Auto Return Features
∑ If you leave the watch in the e-DATA MEMORY, City Temperature, or Alarm Mode for
two or three minutes without performing any operation, it automatically changes to
the Timekeeping Mode.
∑ 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 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 e-DATA MEMORY, World Time, or City Temperature 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
reset to
00
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 world time that appears in the lower part of the Timekeeping Mode screen
always uses 24-hour format, regardless of the watch’s current 12/24-hour setting.
∑ 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.
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 L 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.
