About the Auto Light Switch
Turning on the auto light switch causes illumination to turn on, 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.
• Wear the watch on the outside of your wrist.
Parallel to

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
startle or distract others around you.
••••• When you are wearing the watch, make sure that its auto light switch is turned
off before riding 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 B for about three seconds to toggle the auto
light switch on (auto light switch on indicator displayed) and off (auto light switch on
indicator not displayed).
• The auto light switch on indicator remains in all modes while the auto light switch is
turned on.
• In order to protect against running down the battery, the auto light switch will turn 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.

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.
Auto Return Feature
• If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch saves any settings you have made up to
that point and exits the setting screen automatically.
• The watch will change to the Timekeeping Mode automatically if you do not perform
any operation in the Recall Mode or Alarm Mode for two or three minutes.
E-43
Button Operation Tone
The button operation tone sounds any time you press one
of the watch’s buttons. You can turn the button operation
tone on or off as desired.
• The multi-function alarms and Countdown Timer Mode
alarm will sound even if the button operation tone is
turned off.
To turn the button operation tone on and off
In any mode (except when a setting screen is on the display), hold down C to toggle
the button operation tone on (mute indicator not displayed) and off (mute indicator
displayed).
• Holding down C to turn the button operation tone on or off also causes the watch’s
current mode to change.
• The mute indicator is displayed in all modes when the button operation tone is
turned off.
E-44
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.
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 2099.
• 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.
E-45
Illumination Precautions
• Illumination may be difficult 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 1.5 seconds or 3 seconds,
even if you keep the watch pointed towards your face.
More than 15 degrees
too high
E-46
• 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 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, 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.
