Illumination
This watch has an EL (electro-luminescent) panel that
causes the entire display to glow for easy reading in the
dark. The auto light turns on illumination automatically
when you angle the watch towards your face for reading.

x See “Illumination Precautions” (page E-42) for more
important information.

About auto light
While auto light 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.
x Wear the watch on the outside of your wrist.

Warning!
x Always make sure you are in a safe place whenever you are reading the
watch using auto light. 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 auto light does not startle or distract others around you.
x When you are wearing the watch, make sure that auto light is disabled before
riding on a bicycle or operating a motorcycle or any other motor vehicle.
Sudden and unintended operation of auto light can create a distraction, which
can result in a traffic accident and serious personal injury.
To enable or disable auto light
In the Timekeeping Mode, hold down B for about three seconds to toggle auto light
between enabled (LT shown on the display) and disabled (LT not displayed).
x The auto light enabled indicator (LT) is on the display in all modes while auto light
is enabled.
x Auto light remains enabled for about six hours. After that it becomes disabled
automatically.

Auto Return Features
x 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.
x 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.
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.
Initial Screens
When you enter the World Time or Alarm Mode, the data you were viewing when you
last exited the mode appears first.
E-40
x 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
x The electro-luminescent panel that provides illumination loses power after very long
use.
x Illumination may be hard to see when viewed under direct sunlight.
x 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.
x Illumination turns off automatically whenever an alarm sounds.
x Frequent use of illumination runs down the battery.

Auto light precautions
x 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 auto light.
x 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 auto light, and
does not indicate a problem with the watch.

degrees above or below parallel. Make sure that the back of your
hand is parallel to the ground.

x Static electricity or magnetic force can interfere with proper
operation of auto light. 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.
