e-DATA MEMORY Mode, which you enter by pressing
C.
e-DATA MEMORY Management
e-DATA MEMORY can hold up to 315 characters total,
while each record can contain up to 63 characters. The
maximum number of records depends on the number of
characters per record, as shown below.
· 63 characters per record: 5 records
· 7 or fewer characters per record: 40 records
To create a new e-DATA MEMORY record
1. In the e-DATA MEMORY Mode, press D and B at the
same time to display the remaining memory screen.
· If 0 % is shown for remaining memory, it means that
memory is full. To store another record, you will first
have to delete some of the records stored in memory.
2. Hold down A until the flashing cursor ( #) appears on
the display, which indicates the setting screen.
· The setting screen also shows the record number that
is automatically assigned to the new record.
3. Input the text you want.
· When inputting the text, use D (+) and B (­) to
cycle through characters at the current cursor
location, and C to move the cursor to the right. See
"Inputting Text".

4. Press A to store your data and return to the e-DATA MEMORY record screen
(without the cursor).
· Pressing A causes the message SET to appear for about two seconds as the
data is stored. After that, the e-DATA MEMORY record screen appears.
· The text can show only three characters at a time, so longer text scrolls

Using a Password to Protect e-DATA MEMORY Data
You can register a 4-digit password to keep e-DATA MEMORY data secure.
Important!
Use a 4-digit password that is easy for you to remember, but difficult for others
to decipher. If you forget the password, you will have to have your watch
initialized (which deletes all data in memory) in order to access the e-DATA
MEMORY again. To have the watch initialized, contact the store or dealer where
you purchased it, and ask to have the AC operation performed.

Timekeeping Mode time and Home City code settings
and make the necessary changes.
· When the currently selected time zone is one that includes
mostly ocean, a value indicating the zone's Greenwich
Mean Time differential appears in place of a city code.
To toggle a city code time between Standard Time and Daylight Saving Time
1. In the World Time Mode, use B and D to display the
city code (time zone) whose Standard Time/Daylight

About the Auto Light Switch
Turning on the auto light switch causes the backlight to turn on for about one second,
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 the backlight to turn on.
Warning!
· Always make sure you are in a safe place whenever you are reading the
display of 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 the Timekeeping Mode, hold down L for about one second to toggle the auto light
switch on (
displayed) and off (
not displayed).
· With Module 2821, the auto light switch on indicator is
.
· The auto light switch on 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. Repeat the above
procedure to turn the auto light switch back on if you want.

3. Repeat steps 1 and 2 to input the rest of the characters you want.
· See the "Character List" for information about the characters you can input.
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.
Backlight Precautions
· 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.
Auto light switch precautions
· Wearing the watch on the inside of your wrist and movement or vibration of your arm
can cause the auto light switch to activate and illuminate the display. To avoid
running down the battery, turn off the auto light switch whenever engaging in
activities that might cause frequent illumination of the display.
· The backlight may not light 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.
· The backlight 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 the backlight
does not light, 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 backlight may not light until about one second after
you turn the face of the watch towards you. This does not necessarily indicate
malfunction of the backlight.
· 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.
