Hand Home Position Adjustment

Strong magnetism or impact can cause the hands of the watch to be off.

•Home position adjustment is not necessary when the analog time and digital time are the same time in the Timekeeping Mode.

To adjust home positions

1. In the Timekeeping Mode, hold down Aand keep it depressed for about five seconds until H.SET appears on the upper display.

• When you release Aafter H.SET appears, the second hand will move

to 12 o’clock. This indicates the second hand home position adjustment

mode.

• Though ADJ will appear in the upper display about two seconds after you hold down A, do not release the button yet. Keep it depressed until H.SET appears.

	• Use the Dbutton to select a hand for adjustment. Each press of D
	cycles in sequences from the second hand, to the hour and minute hands,
	and then the mode dial hand. Selecting a hand causes it to move to 12
	o’clock and the content of the lower display changes as shown in the table
	below.
Lower display	Selected hand
Flashing 00	Second hand
Flashing 0:00	Hour and minute hands
Flashing Sub	Mode dial hand

• If the selected hand does not move exactly to 12 o’clock, perform step 2 below to adjust it.

SW				NE
SSW				ENE
S				E
180	SSE	SE	ESE	90

To perform a digital compass operation

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.In any mode (except a setting mode), press Cto perform a digital compass operation.

•This will cause the mode dial hand to move to COMP.

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

•See “Digital Compass Readings” (page E-21) for information about how direction readings are indicated by the watch.

Note

•If there is an angle value in the upper display, it means that the

bearing memory record (page E-26) is displayed. If this happens, press Eto exit the bearing memory record.

4.To return to the mode you were in immediately before entering the Digital Compass Mode, press D. To enter the Timekeeping Mode, hold down Dfor at least two seconds.

E-20

•Note that performing a digital compass operation while the watch is not horizontal (in relation to the horizon) can result in large error.

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

•Any ongoing digital compass 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 digital compass operation resumes for its remaining duration after the operation that caused it to pause is finished.

•See “Digital Compass Precautions” (page E-33) 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 two different bearing sensor calibration methods: bidirectional calibration or magnetic declination correction.

• Bidirectional Calibration

Bidirectional calibration calibrates 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.

Important!

The more correctly you perform bidirectional calibration, the better the accuracy of the readings produced by the bearing sensor. 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.

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

Note

•For information about selecting a Home City and configuring the DST setting, see “Configuring Home City Settings” (page E-13).

•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 battery replaced.

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

•Refer to the pages shown below for more information on Timekeeping Mode settings.

-Button operation tone on/off: “To enable or disable the button operation tone” (page E-52)

-Illumination duration setting: “To change the illumination duration” (page E-48)

E-17

•The watch will return to regular timekeeping automatically if you do not perform any operation for about two or three minutes. Any changes you have made to settings up to that point will be saved.

2.Use E(+) and B(–) to adjust the position of the currently selected hand.

•Holding down either button will cause the hand to move at high speed. Once started, high-speed hand movement will continue even if you release the button. To stop high-speed hand movement, press any button.

•The second hand and mode dial hand will automatically stop high-speed movement after they complete one revolution. The minute hand will stop automatically after 12 revolutions.

3.Press Ato exit home position correction and return to regular timekeeping.

Note

After performing home position adjustment, enter the Timekeeping Mode and check to make sure that the analog hands and the lower display indicate the same time. If they do not, perform home position adjustment again.

E-19

Digital Compass Readings

•When you press Cto start a digital compass operation, COMP will initially appear on the upper display. About two seconds after you start a digital compass operation, an indicator will appear in the upper display to indicate what direction the 12 o’clock position of the watch is pointed. The second hand will point to magnetic north.

•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, the digital compass operation will stop automatically.

•The direction indicator and angle value will show - - - to indicate that the digital compass operation is 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 upper display.

	Direction	Meaning	Direction	Meaning	Direction	Meaning	Direction	Meaning
	N	North	NNE	North-	NE	Northeast	ENE	East-
				northeast				northeast
	E	East	ESE	East-	SE	Southeast	SSE	South-
				southeast				southeast
	S	South	SSW	South-	SW	Southwest	WSW	West-
				southwest				southwest
	W	West	WNW	West-	NW	Northwest	NNW	North-
				northwest				northwest

•The margin of error for the angle value and the direction indicator is ±15 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 300 to 330 degrees.

E-21

• 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 A.

• The second hand will move to 12 o’clock, indicating the

bidirectional calibration mode.

• At this time the upper display will show an upward pointing arrow () and the lower display will show -1-. These indicate that the watch is ready for calibration of the first direction.
