To turn the auto light switch on and off

In the Timekeeping Mode, hold down 

L

 for about one second to toggle the auto light

switch on (

 displayed) or off (

 not displayed).

The auto light switch indicator is on the display in all modes while the auto light
switch is turned on.

In order to protect against running down the battery, the auto light switch turns off
automatically approximately six hours after you turn it on. Repeat the above
procedure to turn the auto light switch back on if you want.

Auto Return Features

If you leave the watch in the e-DATA MEMORY 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 exits the setting
screen. Except for password input, any settings you have made up to that point are
saved 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 e-DATA MEMORY, World Time, or Alarm 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 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 seconds count of the World Time is synchronized with the seconds count of 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.

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.

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 one second, 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.
