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 turns off after a preset amount of time (1.5 or 3 seconds), even if you
keep the watch pointed toward 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 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 toward 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.
