Auto Return Features
• If you leave the watch in the Alarm Mode or Tide/Moon Data 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 on the display for two or three minutes
without performing any operation, the watch 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 during a scroll
operation scrolls at high speed.
Initial Screens
When you enter the World Time or Alarm Mode, the data you were viewing when you
last exited the mode appears first.
E-51
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 built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to change
it except after you have the watch’s battery replaced.
World Time
All World Time Mode times are calculated from the current time in the Timekeeping
Mode using UTC offset values.
• The seconds count of the World Time is synchronized with the seconds count of the
Timekeeping Mode.
• 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.
E-52
• 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
• Illumination may be hard to see when viewed under direct sunlight.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery.
E-53
More than 15 degrees
too high
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 in about 1.5 seconds 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.
E-54
• 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.
