Digital Time and Date
Use the Timekeeping Mode to set and view a digital display of the current time and date.
When setting the digital time, you can also configure settings for summer time
(Daylight Saving Time or DST), your Home City code (the code for the city where you
normally use the watch), the 12/24-hour format, and the illumination duration.
· This watch is preset with a number of city codes, each of which represents the time
zone where that city is located. When setting the digital time, it is important that you
select the correct city code for your Home City. If your location is not included in the
preset city codes, select the preset city code that is in the same time zone as your
location.
· Note that all of the times for the World Time Mode city codes are displayed in
accordance with the digital time and date settings you configure in the Timekeeping
Mode.
· After you correctly set your Home City time and date, you can set the watch up for
timekeeping with a different city code simply by changing the Home City code in the
Timekeeping Mode.
To set the digital time and date
1. In the Timekeeping Mode, hold down A until the
seconds start to flash, which indicates the setting
screen.
2. Press C twice to move the flashing to the Home City
code setting (see the illustration below), and then use
B and D to select the code you want.
· Make sure you select your Home City code before
changing any other setting.
· For full information on city codes, see the "City Code
Table".

Display Illumination
Display illumination uses an EL (electro-luminescent)
panel that causes the entire display to glow for easy
reading in the dark. The watch's auto light switch
automatically turns on display illumination when you angle
the watch for reading towards your face.
· The auto light switch must be turned on (indicated by
the auto light switch indicator) for it to operate.
· See "Illumination Precautions" for more important
information.
To illuminate the display
In any mode (except when a setting screen is on the display), press B to turn on
illumination.
· The above operation turns on illumination regardless of the current auto light switch
setting.
· You can use the procedure below to select either one second or three seconds as
the illumination duration. When you press B, the illumination will remain on for about
one second or three seconds, depending on the current illumination duration setting.
To specify the illumination duration
1. In the Timekeeping Mode, hold down A until the
seconds start to flash, which indicates the setting
screen.
2. Press C nine times so the illumination duration setting
screen is on the display.
3. While the illumination duration setting is flashing, press
D to toggle the setting between one second ( ) and
three seconds ( ).
4. Press A to exit the setting screen.
About the Auto Light Switch
While the auto light switch is enabled, illumination turns on for about one second or
three seconds, whenever you position your wrist as described below in any mode.
Moving the watch to a position that is parallel to the ground and then tilting it
towards you more than 40 degrees causes illumination to turn on.

Warning!
····· Always make sure you are in a safe place whenever you are reading the watch
using the auto light switch. Be especially careful when running or engaged in
any other activity that can result in accident or injury. Also take care that
sudden illumination by the auto light switch does not surprise or distract
others around you.
····· When you are wearing the watch, make sure that its auto light switch is turned
off before riding on a bicycle or operating a motorcycle or any other motor
vehicle. Sudden and unintended operation of the auto light switch can create
a distraction, which can result in a traffic accident and serious personal injury.
To turn the auto light switch on and off
In any mode, hold down B for about two seconds to toggle the auto light switch on
(auto light switch indicator displayed) or off (auto light switch indicator 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
automatically turns off approximately six hours after you turn it on.

Operation Guide 3319/3781
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 through the data 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.
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.
· With the 12-hour format, the P (PM) indicator appears on the display for times in the
range of noon to 11:59 p.m. and no indicator appears for times in the range of
midnight to 11:59 a.m.
· With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
any indicator.
· 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 batteries replaced.
World Time
· The World Time Mode times are calculated from the current Home City time setting
in the Timekeeping Mode, using the Greenwich Mean Time (GMT) differentials
associated with each city code.
· The GMT differential is a value that indicates the time difference between Greenwich
Mean Time and the time zone where a city is located.
· GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC) data.
Illumination Precautions
· The electro-luminescent panel that provides illumination loses power after very long
use.
· Display illumination 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.
· Illumination automatically turns off whenever an alarm sounds.
· Frequent use of the light shortens the battery life.
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 or three 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 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.
