•

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.

• 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-38), 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.

3. Press C.

• This enters the hour and minute hand adjustment

mode.

4. If the hour and minute hands are not at 12 o’clock, use

and B to adjust them until they are.

5. Press A to return to the Timekeeping Mode.

Check to make sure that the time indicated by the hour and minute hands matches the time on the digital display. If the times don’t match, perform the correction procedure above again.

To enable or disable auto light

Illumination Precautions

• Illumination may be hard to see when viewed under direct sunlight.

• Illumination turns off automatically whenever an alarm sounds.

• Frequent use of illumination runs down the batteries.

In the Timekeeping Mode, hold down B for about three seconds to toggle auto light between enabled (indicator displayed) and disabled (indicator not displayed).

• The auto light enabled indicator appears in all modes

while auto light is enabled.

• Auto light remains enabled for about six hours. After
