Rotate the crown to adjust the time (hour and minute) setting.

 

• With the crown pulled out, rotate the crown more than once in the direction that you want to move

 

the hands. When you release the crown, the hands will start to move at high speed.

 

• Note that high-speed reverse movement is not supported.

 

• When adjusting the setting, check to make sure that the c Second Hand correctly indicates an a.m.

 

time or p.m. time.

1.In the Timekeeping Mode, loosen the crown and then pull it out.

•This will cause the c Second Hand to move to the city code of the currently selected Home City.

2.Hold down B for about one second.

•The c Second Hand will indicate whether the current time is a.m. (A)

or p.m. (P).

3.Press B twice.

•The b Day Indicator will move slightly to indicate the date setting mode.

4.Rotate the crown to adjust the date setting.

5.After making sure the b Day Indicator is not moving, press B. This will enter the month setting mode.

•The c Second Hand will move to the currently selected month.

6.Rotate the crown to adjust the month setting.

the hands. When you release the crown, the hands will start to move at high speed.

• Note that high-speed reverse movement is not supported.

• When adjusting the setting, check to make sure that the c Second Hand correctly indicates an a.m.

time or p.m. time.

• If you want to change the date setting at this time, press B and perform the procedure starting from

step 3 under “To change the current date setting manually” (page E-33).

7. After the setting is the way you want, push the crown back in and lock it.

• This causes timekeeping to resume with the c Second Hand starting from 12 o’clock.

7.Press B. This will enter the year setting mode.

•The z Hour Hand will move to the number that represents the tens digit value of the year and the x Minute Hand will move to the number that represents the ones digit value. The c Second Hand will move to 12 o’clock and stop there.

8.Rotate the crown to adjust the year setting.

The tens digit value setting changes automatically in accordance with the ones digit value setting.

•If you want to change the time setting at this time, press B and then perform the procedure starting from step 4 under “To change the current time setting manually” (page E-31).

9.After the setting is the way you want, push the crown back in and lock it.

Note

•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 3.

Taking Direction Readings

The Digital Compass Mode uses a direction sensor to take direction readings. After a direction reading, the c Second Hand points towards magnetic north.

Hand Indicators

c Second Hand: Points to magnetic north.

v Mode Hand: Points to COMP.

Note

The z Hour Hand and x Minute Hand are stopped during a digital

30

compass reading.

To take a direction reading

1. Make sure the watch is in the Timekeeping Mode.

• For information about changing modes, see “Selecting a Mode” (page E-24).

E-35

2.While keeping the watch horizontal, press C.

• This will enter the Digital Compass Mode, which is indicated by the

 

v Mode Hand moving to COMP.

 

• The c Second Hand will first move to 12 o’clock. Next it will move to

 

indicate magnetic north.

 

• For information about magnetic north, see “Compass Precautions”

30

(page E-41).

• The c Second Hand will continue to move for about 20 seconds after you start the digital compass operation as it adjusts its magnetic north reading. After that, the hand will stop at the final reading.

• To update a reading, press C again.

3. Press B to return to the Timekeeping Mode.

Calibrating the Bearing Sensor Reading

You should calibrate the bearing sensor reading whenever you feel that the direction readings being produced by the watch are off. You can use either of two sensor reading calibration methods: bidirectional calibration or northerly calibration.

•Bidirectional Calibration and Northerly Calibration

Bidirectional calibration and northerly calibration calibrate the accuracy of the bearing sensor. 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-36

3. Rotate the watch 180 degrees.

4. Press C to start calibration of Point 2.

• After about seven seconds, the c Second Hand will move to Y (Yes) if Point 2 calibration was successful or to N (No) if it was not successful.

• If the c Second Hand is pointing at N (unsuccessful), press C to

30

return to Point 1 calibration.

 

5.After calibration is complete, push the crown back in and then lock it.

•This will start a magnetic north reading operation.

•Press B to return to the Timekeeping Mode.

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.

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.

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, loosen the crown and then pull it out.

•The c Second Hand and x Minute Hand will move to 12 o’clock, and the z Hour Hand will move to 6 o’clock.

2. Press C to start calibration of Point 1.

• After about seven seconds, the c Second Hand will move to Y

30

(Yes) if Point 1 calibration was successful or to N (No) if it was not

successful.

 

 

• If the c Second Hand is pointing at N (unsuccessful), press C to

 

perform Point 1 calibration again.

 

• If the c Second Hand is pointing at Y (successful), it will move to

 

6 o’clock after about two seconds.

E-37

1.In the Digital Compass Mode, loosen the crown and then pull it out.

•The c Second Hand and x Minute Hand will move to 12 o’clock, and the z Hour Hand will move to 6 o’clock.

2. Press B. The z Hour Hand will move to 12 o’clock.

 

3. Place the watch on a level surface, and position it so that its 12 o’clock

30

position points north (as measured with another compass).

4. Press C to start calibration.

• After about seven seconds, the c Second Hand will move to Y (Yes) if calibration was successful or to N (No) if it was not successful.

• If the c Second Hand is pointing at N (unsuccessful), press C to perform calibration again.

5. After calibration is complete, push the crown back in and then lock it.

• This will start a magnetic north reading operation.

• Press B to return to the Timekeeping Mode.
