between Regular and Reverse automatically every 12 hours.
• See “Main Display Area Style” for information about changing the main display area

Illumination
Auto light switch indicator
To illuminate the display
In any mode (except when a setting screen is on the display), press B to turn on
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.
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.
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 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.
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 Zoom
In any mode besides the Edit Mode (and except while any setting screen is displayed
and while an icon is displayed immediately after entering a mode), angling the watch
towards your face for viewing will cause the figures in the main display area to enlarge
automatically.
• The figures will return to normal size after about two seconds or if you perform any
button operation.
• For more information about the arm position that triggers Auto Zoom, see “About the
Auto Light Switch”.

Operation Guide 3077
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 Display
Dot Animation
Four dots in the upper right corner of the display appear and disappear during certain
watch operations. This animation is for appearance purposes only.
Auto Return Features
• If you leave the watch in the Alarm or Edit 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 or a cursor on the display for two or three
minutes without performing any operation, the watch saves any settings you have
made up to that point and exits the setting screen automatically.
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 scrolls at high
speed.
Initial Screens
When you enter the Timekeeping, World Time, Alarm or Edit 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
Timekeeping Mode.
• All World Time Mode times are calculated from the current Home City time in the
Timekeeping Mode using UTC time differential values.
• The UTC differential 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
• 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 alarm sounds.
• 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.
Auto Display causes the Timekeeping Mode main display
area to switch between Regular and Reverse every five
seconds.
To turn off Auto Display
Press any button to turn off Auto Display.
To turn on Auto Display
In the Timekeeping Mode, hold down C for about three
seconds until the watch beeps.
• Note that Auto Display cannot be performed while a
setting screen is on the display.
• 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 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 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.
