Using the Watch for Official Timing of a Sport Event
After you set a game or event time, the watch will perform an alert operation (beeper or vibration) when the time in the lower display reaches that time. If the event is interrupted for some reason, you can press B to pause and restart timing in the upper display. The lower display shows the total elapsed time since the start of the timing operation. You can calculate the total amount of time that play was interrupted (lost time or injury time) by subtracting the upper display time from the lower display time.
Stop*
The stopwatch lets you measure elapsed time. The upper display and lower display can be used for official timing of an event or game.
You can configure the watch for beeper alert or vibration alert. For details about vibration alert, see “Vibration Alert”.
The measurement range of the upper display is 59 minutes 59 seconds.
The measurement range of the lower display is 99 minutes 59 seconds.
The stopwatch continues to run, restarting from zero after it reaches its limit, until you stop it.
The stopwatch measurement operation continues even if you exit the Stopwatch Mode.
All of the operations in this section are performed in the Stopwatch Mode, which you enter by pressing C .

Note that the DST/Standard Time setting affects only the currently displayed city code. Other city codes are not affected.
About the Auto Light Switch
While the auto light switch is enabled, illumination turns on whenever you position your wrist as described below in any mode.
Moving the watch to a position that is parallel to the ground and then tilting it towards you at more than 40 degrees causes illumination to turn on.
Wear the watch on the outside of your wrist.
Parallel to ground More than 40
Warning!
Always make sure you are in a safe place whenever you are reading 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 startle 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.
To turn the auto light switch on and off
In the Timekeeping Mode, hold down B for about three seconds to toggle the auto light switch on (A.EL displayed) or off (A.EL not displayed).
The auto light switch indicator is on the display in all modes while the auto light switch is turned on.
In order to protect against running down the battery, the auto light switch turns off automatically approximately six hours after you turn it on.

Illumination
This watch has an EL (electro-luminescent) panel that causes the entire display to glow for easy reading in the dark. The watch’s auto light switch turns on illumination automatically when you angle the watch towards your face for reading.
The auto light switch must be turned on (indicated by the auto light switch indicator) for it to operate.
See “Illumination Precautions” for more important information.
Auto light switch indicator
To illuminate the display manually
In any mode, press L to turn on illumination for about one second.
The above operation turns on illumination regardless of the current auto light switch setting.
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.
Vibration Alert
When Vibration Alert is turned on, the watch vibrates instead of sounding a beeper. This lets you use the watch without disturbing others with beeping sounds.
Vibration Alert can be used to replace alarm sounds.
For information about selecting the alert type, see “To switch between vibration alert
and beeper alert” below.
Watches with a metal band may produce a noise when a vibration operation is performed. This is due to vibration of the metal band, and does not indicate malfunction of the watch.

Scrolling
The B and D buttons are used in various modes and setting screens to scroll through data on the display. In most cases, holding down these buttons during a scroll operation scrolls at high speed. This is true except when the interval timer number is flashing on the Interval Timer Mode screen.
Auto Return Features
If you leave the watch in the Alarm Mode for two or three minutes without performing
any operation, it changes to the Timekeeping Mode automatically.
If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch exits the setting screen automatically.

Illumination Precautions
The electro-luminescent panel that provides illumination loses power after very long use.
Illumination 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.
Illumination turns off automatically whenever an alert operation (beeper or vibration) is performed.
Frequent use of illumination runs down the battery.
Auto light switch precautions
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.
Static electricity or magnetic force can interfere with proper operation of the auto light switch. If illumination does not turn on, try moving the watch back to the starting position (parallel with the ground) and then tilt it back towards 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, illumination may not turn on until about one second after you turn the face of the watch towards you. This does not necessarily indicate malfunction of the auto light switch.
You may notice a very faint clicking sound coming from the watch when it is shaken back and forth. This sound is caused by mechanical operation of the auto light switch, and does not indicate a problem with the watch.
Illumination may not turn on 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.
Illumination turns off in about one second, even if you keep the watch pointed towards your face.

6-2. ACCURACY CHECKING
Check the accuracy of the module with the quartz timer after switching the module to “ACCURACY CHECKING MODE”.
The operations are shown below:
A) SWITCHING TO “ACCURACY CHECKING MODE”
While pressing the D button, press A and C buttons at the normal timekeeping mode. Then all the segments are displayed and the LCD drive signals are changed to the static drive signal of “32 Hz” so that you can check the accuracy with the quartz timer.
B) CANCELLATION OF THE “ACCURACY CHECKING MODE”
Press any button, except for D button. Then the display is returned to its original state.
NOTE: The “ACCURACY CHECKING MODE” will
automatically return to the regular mode in 1 ~ 2 hour(s) without any operation.
