• Whenever you change to another city code from a city code whose pre-programmed
data has been changed, the changed data is automatically reset to their initial
(unchanged) settings. You have to make the changes again if you wish to return to
the original city code.
• New settings that you make (using "_ _ _" as the city code) are stored in memory
until you change them. If you change from "_ _ _" to another city code, the settings
for "_ _ _" are retained.
2-2 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 seven
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.

• The date display (Hijra or Gregorian) you select here determines the format for the

the Hijra date format is used in the Prayer Time Mode as well. Note also that a Hijra
date indicator appears on the display while the Hijra date display is selected.
