Setting Up for True North Readings

(Magnetic Declination Calibration)

If you want the watch to indicate true north

instead of magnetic north, you need to specify

your current location’s magnetic declination

direction (east or west) and declination angle.

Magnetic North and True North

●

The magnetic declination angle value can

be set in 1° (degree) units only. Use a value

that is closest to the angle you want to set.

Example: For an angle of 7.4°, set 7°.

Example: For an angle of 7°40’ (7 degrees,

40 minutes), set 8°.

Note

●

Magnetic declination angles (east or

west) and angle degree values for

specific locations can be found on

geographic maps, mountain climbing

maps, and other maps that include

contour lines.

1. Enter the Compass Mode.

To stop the setting operation, press (E)

and advance to step 7.

6. Press (C).

7. Use (A) and (D) to select whether or not

you want to save your current settings.

[YES] Saves current settings.

[NO] Discards current settings.

[RETURN]

This returns to the magnetic

declination angle calibration

screen.

8. Press (C) to complete the setting

operation.

After the setting operation is complete,

[SETTING COMPLETED] will appear for

a few seconds, and then the Digital

Compass Mode setting screen will re-

appear.

9. Press (E) to exit the setting screen.

Magnetic North and True

North

There are actually two types of north:

magnetic north and true north.

Magnetic north: North indicated by the needle

of a compass

True north: Direction to the North Pole

As shown in the illustration below, magnetic

north and true north are not the same.

Earth

Magnetic north

True north

Note

●

The north indicated on commercially

available maps is normally true north.

Digital Compass Reading

Precautions

Location During Use

Taking readings near sources of strong

magnetism can cause reading error. Keep the

watch away from the following types of items.

Permanent magnets (magnetic accessories,

etc.), metal objects, high-voltage wires, aerial

wires, electrical household appliances (TVs,

computers, cellphones, etc.)

●

Note that correct direction readings are not

possible indoors, especially inside of

reinforced concrete structures.

●

Accurate direction readings are not

possible in motor vehicles, on boats, on

aircraft, etc.

Storage Location

Exposure of the watch to magnetism can

affect the accuracy of digital compass

readings. Keep the watch away from the types

of items below.

Permanent magnets (magnetic accessories,

etc.), metal objects, electrical household

appliances (TVs, computers, cellphones, etc.)
