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 close

est

your current location

- Perform the compass calibration

n the following

conditions:

1) when the

XG-

is used the first time,

2)when the '

DIST

indicator is flashing,

3) the battery has been replaced,

when

ing

the compass in a location

different

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

has a

ppeared.

Example 1:

- Compensate the magnetic declination for Wellington in

New Zealand (22-E), 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
' R o t a t i o n ' M o d e , t h e E L b a c k l i g h t w i l l t u r n o n

automatically for a second. At the same time, the '

CAL

indicator will

show

on 1st row of the display and

the bearing indicators

will

start to move.

When the EL back light is off, hold the

XG-20

on a

flat surface which is parallel to the horizon, then rotate

the

XG-20

clockwise at the rate as the bearing

indicators' moving for 2 turns. The rotation should be
completed in a

slow and steady practi

- When the turning is completed, press [mode] button to
return to Compass Mode. 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

XG-20

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 f f e r e n c e b e t w e e n N o r t h a n d t h e

object. (Assuming that 0 for North, and the 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 . The
digital bearing direction of object D from point A is

315 .
