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).

The watch is now ready for use.

Conﬁ guring Current Time and Date Settings

You can use the procedure below to adjust the current time and date settings if they are off. Changing the digital Home City data should cause the analog time setting to change accordingly. If the analog time does not indicate the digital time, check the home positions of the hands and make adjustments if necessary (page E-19). This watch displays Hijri calendar months and days. The watch normally calculates and displays Hijri calendar dates automatically. If necessary, you can correct the displayed data by ±3 days.

Note

• For information about selecting a Home City and conﬁ guring the DST setting, see “Conﬁ guring

Home City Settings” (page E-12).

• 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 battery replaced.

• Changing your Home City setting will cause all of the following settings to become initialized:

latitude and longitude (to the location of the Home City), the prayer calculation method (Fajr, Isha, Asr), and the Qibla declination (in accordance with the selected Home City). Note that these settings are not initialized when

Note

• The Hijri offset setting is temporary. At the end of each month, the watch automatically corrects

the Hijri date and returns the Hijri offset to

• Note that the Hijri offset also returns to

date setting or the latitude and/or longitude settings.

• Changing the watch’s Gregorian date setting can cause an error in the displayed Hijri until the

watch performs automatic Hijri date correction at the end of the month (on the 29th or 30th day of the month). If the Hijri date display is wrong, adjust it by changing the Hijri date offset.

Hijri Calendar Precautions

Hijri dates displayed by this calculator are the results of calculations. Actual Hijri dates may be determined by religious authorities based on observations of a New Moon following sundown. This can result in dates calculated by the watch being different from actual Hijri dates.
