Things to check before using the watch
1. Check the Home City and the daylight saving time (DST) setting.
Use the procedure under “To configure Home City settings” (page E-14) to configure
your Home City and daylight saving time settings.
Important!
Proper World Time Mode data depends on correct Home City, time, and date settings
in the Timekeeping Mode. Make sure you configure these settings correctly.
2. Set the current time.
See “Configuring Current Time and Date Settings” (page E-17).
The watch is now ready for use.

About auto light
While auto light is enabled, illumination will 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.
Warning!
•Always make sure you are in a safe place whenever you are reading the
display of the watch using auto light. 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 auto light does not startle or distract others
around you.
•When you are wearing the watch, make sure that auto light is disabled before
riding on a bicycle or operating a motorcycle or any other motor vehicle.
Sudden and unintended operation of auto light can create a distraction, which
can result in a traffic accident and serious personal injury.

Auto light precautions
•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 after the preset illumination duration (page
E-40), even if you keep the watch pointed towards your face.
•Static electricity or magnetic force can interfere with proper
operation of auto light. 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 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.
•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 auto light, and does not indicate a
problem with the watch.
E-44
Button Operation Tone
When enabled, the button operation tone sounds any time you press one of the
watch’s buttons. You can enable or disable the button operation tone as desired.
•Even if you disable the button operation tone, the alarm, Hourly Time Signal, and
Countdown Timer Mode alarm all operate normally.
To enable or disable the button operation tone
1. In the Timekeeping Mode, hold down Auntil ADJ
appears in the lower display.
•When you release A(after ADJ appears), SET will
be flashing in the upper display.
2. Use Cto cycle through settings on the lower display
until the current button operation tone setting (MUTE or
KEY ) is shown.

disabled (MUTE).
4. After the setting is the way you want, press Ato exit the setting screen.
Note
•The mute indicator is displayed in all modes when the button operation tone is
disabled.
E-46
Low Battery Indication
A low battery indicator appears on the display when the power of the batteries is low.
Have the batteries replaced as soon as possible.
Note
•For guidelines covering the life of the batteries and supported battery types,
see “Specifications” (page E-50).
The conditions below are in effect while the low battery indicator is flashing.
•All hands are stopped.
•Except for the low battery indicator, all other display
functions are disabled.
•Watch tones are disabled.
•Display illumination is disabled.
•Watch operations are disabled.
Low battery indicatorLow battery indicator
E-47
Note
•Sequentially or repeatedly performing light, alarm, and other power intensive
operations over a short period can cause a sudden drop in battery power,
which will make the low battery indicator flash. Even though the low battery
indicator may disappear and watch functions may become re-enabled, battery
replacement is recommended.
E-48
Troubleshooting
Time Setting
■ The current time setting is off by a couple of hours.
Your Home City setting may be wrong (page E-14). Check your Home City setting and
correct it, if necessary.
■ The current time setting is off by one hour.
You may need to change your Home City’s standard time/daylight saving time (DST)
setting. Use the procedure under “To change the current time and date settings” (page
E-17).
World Time Mode
■The time for my World Time City is off in the World Time Mode.
This could be due to incorrect switching between standard time and daylight saving
time.
See “To configure World Time City and summer time settings” (page E-26) for more
information.
E-49
Batteries
■The low battery indicator is flashing on the digital display.
The watch’s battery power is low. Have the batteries
replaced as soon as possible.
