•Note that the above steps work only when the currently displayed screen is
initialized (reset). The Countdown Timer is initialized when its start time is displayed,
while the Stopwatch is initialized when it shows all zeros.
•See “STOPWATCH”for information about using the Stopwatch.
Countdown Timer Operation
The countdown timer counts down the displayed time in one-second increments,
starting from a countdown start time set by you. Aprogress beeper beeps each
minute, and each second for the last 10 seconds of the countdown. The operation of
the beeper is very useful for match race and ocean race timing.
•Before using the Countdown Timer, you should set the countdown start time and
select either match race timing or ocean race timing as the timing method.
Match Race Timing
When you set up the countdown timer for match race timing, the countdown
automatically restarts from the countdown start whenever zero is reached. This type
of timing is best for match races, with start at regular intervals (every five minutes, for
example).
Ocean Race Timing
With ocean race timing, the stopwatch starts timing automatically as soon as the
countdown reaches zero. This type of timing is best for ocean racing, which is
conducted based on accumulated time following the start.
To set the countdown time
1.In the Countdown Timer Mode, hold down Auntil the
hour digit of the countdown time starts to flash, which
indicates the setting screen.
2.Press Cto move the flashing between the hours and
minutes.
3.While a setting is flashing, press Dto increase it.
•To set the countdown start time to 24 hours, set
0:00.
4.Press Ato exit the setting screen.
To select the timing method
1.In the Countdown Timer Mode, hold down Auntil the
hour digit of the countdown time starts to flash, which
indicates the setting screen.
2.Press Bto toggle the timing method between match
race timing ( indicator) and ocean race timing
(indicator).
3.Press Ato exit the setting screen.
To use the countdown timer
Press Bwhile in the Countdown Timer Mode to start the countdown timer.
•Press Bwhile a countdown operation is in progress to pause it. Press Bagain to
resume the countdown.
•To completely stop a countdown operation, first pause it (by pressing B), and then
press D. This returns the countdown time to its starting value.
Note
•Match race timing continues until you stop it. Note that the progress beeper can
down the battery power after long periods, so you should stop the timing operation
when you are not using the countdown timer.
•In the case of ocean race timing, stopwatch operation that starts at the end of the
countdown is the same as that for normal Stopwatch Mode timing. See “To measure
times with the stopwatch”for more information. Note that initializing the stopwatch
(clearing it to all zeros) after an ocean race timing operation also initializes the
countdown timer by returning it to its starting value.

BACKLIGHT
The backlight uses an EL (electro-luminescent) panel that
causes the entire display to glow for easy reading in the
dark. The watch’s auto light switch automatically turns on
the backlight when you angle the watch towards your
face.
•The auto light switch must be turned on (indicated by
the auto light switch on indicator) for it to operate.
•See “Backlight Precautions”for other important
information about using the backlight.
To turn on the backlight manually
In any mode, press Lto illuminate the display for about two seconds.
•The above operation turns on the backlight regardless of the current auto light
switch setting.
About the Auto Light Switch
Turning on the auto light switch causes the backlight to turn on for about two seconds,
whenever you position your wrist as described below in any mode.
•Be sure to wear the watch on the outside of your left wrist while using the auto light
switch.
Moving the watch to a position that is parallel to the ground and then tilting it
towards you more than 40 degrees causes the backlight to turn on.
Parallel to ground More than 40 °
Warning!
•Always make sure you are in a safe place whenever you are reading the
display of the watch using the auto light switch. Be especially careful when
running or engaged in any other activity that can result in accident or injury.
Also take care that sudden illumination by the auto light switch does not
surprise or distract others around you.
•When you are wearing the watch, make sure that its auto light switch 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
personal injury.

In the Timekeeping Mode, hold down Dfor about two seconds to toggle the auto light
switch on ( displayed) or off ( not displayed).
•The auto light switch on indicator ( ) is on the display in all modes while the auto

REFERENCE
This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Auto Return Features
If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch automatically saves anything you have
input up to that point and exits the setting screen.
Data and Setting Scrolling
The Dbutton is used to scroll through setting screen data on the display. In most
cases, holding down this button during a scroll operation scrolls through the data at
high speed.
Backlight Precautions
•The electro-luminescent panel that provides illumination loses power after very long
use.
•The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
•The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
•The backlight automatically turns off whenever an alarm sounds.
•The backlight remains lit for about two seconds from the point you press the button,
even if it is already lit when you press the button. If you keep the button depressed
for two seconds or more, the backlight automatically turns off.
•Frequent use of the backlight shortens the battery life.
Auto light switch precautions
•In order to protect against running down the battery, the auto light switch
automatically turns off approximately six hours after you turn it on.
•Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light
switch to operate when it is not needed, which shortens battery life. If you want to
wear the watch on the inside of your wrist, turn off the auto light switch feature.
•The backlight may not light if the face of the watch is
more than 15 degrees above or below parallel. Make
sure that the back of your hand is parallel to the ground.
•The backlight turns off in about two seconds, even if you
keep the watch pointed towards your face.
•Static electricity or magnetic force can interfere with proper operation of the auto
light switch. If the backlight does not light, 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 after
you turn the face of the watch towards you. This does not necessarily indicate
malfunction of the backlight.
