Initial Screens
When you enter the World Time Mode 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 Timekeeping Mode.
Timekeeping
•Resetting the seconds to 00 while the current count is in the range of 30 to 59 causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to 00 without changing the minutes.
•The year can be set in the range of 2000 to 2099.
•The watch’s 
•The current time for all city codes in the Timekeeping Mode and World Time Mode is calculated in accordance with the Coordinated Universal Time (UTC) for each city, based on your Home City time setting.
Illumination Precautions
•The 
•Illumination may be difficult 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 | • Illumination may not turn on if the face of the watch is | |
| more than 15 degrees above or below parallel. Make | ||
| too high | ||
| 
 | sure that the back of your hand is parallel to the ground. | |
| 
 | • Illumination turns off after a preset amount of time (1.5 | |
| 
 | or 3 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 toward 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.
