• 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 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.
• 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.
Tachymeter
If your watch has a tachymeter bezel, you can perform the
steps below to calculate average speed after using the
Stopwatch Mode to measure the amount of time that it
takes to travel one kilometer (or one mile).
• Never try to perform stopwatch operations while you
are driving an automobile, riding a bicycle, or
operating any type of vehicle. Doing so is very
dangerous and can result in accident.
1 In the Stopwatch Mode, start an elapsed time
operation at any point you like.
2 Stop the elapsed time operation after you travel one
kilometer or one mile.
3 Your average speed will be the value that the second
hand is pointing to on the tachymeter bezel.
• The illustration shows an example where it took 50 seconds to travel one kilometer
by car. The second hand is pointing at 70, which indicates that the average speed is
70 kilometers per hour.

• See “Stopwatch” for details about using the stopwatch.
• The tachymeter can be used only when you are traveling by car or some other
means that can cover one kilometer or one mile within 60 seconds.
