Congratulations upon your selection of this CASIO watch.

Applications

This watch has built-in sensors that measure direction and temperature. Measurement results are indicated by the watch's hands and displays. These features make this watch useful when hiking, mountain climbing, or when engaging in other such outdoor activities.

• The measurement functions built into this watch are not intended for taking measurements that

require professional or industrial precision. Values produced by this watch should be considered as reasonable representations only.

•

When engaging in mountain climbing or other activities in which losing your way can create a dangerous or life-threatening situation, always use a second compass to conﬁ rm direction readings.

• Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage or loss

suffered by you or any third party arising through the use of this product or its malfunction.

About This Manual

• Depending on the model of your watch, display text appears either as

dark ﬁ gures on a light background, or light ﬁ gures on a dark background. All examples in this manual are shown using dark ﬁ gures on a light background.

• Button operations are indicated using the letters shown in the

illustration.

• Note that the product illustrations in this manual are intended for

reference only, and so the actual product may appear somewhat different than depicted by an illustration.

Warning!

Things to check before using the watch

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

Use the procedure under “To conﬁ gure Home City settings” (page E-13) to conﬁ gure your Home City and daylight saving time settings.

Important!

Proper World Time Mode data depends on correct Home City, time, and date settings in the Timekeeping Mode. Make sure you conﬁ gure these settings correctly.

2. Set the current time.

See “Conﬁ guring Current Time and Date Settings” (page E-15).

The watch is now ready for use.

Using the Digital Compass

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

• 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 pressingB). The digital compass operation resumes for its remaining duration after the operation that caused it to pause is ﬁ nished.

• 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.

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 C to perform a digital compass operation.

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

• COMP will appear in th e upper display to i ndicate that a di gital

compass o peration is i n progress.

• See “Dig ital Comp ass Reading s” (page E-21) for infor mation

about how di rection readi ngs are indicate d by the watch.

Note

• If there is an an gle value in the u pper display, it mea ns that the

bearing me mory rec ord (page E-2 6) is displayed. If t his happens , press E to exit the bea ring memo ry 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 D for at least two seconds.

Digital Compass Readings

• When you press C to start a digital compass operation,

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 ﬁ rst 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

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

West

• 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.

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 speciﬁ ed 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 ﬁ eld, for example, calibrate in an open ﬁ eld.
