To take a digital compass reading

1. Place the watch on a flat surface. If you are wearing 

the watch, make sure that your wrist is horizontal (in 
relation to the horizon).

2. Point the 12 o’clock position of the watch in the 

direction you want to check.

3. Press 

C

 to enter the Digital Compass/Thermometer 

Mode and take a digital compass reading.

COMP

 will appear on the display to indicate that a 

digital compass operation is in progress.

 See “Digital Compass Readings” on page E-51 for 

information about what appears on the display.

Note

 If a value appears to the right of the direction 

indicator, it means that the bearing memory (page 
E-61) screen is displayed. If this happens, press 

A

 to exit the bearing memory screen.

Digital Compass Readings

 When you press 

C

to start digital compass measurement, 

COMP

 will appear on 

the display initially to indicate that a digital compass operation is in progress.

 About two seconds after you start a digital compass measurement operation, letters 

on the display will indicate the direction that the 12 o’clock position of the watch is 
pointing. Four pointers that indicate magnetic north, south, east, and west also will 
appear.

 After the first reading is obtained, the watch will continue to take digital compass 

readings automatically each second for up to 20 seconds. After that, measurement 
will stop automatically.

 The direction indicator and angle value will show 

- - -

 to indicate that digital 

compass readings are complete.

 The auto light switch is disabled during the 20 seconds that digital compass 

readings are being taken.

 The following table shows the meanings of each of the direction abbreviations that 

appear on the display.

 The margin of error for the angle value and the direction indicator is ±11 degrees 

while the watch is horizontal (in relation to the horizon). If the indicated direction is 
northwest (

NW

) and 315 degrees, for example, the actual direction can be 

anywhere from 304 to 326 degrees.

E-53

 Note that taking a measurement while the watch is not horizontal (in relation to the 

horizon) can result in large measurement error.

 You can calibrate the bearing sensor if you suspect the direction reading is 

incorrect.

 Any ongoing direction measurement operation is paused temporarily while the 

watch is performing an alert operation (daily alarm, Hourly Time Signal, countdown 
timer alarm) or while illumination is turned on (by pressing 

B

). The measurement 

operation resumes for its remaining duration after the operation that caused it to 
pause is finished.

 See “Digital Compass Precautions” (page E-70) for important information about 

taking direction readings.

Calibrating the Bearing Sensor

You should calibrate the bearing sensor whenever you feel that the direction readings 
being produced by the watch are off. There are three different calibration methods 
available: magnetic declination correction, bidirectional calibration, and northerly 
calibration.

E-54

 Magnetic Declination Correction

With magnetic declination correction, you input a magnetic declination angle 
(difference between magnetic north and true north), which allows the watch to 
indicate true north. You can perform this procedure when the magnetic declination 
angle is indicated on the map you are using. Note that you can input the declination 
angle in whole degree units only, so you may need to round off the value specified on 
the map. If your map indicates the declination angle as 7.4°, you should input 7°. In 
the case of 7.6° input 8°, for 7.5° you can input 7° or 8°.

 Bidirectional Calibration and Northerly Calibration

Bidirectional calibration and northerly calibration calibrate the accuracy of the 
bearing sensor in relation to magnetic north. Use bidirectional calibration when you 
want to take readings within an area exposed to magnetic force. This type of 
calibration should be used if the watch becomes magnetized for any reason. With 
northerly calibration, you “teach” the watch which way is north (which you have to 
determine with another compass or some other means).

E-55

Important!

The more correctly you perform bidirectional calibration, the better the accuracy of 
the bearing sensor readouts. You should perform bidirectional calibration whenever 
you change environments where you use the bearing sensor, and whenever you feel 
that the bearing sensor is producing incorrect readings.

E-56

To perform magnetic declination correction

1. In the Digital Compass/Thermometer Mode, hold down 

A

 until the current magnetic declination settings start 

to flash on the display. This is the setting screen.

2. Use 

E

 (East) and 

B

 (West) to change the settings.

 The following explains magnetic declination angle 

direction settings.

OFF

: No magnetic declination correction performed. 

The magnetic declination angle with this 
setting is 0°.

E

:

When magnetic north is to the east (east 
declination)

W

:

When magnetic north is to the west (west 
declination)

 You can select a value within the range of W 90° to 

E 90° with these settings.

 You can turn off (

OFF

) magnetic declination 

correction by pressing 

E

 and 

B

 at the same time.

 The illustration, for example, shows the value you should input and the direction 

setting you should select when the map shows a magnetic declination of 1° 
West.

3. When the setting is the way you want, press 

A

 to exit the setting screen and take 

direction and temperature readings.

Precautions about bidirectional calibration

 You can use any two opposing directions for bidirectional calibration. You must, 

however, make sure that they are 180 degrees opposite each other. Remember 
that if you perform the procedure incorrectly, you will get wrong bearing sensor 
readings.

 Do not move the watch while calibration of either direction is in progress.

 You should perform bidirectional calibration in an environment that is the same as 

that where you plan to be taking direction readings. If you plan to take direction 
readings in an open field, for example, calibrate in an open field.

E-58

To perform bidirectional calibration

1. In the Digital Compass/Thermometer Mode, hold down 

A

 until the current magnetic declination settings start 

to flash on the display. This is the setting screen.

2. Press 

D

 to display the bidirectional calibration screen.

 At this time, the north pointer flashes at the 12 o’clock 

position and the display will show 

-1-

 to indicate that 

the watch is ready to calibrate the first direction.

3. Place the watch on a level surface facing any direction 

you want, and press 

C

 to calibrate the first direction.

- - -

 is shown on the display while calibration is 

being performed. When calibration is successful, 
the display will show 

OK

 and 

-2-

, and the north 

pointer flashing at the 6 o’clock position. This means 
that the watch is ready for calibration of the second 
direction.

4. Rotate the watch 180 degrees.

5. Press

- - -

 is shown on the display while calibration is being performed. When 

calibration is successful, the display will show 

OK

 and then take direction and 

temperature readings.

To perform northerly calibration

Important!

If you want to perform both northerly and bidirectional calibration, perform 
bidirectional calibration first, and then perform northerly calibration. This is necessary 
because bidirectional calibration cancels any existing northerly calibration setting.

1. In the Digital Compass/Thermometer Mode, hold down 

A

 until the current magnetic declination settings start 

to flash on the display. This is the setting screen.

2. Press 

D

 twice to display the northerly calibration 

screen.

 At this time, 

-N-

 (north) appears on the display.
