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.
1. In the Alarm Mode, use D to scroll through the alarm
screens until the one whose time you want to set is
displayed.
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.
• Wear the watch on the outside of your wrist.
• To set a one-time alarm, display one of the screens indicated by an alarm number
from AL1through AL4. To set the snooze alarm, display the screen indicated
by SNZ.
Parallel to ground
More than 40°
• The snooze alarm repeats every five minutes.
2. After you select an alarm, hold down A until the hour setting of the alarm time
starts to flash, which indicates the setting screen.
• This operation automatically turns on the alarm.
3. Press C to move the flashing between the hour and minute settings.
4. While a setting is flashing, use D (+) and B (–) to change it.
• When setting the alarm time using the 12-hour format, take care to set the
time correctly as a.m. (no indicator) or p.m. (PM indicator).
5. Press A to exit the setting screen.
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.
Alarm Operation
The alarm sounds at the preset time for about 20 seconds, regardless of the mode the
watch is in. In the case of the snooze alarm, the alarm operation is performed a total
of seven times, every five minutes, or until you turn the alarm off.
• Alarm and Hourly Time Signal operations are performed in accordance with the
Timekeeping Mode digital time.
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.
• To stop the alarm tone after it starts to sound, press any button.
• Performing any one of the following operations during a 5-minute interval between
snooze alarms cancels the current snooze alarm operation.

• The UTC differential is a value that indicates the time difference between a
reference point in Greenwich, England and the time zone where a city is located.
• The letters “UTC” is the abbreviation for “Universal Time Coordinated”, which is the
world-wide scientific standard of timekeeping. It is based upon carefully maintained
atomic (cesium) clocks that keep time accurately to within microseconds. Leap
seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s
rotation.

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.
More than 15 degrees
too high
• 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.
