Go to step 2.

2. Check the Home City and the daylight saving time (DST) setting.

Use the procedure under “To configure Home City settings” to configure your Home City and daylight saving time settings.

Important!

World Time Mode and Sunrise/Sunset Mode data depend on correct Home City, time, and date settings in the Timekeeping Mode. Make sure you configure these settings correctly.

3. Set the current time.

See “Configuring Current Time and Date Settings”.

The watch is now ready for use.

Charging the Watch

The face of the watch is a solar cell that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light.

Warning!

Leaving the watch in bright light for charging can cause it to become quite hot.

Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods.

•On the dashboard of a car parked in direct sunlight

•Too close to an incandescent lamp

•Under direct sunlight

Important!

•Allowing the watch to become very hot can cause its liquid crystal display to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature.

•Turn on the watch’s Power Saving function and keep it in an area normally exposed to bright light when storing it for long periods. This helps to ensure that power does not run down.

•Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is blocked from exposure to light can cause power to run down. Expose the watch to bright light whenever possible.

Power Levels

You can get an idea of the watch’s power level by observing the battery power indicator on the display.

•The flashing LOW indicator at Level 3 (L) tells you that battery power is very low, and that exposure to bright light for charging is required as soon as possible.

•At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery reaches Level 2 (M) after falling to Level 5, reconfigure the current time, date, and other settings.

•Display indicators reappear as soon as the battery is charged from Level 5 to Level 2 (M).

•Leaving the watch exposed to direct sunlight or some other very strong light source can cause the battery power indicator to show a reading temporarily that is higher than the actual battery level. The correct battery level should be indicated after a few minutes.

•All data stored in memory is deleted, and the current time and all other settings return to their initial factory defaults whenever battery power drops to Level 5 and when you have the battery replaced.

Power Recovery Mode

•Performing multiple sensor, illumination, or beeper operations during a short period may cause all of the battery power indicators (H, M, and L) to start flashing on the display. This indicates that the watch is in the power recovery mode. Illumination, alarm, countdown timer alarm, hourly time signal, and sensor operations will be disabled until battery power recovers.

•Battery power will recover in about 15 minutes. At this time, the battery power indicators (H, M, L) will stop flashing. This indicates that the functions listed above are enabled again.

•If all of the battery power indicators (H, M, L) are flashing and the C (charge) indicator also is flashing, it means the battery level is very low. Expose the watch to bright light as soon as possible.

•Even if battery power is at Level 1 (H) or Level 2 (M), the Digital Compass Mode, Barometer/ Thermometer Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available to power it sufficiently. This is indicated when all of the battery power indicators (H, M, L) are flashing.

•Frequent flashing of all of the battery power indicators (H, M, L) probably means that remaining battery power is low. Leave the watch in bright light to allow it to charge.

Power Saving

When turned on, Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving.

• There actually are two sleep state levels: “display sleep” and “function sleep”.

	Elapsed Time in Dark	Display	Operation
	60 to 70 minutes (display sleep)	Blank, with PS flashing	Display is off, but all functions are enabled.
	6 or 7 days (function sleep)	Blank, with PS not flashing	All functions are disabled, but timekeeping is
			maintained.

•The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep state.

•The watch will not enter a sleep state while it is in the Stopwatch Mode or Countdown Timer Mode.

To recover from the sleep state

Move the watch to a well-lit area, press any button, or angle the watch towards your face for reading.

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” 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 screen is displayed. If this happens, press E to exit the bearing memory screen.

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

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.

	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 ±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.

•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” 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.

• 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).

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.

To perform magnetic declination correction

Magnetic declination angle direction value (E, W, or OFF)

Magnetic declination angle value

1.In the Digital Compass Mode, hold down E until the current magnetic declination settings start to flash on the display. This is the setting screen.

•Before the magnetic declination settings start to flash, the message SET Hold will appear on the display. Keep E depressed until

SET Hold disappears and the magnetic declination settings start to flash.

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.

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.

5. Press C again to calibrate the second direction.

• - - - 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.
