Things to check before using the watch

1. Check the Home City and the daylight saving time (DST) setting.

Use the procedure under “To conﬁ gure Home City settings” (page E-14) to conﬁ gure 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 conﬁ gure these settings correctly.

2. Set the current time.

See “Conﬁ guring 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 trafﬁ c accident and serious personal injury.

Auto light precautions

• See the seq uence in step 2 of t he procedure u nder “To change th e current

time and date set tings” (page E-17) for information abo ut how to scroll th rough setting screens.

3. Press D to toggle the button operation tone setting between enabled ( disabled (

4. After the setting is the way you want, press A to exit the setting screen.

Note

• The mute indi cator is displayed i n all modes whe n the button o peration ton e is

disabled.

• 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.
