BACKLIGHT
The backlight 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
the backlight when you angle the watch towards your
face.
· The auto light switch must be turned on (indicated by
the auto light switch on indicator) for it to operate.
· See "Backlight Precautions" for other important
information about using the backlight.
To turn on the backlight manually
In any mode, press L to illuminate the display for about one second.
· The above operation turns on the backlight regardless of the current auto light
switch setting.
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.
· Be sure to wear the watch on the outside of your left wrist while using the auto light
switch.
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.
Parallel to ground
More than 40
°
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 any mode, hold down L for about two seconds to toggle the auto light switch on
(
displayed) or off (
not displayed).
· The auto light switch on indicator (
) is on the display in all modes while the auto
light switch is turned on.

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.
Timekeeping
· With the 12-hour format, the P (PM) indicator appears to the left of the hour digits for
times in the range of noon to 11:59 p.m. and no indicator appears to the left of the
hour digits 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, with 24
indicator.
· The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in all modes.
· The day of the week is automatically displayed in accordance with the date (year,
month, and day) settings.
· The year can be set in the range of 2000 to 2039.
· The watch's built-in full automatic calendar automatically 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.
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 anything you have
input up to that point and exits the setting screen.
Data and Setting Scrolling
The C button is used to scroll through setting screen data on the display. In most
cases, holding down this button during a scroll operation scrolls through the data at
high speed.
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
· In order to protect against running down the battery, the auto light switch
automatically turns off approximately five hours after you turn it on.
· 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.
· 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 your face 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.
