Illumination
This watch has two LEDs (light-emitting diode) that cause
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 for reading towards your face.
The auto light switch must be turned on (indicated by the •
auto light switch on indicator) for it to operate.
See “Illumination Precautions” for more important •
information.

To turn on illumination
In any mode (except when a setting screen is on the display), press B to turn on
illumination.
You can use the procedure above to select either 1.5 seconds or 3 seconds as the •
illumination duration. When you press B, the illumination will remain on for about
1.5 seconds or 3 seconds, depending on the current illumination duration setting.
To specify the illumination duration
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. •
In the Timekeeping Mode, hold down 1. A until the
seconds start to flash, which indicates the setting
screen.

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 (auto light switch on indicator displayed) or off (auto light switch on
indicator not displayed).
The auto light switch on 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.

indicator displayed).
Holding down • C to turn the button operation tone on or off also causes the watch’s
current mode to change.
The mute indicator is displayed in all modes when the button operation tone is •
turned off.
Auto Return Features
If you leave the watch in the Alarm Mode for two or three minutes without performing •
any operation, it automatically changes to the Timekeeping Mode.
If you leave a screen with flashing digits on the display for two or three minutes •
without performing any operation, the watch automatically exits the setting screen.

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.

The year can be set in the range of 2000 to 2099. •
The watch’s built-in full automatic calendar makes allowances for different month •
lengths and leap years. Once you set the date, there should be no reason to change
it except after you have the watch’s battery replaced.
World Time
The seconds count of the World Time is synchronized with the seconds count of the •
Timekeeping Mode.
All World Time Mode times are calculated from the current Home City Time in the •
Timekeeping Mode using UTC time offset values.
The UTC offset is a value that indicates the time difference between a reference •
point in Greenwich, England and the time zone where a city is located.
The letters “UTC” is the abbreviation for “Coordinated Universal Time”, which is the •
world-wide scientific standard of timekeeping. It is based upon carefully maintained
atomic (cesium) clocks that keep time accurately to within microseconds. Leap
seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s
rotation.

Illumination Precautions
Illumination loses power after very long use. •
Illumination may be hard to see when viewed under direct sunlight. •
Illumination will turn off automatically if an alarm starts to sound while Flash Alert is •
turned off. When Flash Alert is turned on, illumination will flash with the alarm.
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.
More than 15 degrees
too high
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.

Press 3. D to toggle Flash Alert on and off.
• The Flash Alert on indicator is shown on the display in
all modes while this function is turned on.
Press 4. A to exit the setting screen.
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 after the preset illumination duration •
(see “To specify the illumination duration”), 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 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.
