Taking Direction Readings

The Compass Mode uses the watch’s direction sensor to detect magnetic north. The second hand will indicate magnetic north and the digital display shows one of 16 directions and an angle value.

5.Press E to exit the setting screen.

•The hands of the watch will move to the time you set. Do not perform any operation on the watch while the hands are moving.

Note

•For information about selecting a Home City and configuring the DST setting, see “Configuring Home City Settings” (page E-20).

•Changing the time on the digital display will cause the time indicated by the hands to change accordingly. If the displayed time and the time indicated by the hands do not match, it could mean that the hand home positions are off. Adjust the hand home positions as required (page E-76).

•While 12-hour format is selected, 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-11).

To take a direction reading

1.Check to make sure the watch is in the Timekeeping Mode or one of the sensor modes.

•The sensor modes are the 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 the direction reading operation, which is indicated by COMP appearing on the digital display.

•When you press C, the second hand will first point in the direction of the C (COMP) button. This indicates the Compass Mode. After that the second hand will point in the direction of magnetic north.

•For information about direction reading results, see “Interpreting Direction Reading Results” (page E-26).

5.After you are finished taking direction readings, press D to return to the Timekeeping Mode.

Interpreting Direction Reading Results

•When you press C, COMP appears on the digital display to indicate that direction reading has started.

•After about two seconds, the second hand moves to point to magnetic north. The digital display shows either the angle between magnetic north and the 12 o’clock position of the watch, or one of 16 literal direction indicators.

•The watch updates the direction reading about once every second for about 20 seconds, and then stops. The digital display shows - - - and the second hand moves to COMP (located below the C

button) to indicate that direction readings are complete. If your want to continue taking direction readings, press C again.

•Pressing E at this time switches the digital display between the angle value and a one-, two-, or three-character literal direction indicators.

•The Auto Light switch is disabled during the 20 seconds that direction readings are being taken.

•The following table shows the meanings of the abbreviations used for the literal direction indicators that appear on the digital 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.

•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.

•If the second hand is indicating 12 o’clock (north), the digital display will show an upwards pointing white on black arrow.

•The small scale in the center of the watch face is a direction scale (page E-25). You can use the direction scale to get an idea of how many degrees the 12 o’clock position of the watch is (clockwise) from the northerly indication of the second hand. The direction scale is marked in 10-degree increments. Some watch models may not have a direction scale.

•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.

•For precautions that should be observed when using the Compass Mode, see “Compass Precautions” (page E-34).

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°.

E-27

•To return the magnetic declination to its initial factory default setting, press A and C at the same time. This will cause OFF to appear on the digital display. After about one second, the magnetic declination will change to 0 degrees.

•The illustration on page E-28 shows declination angle direction value and the angle value you should select when a map shows a magnetic declination of “West 1°”.

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

• This is the setting screen.

2. Press D to display the bidirectional calibration screen.

• At this time, the digital display will show -1-to indicate that the watch is ready to calibrate the first direction.

E-29

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 digital display while calibration is being performed. When calibration is successful, the digital display will show -2-. This means that the watch is ready for calibration of the second direction.

•Calibration takes about 13 seconds. Do not move the watch while calibration is being performed.

4.Rotate the watch 180 degrees.

5.Press C again to calibrate the second direction.

•- - - is shown on the digital display while calibration is being performed. When calibration is successful, the digital display will show OK and then change to the 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 Compass Mode, hold down E until each of the following steps occurs.

• Hold SET appears on the digital display. ➝ Magnetic declination settings flash.

• This is the setting screen.

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

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

4.Press C to start the calibration operation.

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

Using the Compass While Mountain Climbing or Hiking

This section provides two practical applications for using the watch’s built-in compass.

•Setting a map and finding your current location

Having an idea of your current location is important when mountain climbing or hiking. To do this, you need to “set the map”, which means to align the map so the directions indicated on it are aligned with the actual directions of your location. Basically what you are doing is aligning north on the map with north as indicated by the watch.

•Finding the bearing to an objective

To set a map and find your current location

1.With the watch on your wrist, position it so the face is horizontal.

2.While in the Timekeeping Mode or in any of the sensor modes, press C to take a compass reading.

•The reading result will appear on the digital display after about two seconds, and the second hand will point to north.
