Illumination
The B and D buttons are used in various modes and setting screens to scroll
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 enabled (indicated by the
auto light switch indicator) for it to operate.
• See “Illumination Precautions” for more important
information.
through data on the display. In most cases, holding down these buttons scrolls at high
speed.
Initial Screens
When you enter the Timekeeping, World Time, or Alarm Mode, the data you were
viewing when you last exited the mode appears first.
World Time
• The seconds count of the World Time is synchronized with the seconds count of the
Auto light switch indicator
Timekeeping Mode.
• All World Time Mode times are calculated from the current Home City time in the
Timekeeping Mode using UTC time offset values.
To illuminate the display
In any mode (except when a setting screen is on the display), press B to turn on
• 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.
• The above operation turns on illumination regardless of the current auto light switch
setting.
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.
Illumination Precautions
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.
• 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.
More than 40°
Parallel to ground
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery.
Auto light switch precautions
Warning!
• 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.
• 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.
• Illumination may not turn on if the face of the watch is
More than 15 degrees
too high
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 seconds, even if you
keep the watch pointed towards your face.
• 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.
• 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.
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 indicator displayed) or off (auto light switch indicator
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.
• 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.
Button Operation Tone
The button operation tone will sound any time you press
one of the watch’s buttons. You can turn the button
operation tone on or off as desired.
• The daily alarm and countdown alarm tones continue to
sound even if you turn off the button operation tone.
