Operation Guide 2674
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
Auto Display continually changes the contents of the
digital display.
To turn off Auto Display
Press any button (except for B) 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.
Auto Return Features
If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch automatically saves any settings you
have made up to that point and exits the setting screen.
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 Mode, the data you were viewing when you last
exited the mode appears first.
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
00
reset to
without changing the minutes.
• The year can be set in the range of 2000 to 2039.
• 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
• The seconds count of the World Time is synchronized with the seconds count of the
Timekeeping Mode.
• The current time in all World Time Mode cities is calculated in accordance with the
Greenwich Mean Time (GMT) differential for each city, based on the current Home
City time setting in the Timekeeping Mode.
• The GMT differential is the time difference of the time zone where the city is located
from Greenwich Mean Time.
• GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC) data.
Auto Time Display Precautions
• The watch may not display the current time if its face is
More than 15 degrees
more than 15 degrees above or below parallel. Make
too high
sure that the back of your hand is parallel to the ground.
• The watch returns to the Animation Mode in about three
seconds, even if you keep the watch pointed towards
your face.
• Static electricity or magnetic force can interfere with
proper auto time display. If the watch does not display
the current time automatically, 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, the watch may not display the current time until about one
second after you turn the face of the watch towards you. This does not necessarily
indicate malfunction.
• 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 auto time display,
and does not indicate a problem with the watch.
Backlight Precautions
The backlight uses an EL (electro-luminescent) panel that causes the entire display to
glow for easy reading in the dark.
In any mode, press B to illuminate the display for about two seconds.
• The electro-luminescent panel that provides illumination loses power after very long
use.
• The illumination provided by the backlight 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.
• The backlight automatically turns off whenever an alarm sounds.
• Frequent use of the backlight shortens the battery life.
