10. Helpful Hints in Using your Watch

Exposing this watch to light (1,000 lux or more) for at least 3 hours per day or wearing
the watch for at least 12 hours per day will enable it to obtain the amount of charging
required to power the watch for approximately 1 day. The amount of charging varies
con-
A
depending on the intensity of the light to which the watch is exposed, the manner in
which the watch is worn and individual differences, however.
<When the Watch is Worn Daily>
If the watch is exposed to light daily or worn daily for at least 12 hours, the watch will
be additionally charged each day. This will enable the watch to run continuously with-
out intentionally charging. When the watch is used where there are low levels of light or
when the amount of movement of the watch is low, such as during long periods of desk
work, the watch should occasionally be charged by swinging.
<When the Watch is Worn for Short Periods (Several Days)>
When the amount of time the watch is not worn is longer than the time it is worn, there
are few opportunities to expose the watch to light, or when the watch is not worn on the
wrist, the watch should occasionally be charged by swinging. If the watch is only worn
occasionally, it may stop before it is worn as a result of being undercharged. When this
happens, it is necessary to recharge the watch by exposing to light or swinging and then
reset the time prior to use.
