used the first time,
2) when the ' DIST' indicator is flashing,
3) the battery has been replaced, and
4) use the compass in a location where is apart from the
place in which the compass had been calibrated.
To Calibrate the Compass
- Press and hold the [mode] button for 2 seconds to
start the Magnetic Declination Setting, in the Compass
Mode.
- The ' DEC ' indicator will be appeared on the 1st row of
the display. The digit will start flashing, press the
[start/stop] button to change the angle (from -90 to
90) until the desire magnetic declination appeared.
Example 1:
- Compensate the magnetic declination for Wellington in
New Zealand (22-E), select +22 in the magnetic
declination setting.
Example 2:
- Compensate the magnetic declination in Boston in the
USA (16-W), select -16 in the magnetic declination
setting.
- Press the [mode] button to go to the Calibration
'Rotation' Mode, the EL back light will turn on
automatically for a second. At the same time, the '
CAL '
indicator will be appeared on 1st row of the display and
the bearing indicators start to move.
- When the EL back light is off, hold the HandHeld
TrackMaster on a flat surface which is parallel to the
horizon, then rotate the HandHeld TrackMaster clockwise
at the rate as the bearing indicators' moving for 2 turns.
The rotation should be completed in a slow and steady way
.
- When the turning is completed, press the [mode] button
to return to Compass Mode otherwise the Calibration
'Rotation' Mode will return to Compass Mode after 1
minute.

The Direction of an Object
- The direction of an object from a point is specified in
either compass points or digital bearing directions.
- The HandHeld TrackMaster provides both compass
points or digital bearing directions.
The Compass Points
- The compass points are North, Northeast, East.
Southeast, South, Southwest, West and Northwest.
- For example, in the figure on the left, the compass
points of object B from point A is East. The compass
points of object C from point A is Southeast. The
compass points of object D from point A is Northwest.
The Digital Bearing
- The digital bearing direction of an object is defined as
t h e a n g u l a r d i ff e r e n c e b e t w e e n N o r t h a n d t h e
o b j e c t . ( A s s u m i n g t h a t 0 f o r N o r t h , a n d t h e
measuring range is from 0 to 359 )
- For example, in the figure on the left, the digital bearing
direction of object B from point A is 90 . The digital
bearing direction of object C from point A is 135 . T h e
digital bearing direction of object D from point A i s
315 .
