Congratulations upon your selection of this CASIO watch.

About This Manual

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

either as dark ﬁ gures on a light background, or light ﬁ gures on a dark background. All sample displays 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.

•

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.

• 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.

•

To ensure correct direction readings by this watch, be sure to perform bidirectional calibration before using it. The watch may produce incorrect direction readings if you do not perform bidirectional calibration. For more information, see “To perform bidirectional calibration” (page E-24).

•

Keep the watch away from audio speakers, magnetic necklace, cell phone, and other devices that generate strong magnetism. Exposure to strong magnetism can magnetize the watch and cause incorrect direction readings. If incorrect readings continue even after you perform bidirectional calibration, it could mean that your watch has been magnetized. If this happens, contact your original retailer or an authorized CASIO Service Center.

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-12) to conﬁ gure your Home City and daylight saving time settings.

Important!

Proper Hijri calendar, Prayer Time Mode, and Moon Age Mode data depend on correct Home City, time, and date settings in the Timekeeping Mode. Make sure you conﬁ gure these settings correctly.

2. Conﬁ gure latitude and longitude settings for your current location.

See “To select a Home City by conﬁ guring latitude and longitude settings” (page E-14).

3. Set the current time.

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

Calibrating the Bearing Sensor Reading

You should calibrate the bearing sensor whenever you feel that the direction readings being produced by the watch are off. Bearing sensor calibration is performed using bidirectional calibration. After calibration the sensor, you can also manually perform 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!

• To ensure correct direction readings by this watch, be sure to perform bidirectional calibration

before using it. The watch may produce incorrect direction readings if you do not perform bidirectional calibration.

• Keep the watch away from audio speakers, magnetic necklace, cell phone, and other devices

that generate strong magnetism. Exposure to strong magnetism can magnetize the watch and cause incorrect direction readings. If incorrect readings continue even after you perform bidirectional calibration, it could mean that your watch has been magnetized. If this happens, contact your original retailer or an authorized CASIO Service Center.

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.

• If ERR appears on the di gital display, press B again to restar t calibratio n.

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°.

• The illustration, for example, shows the valu e you should in put and the dire ction setti ng you

should sel ect when the ma p shows a magne tic declination of 7° West.

4. When the setting is the way you want, press A to exit the setting screen.

Digital Compass Precautions

This watch features a built-in magnetic bearing sensor that detects terrestrial magnetism. This means that north indicated by this watch is magnetic north, which is somewhat different from true polar north. The magnetic north pole is located in northern Canada, while the magnetic south pole is in southern Australia. Note that the difference between magnetic north and true north as measured with all magnetic compasses tends to be greater as one gets closer to either of the magnetic poles. You should also remember that some maps indicate true north (instead of magnetic north), and so you should make allowances when using such maps with this watch.

Location

• Taking a direction reading when you are near a source of strong magnetism can cause large

errors in readings. Because of this, you should avoid taking direction readings while in the vicinity of the following types of objects: permanent magnets (magnetic necklaces, etc.), concentrations of metal (metal doors, lockers, etc.), high tension wires, aerial wires, household appliances (TVs, personal computers, washing machines, freezers, etc.).

• Accurate direction readings are impossible while in a train, boat, air plane, etc.

• Accurate readings are also impossible indoors, especially inside ferroconcrete structures. This

is because the metal framework of such structures picks up magnetism from appliances, etc.

Storage

• The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Because

of this, you should store the watch away from magnets or any other sources of strong magnetism, including: permanent magnets (magnetic necklaces, etc.) and household appliances (TVs, personal computers, washing machines, freezers, etc.).

• Whenever you suspect that the watch may have become magnetized, perform the procedure

under “To perform bidirectional calibration” (page E-24).

Viewing Prayer Names and Prayer Times

This watch is designed so its second hand points to prayer names on the face, and displays prayer times. The Today’s Salat Time Screen shows prayer times and elapsed prayer time. The SALAT time search mode can be used to view the prayer times for a speciﬁ c date. A Prayer Time Alarm (which can be switched on and off) sounds for 10 seconds when each prayer time arrives. Press any button to stop the alarm after it starts to sound.

About prayer times

Prayer times are calculated automatically in accordance with the time, date, city data, and prayer time calculation method you set in the Timekeeping Mode. This, of course, means that you should always make sure that your Timekeeping Mode settings are conﬁ gured correctly.

About prayer time calculation methods

Methods that are used to determine prayer times (especially Fajr, Asr, and Isha) differ somewhat between countries and regions. This watch comes with a total of ﬁ ve built-in prayer time calculation methods that conform with various geographical areas around the world. In addition, you can also set your own calculation method for calculation of Fajr, Asr, and Isha.

While the Today’s Salat Time Screen is displayed, the digital display will show the time elapsed for up to 30 minutes after the start of the prayer. The second hand will remain pointing to the name of the ongoing prayer. Elapsed prayer time is shown only while Today’s Salat Time Screen is displayed.

Display Units

You can select either Celsius (°C) or Fahrenheit (°F) for the displayed temperature value. See “To specify temperature unit” (page E-40) for more information.

Thermometer Precautions

• Temperature measurements are affected by your body temperature (while you are wearing the

watch), direct sunlight, and moisture. To achieve a more accurate temperature measurement, remove the watch from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding temperature.

• When taking temperature readings, it is best to remove the watch from your wrist in order to
