Taking Direction Readings

In the Digital Compass Mode, a built-in bearing sensor detects magnetic north at regular intervals and indicates one of 16 directions on the display.

4.After all of the settings are the way you want, press E to exit the setting screen.

• To return to the screen in step 1, press E again.

Note

•For information about selecting a Home City and configuring the DST setting, see “Configuring Home City Settings” (page E-28).

•While the 12-hour format is selected for timekeeping, a P (PM) indicator will appear for times from noon to 11:59 p.m. No indicator appears for times from midnight to 11:59 a.m. With 24-hour format, time is displayed from 0:00 to 23:59, without any P (PM) indicator.

•The watch’s built-in full automatic calendar makes allowances for different month lengths and leap years. Once you set the date, there should be no reason to change it except after you have the watch’s rechargeable battery replaced or after power drops to Level 5 (page E-10).

•The day of the week changes automatically when the date changes.

To take a digital compass reading

1.Make sure the watch is in the Timekeeping Mode or any one of the sensor modes.

•The sensor modes are: Digital Compass Mode, Barometer/ Thermometer Mode, and Altimeter Mode.

2.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).

3.Point the 12 o’clock position of the watch in the direction you want to measure.

4.Press C to start digital compass measurement.

•COMP will appear on the display to indicate that a digital compass operation is in progress.

•See “Digital Compass Readings” on page E-35 for information about what appears on the display.

Note

•If there is a value directly below the current time (center right of the

display), it means that the bearing memory screen (page E-40) is displayed. If this happens, press E to exit the bearing memory screen.

magnetic north, south, east, and west will also 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.

5.After you are finished using the digital compass, press D to return to the Timekeeping Mode. E-34

•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 L). The measurement operation resumes for its remaining duration after the operation that caused it to pause is finished.

•See “Digital Compass Precautions” (page E-46) 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. You can use any one of three different bearing sensor calibration methods: bidirectional calibration, northerly calibration, or magnetic declination correction.

•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).

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-36

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 C again to calibrate the second direction.

E-35

•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°.

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.

To perform bidirectional calibration

1. In the Digital Compass Mode, hold down E until SET Hold appears on the display and then the magnetic declination settings start to flash.

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.

E-37

4.Press C to start the calibration operation.

•- - - is shown on the display while calibration is being performed. When calibration is successful, the display will show OK and then change to the Digital Compass Mode screen.

direction value (E, W, or OFF)

 

• - - - is shown on the display while calibration is being performed. When calibration is successful,

the display will show OK and then change to the Digital Compass Mode screen.

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 Mode, hold down E until SET Hold appears on the display and then the magnetic declination settings start to flash.

2. Press D twice to display the northerly calibration screen.

• At this time, -n-(north) appears on the display.

3. Place the watch on a level surface, and position it so that its 12 o’clock position points north (as measured with another compass).

Magnetic declination angle value

2.Use A (East) and C (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 A and C 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 E to exit the setting screen.
