PART 2 TIMEKEEPING MODE

This part of the manual tells you how to set the city data (to tell the watch where you
are), the prayer time calculation method,* and the current time and date. Note that the
settings you make in the Timekeeping Mode are used by the Digital Compass and
Prayer Time function. Make sure you make these settings correctly.
* There are number of different prayer time calculation methods in use, depending on

geographic region. This watch is pre-programmed to calculate prayer times in
accordance with the method you select. For details, see “2-2 About prayer time
calculation methods.”

• In the Timekeeping Mode, you can switch the date display between Hijra style and
Gregorian style. For details, see “2-4 About the Timekeeping Mode display.”

• In the Timekeeping Mode, hold down B to illuminate the display.

2-1 About city data...

With the city data, you tell the watch your current location so that it can calculate other data.
Be sure to c ha ng e the city data setting whenever you move from one city to ano th e r .
City data consist of time differential from Greenwich Mean Time (GMT), latitude,
longitude, and directional variation (variation between true north and magnetic north)
for the city where you are currently located. You can use either of the two following
methods to set city data.

• Standard Data Input

With this method, you simply specify one of 30 pre-programmed city codes, and all
other data (based on data for 1990) is input automatically. With this method, however,
you must remember to change the time differential from GMT whenever you switch
between summer time and standard time. A complete list of the available city codes

can be found at the end of this manual.

• Original Data Input
With this method, you make each of the settings by yourself. There are two methods
you can use to preset original data: editing pre-programmed city data or inputting new
data.
To edit pre-programmed city data, you select one of the pre-programmed city codes
and make changes in its data to suit your current location.
To input new data, you must make each setting one-by-one.

To set city data using city codes

1. Press ( A ) while in the Timekeeping Mode. At this time,

the currently set city code starts to flash on the display
because it is selected.

Graphic display area

2. While the city code is selected (flashing), press (D) or
(B) to scroll through the 3-letter city codes until the one
you want is displayed.

• See the City Code List at the end of this manual for a full

list of available city codes.

3. After you select your city code, press © to advance to
the GMT differential setting.

(+9 hours) adjust for the 1 -hour change for summer time), press

to increase the time differential or (B) to decrease it.

• If you do not want to change the GMT differential setting, skip this step and proceed
to step 5.

• Pressing (D) and (B) changes the time differential in 15-minute increments.

• The hours setting changes automatically whenever a change in the minutes settings
increases or decreases past 00.

• You can set the GMT differential within the range of -11 hours to +13 hours 45
minutes.

5. After you finish making your setting, press (A ) twice to return to the Timekeeping

Mode.

• After you change the setting in the above procedure, the watch needs a bit of time to
calculate certain information. During this calculation, the pattern in the graphic
display moves. Wait until this display stops moving before you try to set any further
data.

• If you do not operate any button for a few minutes while a selection is flashing, the
flashing stops and the watch automatically goes back to the Timekeeping Mode.

• After you change the GMT differential for summer time, the city code (which is
displayed with the city data when setting the prayer time calculation method) is
marked with a to indicate that its data has been changed.

To set original city data

When setting original city data, you can use the City Data List at the back of this
manual and the Directional Variation Map (included separately with this watch).

1. Press (A) while in the Timekeeping Mode. At this time,

the currently set city code starts to flash on the display
because it is selected.

2. While the city code is selected (flashing), press (B ) or (D)
to scroll through the 3-letter city codes until the one you
want is displayed.

• If you are going to use pre-programmed city data, you

should select a city code for a location that is close to the
one whose data you want to set.

• If you are going to input new data, select “_ _ _” as the

city code.

• Anytime you change pre-programmed city data, the city

code (which is displayed with the city data when setting
the prayer time calculation method) is marked with a “ # ”
to indicate that its data has been changed.

Note here that the prayer time calculation method (see “2-2 About prayer time
calculation methods") is also considered to be part of the pre-programmed data.
Because of this, ” is shown with the city code if the prayer time calculation method
has been changed, also.

• 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.

15.0° (User programmable)

• Numbers 1 through 7 are pre-programmed calculation methods, while 0 is reserved

for input of a user calculation method. These numbers are used to specify the
calculation method that you want.

• The degree values in the above table (such as: 18.0°) indicate the angle of sun below

the horizon. The values — 1 and — 2 have the following meanings.
FAJR - - 1 : 90 minutes before sunrise

— 2 : 120 minutes before sunrise

ASR — 1 : Shadow length equal that produced by objects

- - 2 : Shadow length double that produced by objects

ISHA - - 1 : 90 minutes after sunset

— 2 : 90 minutes after sunset, and 120 minutes after sunset during Ramadan

The — 1 or — 2 setting of No. 0 can be changed when making its angle o f sun

below the horizon settings.

• For the angle of sun below horizon values, one degree of angular differential is
equivalent to a time differential of approximately four minutes.

• At latitudes greater than 45° (north or south), this watch extrapolates Fajr and Isha
prayer times based on the proportion of night time, and predawn light/twilight at 45°
(north or south).

• This watch’s pre-programmed prayer calculation methods were carefully selected to
provide the widest possible applicability. Note, however, that there are still other
calculation methods and variations.

Important!

This watch uses a 30-day cycle to calculate the Hijra months. Because of this, the Hijra
date shown by this watch may differ from the actual date. When this happens, use
time/date setting procedure described above to change the date to its correct setting.
Also note that the watch uses midnight as the point for the change of date.

Important!

• The date display (Hijra or Gregorian) you select here determines the format for the
date that appears in other modes. If you select the Hijra date display, for example,
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.

• Whenever the Prayer Time Display is selected, the next sequential prayer time (Fajr,
Zohr, Asr, Mgrib, Isha) is indicated on the display.

• AM and PM is not indicated on the Prayer Time Display.

• The next prayer time indicated on the Prayer Time Display changes one minute after
the indicated prayer time is reached.

• The next prayer time is indicated for the current date only. Because of this, the Isha

prayer time remains on the display even after Isha is passed. The next prayer time

will change to Fajr after midnight.
