illuminating power after very long term use.
· Frequent use of the backligfht shortens the battery life.

EL light vibrates slightly when lit. It does not indicate malfunction of the watch.

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 accidents,
especially in locations where there might be vehicular or pedestrian traffic. 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 motorcycle
or any other motor vehicle. Doing so is dangerous and can result in a traffic accident
and serious personal injury.
· When you are wearing the watch, make sure that its auto backlight function is turned
off before riding on a bicycle or operating a motorcycle or any other motor vehicle.
Sudden and unintended operation of the auto backlight can create a distraction, which
can result in a traffic accident and serious personal injury.
