3. While the seconds digits are selected (flashing), press D to reset the seconds to 00.
If you press D while the seconds count is in the range of 30 to 59, the seconds are
reset to 00 and 1 is added to the minutes. If the seconds count is in the range of 00
to 29, the minutes count is unchanged.
4. While any other digits (besides seconds) are selected (flashing), press D to increase
the number. While the 12/24-hour setting is selected, press D to switch between the
two formats.
· Holding down D changes the current selection at high speed.
· When the 12-hour format is selected, the 12H indicator appears on the display. With
the 12-hour format, the P (PM) indicator appears on the display to indicate "p.m."
times. There is no indicator for "a.m." times.
· Selecting the 24-hour format causes the 24H and the 24 indicators to appear on the
display.
5. After you set the time and date, press A to return to the Timekeeping Mode.
· The day of the week is automatically set in accordance with the date.
· The date can be set within the range of January 1, 1995 to December 31, 2039.
· If you do not operate any button for a few minutes while a selection is flashing, the
flashing stops and the watch goes back to the Timekeeping Mode automatically.
About the backlight
In any mode, press E to illuminate the display for about
three seconds. If the EL alarm is turned on, the backlight
flashes whenever a daily alarm or hourly time signal sounds.
Note
· For details on using the alarm function, see "ALARM
MODE".
· The backlight of the watch employs an electro-luminescent
(EL) light, which loses illuminating power after very long
use.
· The backlight remains lit for about three seconds from the point you press E , even if
it already lit when you press E . If you keep E depressed for one or two minutes, the
backlight will automatically turn off.
· The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
· The backlight automatically stops illuminating whenever an alarm sounds.
· The watch will emit an audible sound whenever the display is illuminated. This is caused
by a transistor that vibrates when the EL panel lights up. It does not indicate malfunction
of the watch.
To turn the EL alarm on and off
In the Timekeeping Mode, hold down D for one or two seconds to turn the EL alarm on
and off.
· An EL alarm on indicator (
) appears on the display to indicate that the EL alarm is
turned on. The indicator disappears when you turn the EL alarm off.
· When an alarm is reached while the EL alarm is turned on, the flashing of the backlight
and the timing of the alarm tones may not be exactly matched. This is normal and does
not indicate malfunction.

CONTACT CODE MODE
The Contact Code Mode lets you store up to 20* sets of
contact data (such as telephone numbers). Stored data is
sorted automatically into alphabetic sequence based on the
text area text.
* The Contact Code Mode shares memory with the
Identification (ID) Mode. This means that the maximum
number of Contact Code Mode entries you can store is
reduced by one each time you store Identification Mode.
To check remaining memory
In the Contact Code Mode, hold down B and D to display
how much memory remains for input of data. The value that
appears shows how many more data items (Contact Code
Mode and ID Mode) you can input.
· This watch has three built-in ID Mode titles, which are programmed in memory when
you first purchase the watch and which are automatically set whenever the watch's
battery is replaced. Because of this, the remaining memory display shows a value of
17 (20 3) whenever it is performed immediately after you purchase the watch or
have the battery changed.
To input new Contact Code data
1. In the Contact Code Mode, press B or D until the new
data screen appears.

that memory is full. To store more data, you will first have
to delete some of the data stored in memory.

· Use the Vital Statistics Mode to store your own personal data (name, blood type, date
of birth). Once you input your personal data, take care that the watch is not borrowed
by another person. Otherwise, emergency medical personnel may assume that your

IDENTIFICATION (ID) MODE
With the Identification (ID) Mode, you can input up to 20*
sets of data, each of which contains a title (such as passport,
credit card, etc.) and a number. Data is automatically sorted
into the alphabetic sequence of the titles.
* The ID Mode shares memory with the Contact Code Mode.
This means that the maximum number of ID Mode entries
you can store is reduced by one each time you store
Contact Code Mode.
Important!
The ID Mode is useful for storing important data like passport numbers, license numbers,
credit card numbers, etc. Note, however, that storing such important data in the watch's
memory runs the risk of it being misused should you lend the watch to someone, or should
the watch become lost or stolen. Because of this, the manufacturer strongly recommends
that you store such important information in coded form that cannot be understood by
others.
Note that CASIO COMPUTER CO., LTD. shall not be held liable to you or any third party
for any losses or damages suffered through the misuse of data stored in the memory of
this watch.

characters long.
