Scrolling  
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.

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 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.
