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 0.
• Note that the Hijri offset also returns to 0 whenever you change the watch’s Gregorian date setting or the latitude and/or longitude settings.
• Changing the watch’s Gregorian date setting can cause an error in the displayed Hijri date 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 watch 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.

Viewing Prayer Names and Prayer Times

This watch is designed to display prayer name and prayer start times. The Today’s Salat Time Screen shows prayer times and elapsed prayer time. A Prayer Time Alarm (which can be enabled or disabled) 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 code, 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 configured correctly.

To display today’s prayer times

1. In the Timekeeping Mode, press D.
   • This displays the Today’s Salat Time Screen.

2. Press D to display the next prayer name and prayer start time.• If three to four seconds elapse without any operation being performed, the watch will return to the Timekeeping screen (Gregorian) (page E-15).
   • Pressing A returns to the Timekeeping screen (Hijri/ Moon age) (page E-15).
   • If the time of the next prayer arrives while you are viewing today’s prayer times, the watch will perform a prayer alarm alert operation (page E-32) and return to the Timekeeping screen (Gregorian).

To enable or disable a prayer alarm

1. In the Timekeeping Mode, hold down A for about five seconds until the ON or OFF starts to flash. Release A as soon as the flashing starts.
   • This displays the prayer alarm enabled/disabled setting screen.
   • This indicator shows the current alarm enabled/ disabled setting.

2. Press C as many times as necessary to display the name of the prayer whose prayer alarm setting enable/ disable you want to change.
   • If the prayer alarm of the displayed prayer is enabled, SALAT will be displayed below its prayer name. No indicator is shown if the displayed alarm is disabled.
   • SALAT will not appear if the Hijri/Moon age Timekeeping screen or the Gregorian/Moon age Timekeeping screen (page E-15) is displayed.

3. Press D to toggle the display alarm between enabled and disabled.

4. After the setting is the way you want, press A twice to return to the Timekeeping Mode.

To stop a sounding prayer alarm
Press any button.
To switch a prayer alarm between audible and silent
In the Timekeeping Mode, hold down D for about two seconds.

• This toggles prayer alarms between audible and silent ( ). If silent is set for the prayer alarm, will be displayed next to SALAT below the prayer name.
  Nothing is displayed next to SALAT below the prayer name if audible is set for the prayer alarm.

• All prayer alarms are silent while silent is set for the prayer alarm. In this case the prayer name and time will flash on the display when a prayer time is reached.

• The prayer alarm enabled/disabled setting is not changed.

• Button operation tones will sound, even if silent is selected for the prayer alarm. To disable button operation tones, see “To enable or disable the button operation tone” (page E-58).

Displaying Elapsed Prayer Time

The Timekeeping screen (Gregorian) shows elapsed time up to 30 minutes following a prayer time, only for prayers whose prayer alarm time is enabled.

• If 30 minutes elapse, the watch will automatically display the next prayer name and prayer start time. 30 minutes after the current day’s final prayer, the Timekeeping screen (Gregorian/Moon age) will appear and remain displayed until midnight.
• While the prayer elapsed time is displayed, you can press D to display the next prayer name and prayer start time. While the current day’s final prayer time is displayed, you can press D to display the Gregorian/Moon age Timekeeping screen (page E-15), which will remain displayed until midnight.
• Pressing A will display the Hijri/Moon age Timekeeping screen (page E-15) for aboutthree or four seconds. After that, the elapsed prayer time will re-appear.

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 five 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.
