Warning!
Never try to read your watch when mountain climbing or hiking in areas that
x
are dark or in areas with poor footing. Doing so is dangerous and can result in
serious personal injury.
Never try to read your watch when running where there is the danger of
x
accidents, especially in locations where there might be vehicular or pedestrian
traffi c. Doing so is dangerous and can result in serious personal injury.
Never try to read your watch when riding on a bicycle or when operating a
x
motorcycle or any other motor vehicle. Doing so is dangerous and can result
in a traffi c accident and serious personal injury.
When you are wearing the watch, make sure that its auto light switch function
x
is turned off before riding on a bicycle or operating a motorcycle or any other
motor vehicle.

Caution
The backlight of this watch employs an electro-luminescent (EL) light, which loses its
x
illuminating power after very long term use.
Frequent use of the backlight shortens the battery life.
x
The watch emits an audible sound whenever the display is illuminated. This is
x
because the EL light vibrates slightly when lit. It does not indicate malfunction of
the watch.
E-11

malfunction of the backlight.
