towards you at more than 40 degrees causes illumination to turn on.  
Wear the watch on the outside of your wrist.  
Auto Return Features

operation scrolls at high speed.  
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.  
Initial Screens  
When you enter the World Time or Alarm Mode, the data you were viewing when you  
last exited the mode appears first.  
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.

World Time  
All World Time Mode times are calculated from the current Home City time in the  
Timekeeping Mode using UTC time differential values.  
The seconds count of the World Time is synchronized with the seconds count of the  
Timekeeping Mode.  
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 UTCis 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 Earths  
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.  
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.  
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.
