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.
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 seconds”
To make major time and date settings
1. While in the Timekeeping Mode, hold down A until the seconds digits flash on the
display, indicating the setting screen.
2. Press C to move the flashing in the sequence shown below.

3. While the seconds setting is selected (flashing), press D to reset it to 00. If you
press D while the seconds setting is in the range of 30 to 59, the seconds are
reset to 00 and 1 is added to the minutes. If the seconds setting is in the range of
00 to 29, the minutes count is unchanged.
• While the DST

setting is selected (DST on indicator is flashing), press D to toggle
it on (on) and off (OFF).
4. While any other setting is selected (flashing), press D to increase it. Holding down
D changes the setting at high speed.
5. After you make the settings you want, press A to exit the setting screen.
• The day of the week is automatically set in accordance with the date.
• The date can be set within the range of January 1, 2000 to December 31, 2039.
• The watch’s built-in full automatic calendar automatically makes allowances for dif-
ferent 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 .
• Though the beep may sound slightly after the point you press both buttons, the
zero-reset setting should be correct.
ABOUT THE BACKLIGHT
About the Auto Light Switch Function
When the auto light switch function is turned on, the backlight automatically turns on
for two seconds under the conditions described below. Avoid wearing the watch on
the inside of your wrist. Doing so causes the auto light switch to operate when not
needed, which shortens battery life.
Moving the watch to a position that is parallel to the ground and then tilting it
towards you approximately 40 degrees causes the backlight to illuminate.
• The backlight may not illuminate if the face of the watch is more than 15 degrees off
parallel to the left or right. Make sure that the back of your hand is parallel to the
ground.
Parallel to ground More than 15 degrees More than 15 degrees
too high too low
• Static electricity or magnetic force can interfere with proper operation of the auto
light switch function. If the backlight does not illuminate, try moving the watch back
to the starting position (parallel with the ground) and then tilt it back toward you
again. If this does not work, drop your arm all the way down so it hangs at your side,
and then bring it back up again.
• Under certain conditions the backlight may not light until about one second or less
after turn the face of the watch towards you. This does not necessarily indicate
malfunction of the backlight.
To switch the auto light switch function on and off
In the Timekeeping Mode, hold down D for one or two seconds to turn the auto light
switch function on and off.
• Note that pressing D also switches the display between 12-hour and 24-hour time-
keeping.
Auto light switch indicator
ON OFF
• The auto light switch indicator is shown on the display in all modes while the auto
light switch function is on.
• In order to protect against running down the battery, the auto light switch function is
automatically turned off approximately five hours after you turn it on. Repeat the
above procedure to turn the auto light switch function back on if you want.
• Pressing L at any mode illuminates the display, regardless of the auto light switch’s
on/off setting.
Caution
• 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 is
because the EL light vibrates slightly when lit. It does not indicate malfunction of
the watch.
Warning!
• Never try to read your watch when mountain climbing or hiking in areas that
are dark or in areas with poor footing. Doing so is dangerous and can result
in serious personal injury.
• Never try to read your watch when running where there is the danger of acci-
dents, especially in locations where there might be vehicular or pedestrian
traffic. Doing so is dangerous and can result in serious personal injury.
• Never try to read your watch when riding on a bicycle or when operating a
motorcycle or any other motor vehicle. Doing so is dangerous and can result
in a traffic accident and serious personal injury.
• When you are wearing the watch, make sure that its auto light switch function
is turned off before riding on a bicycle or operating a motorcycle or any other
motor vehicle. Sudden and unintended operation of the auto light switch can
create a distraction, which can result in a traffic accident and serious per-
sonal injury.
