GENERAL GUIDE
• Press C to change from mode to mode.
• Pressing L in any mode illuminates the display for about 2 seconds.
• If you do not perform any operation for a few minutes while a setting screen (with flashing digits) is on the display, the watch automatically exits the setting screen.
• When making settings, note that you can scroll only forward, you cannot scroll back. This means that if you go past the setting you want, you must scroll through all of the available
settings again until the one you want reappears.
TIMEKEEPING MODE
• Press D to toggle between 12-hour and 24-hour time-
keeping.
• When the 12-hour format is selected, the indicator P
appears on the display for times from noon to 11:59 p.m.
to indicate “p.m.” There is no indicator for “a.m.” times.
• The indicator P does not appear when you are using
24-hour timekeeping.
• The display contents of the watch will not change if you
switch between 12-hour and 24-hour timekeeping while
the current time is between 1:00 a.m. and 11:59 a.m.

• The watch’s built-in full automatic calendar automatically makes allowances for
different month lengths and leap years. Once you set the date, there should be no
reason to change it except after the replacement of the watch’s battery.
∗
Daylight Saving Time (DST), which is also sometimes called “summer time” ad-
vances the time for one hour, as is the custom in some areas during the summer.
Remember that not all countries or even local areas use Daylight Saving Time.
To zero-reset the minutes and seconds (EASY ADJUST)
1.A few seconds before the arrival of the time on which you want to zero-reset the
minutes and seconds, hold down button B.
2.While still holding down button B, press button D when the time on which you
want to zero-reset the minutes and seconds arrives.
• The watch beeps to let you know that the minutes and seconds were reset to 00:00.
3.Release buttons B and D.
• If you press B and D while the minutes count is in the range of 30 to 59, they are
reset to 00 and 1 is added to the hour. If the minutes count is in the range of 00 to
29, the hour count is unchanged.
• Though the beep may sound slightly after the point you press both buttons, the
zero-reset setting should be correct.

Setting the Time and Date
There are two different ways to set the time and date. The procedure you should use
depends on whether you want to make major changes or minor changes to the cur-
rent setting.
ABOUT THE BACKLIGHT
• Press L to illuminate the display for about 2 seconds.
• The backlight of this watch employs an electro-luminescent (EL) light, which loses
its illuminating power after very long term use.
• Frequent use of the backlight shortens the battery life.
• The watch emits an audible sound whenever the display is illuminated. This does
not indicate malfunction of the watch.
• The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
• The backlight automatically turns off whenever an alarm sounds.
STOPWATCH MODE
About Lap times and Split times
Lap Times
A lap time is the amount of time it takes for you to get from one point to
another during a race. When running on a track, for example, you can time
how long it takes you to complete each lap.
Split Times
A split time is the time from the start of a race until the point that the split is
measured. For example, you could measure split times to determine how
long it takes for you to get from the starting line to the 5-kilometer mark, the
10-kilometer mark, etc.
The Stopwatch Mode lets you measure elapsed time, lap
times, and split times. The range of stopwatch is 23 hours,
59 minutes, 59 seconds. The first hour of a stopwatch
operation is measured in units of 1/100 second. After that,
elapsed time is measured in units of one second. You
can use the EL backlight by pressing L at any time while
the stopwatch is operating.

• In the Stopwatch Mode, the upper part of the display shows lap times, while the
lower part shows split times. When recalling times in the Recall Mode, you can
display either lap times or split times in the upper part of the display. The lower part
of the display shows the corresponding lap time or split time number. Note that the
lap/split time count value appears on the display in the Recall Mode only. It is not
displayed in the Stopwatch Mode.
To measure elapsed time
1.Press D to start the stopwatch.
2.Press D to stop the stopwatch.
• You can resume the elapsed time measurement operation by pressing D again.
• You can stop the elapsed time measurement operation by pressing D again.
3.While the elapsed time is stopped on the display, press B to clear the stopwatch
to all zeros.
When you want to do this:
Make major changes to the time and
date setting (before using the watch
for the first time, after having the bat-
tery replaced, etc.)
Make minor adjustments (within about
30 minutes of the current setting) to
the time setting
Use this procedure:
“To make major time and date settings”
“To zero-reset the minutes and sec-
onds (EASY ADJUST)”
