C. Time Required for Charging
Since time required for recharging the battery varies according to model
(depending on the dial color, etc.), refer to the following table as a rough
guideline for charging the rechargeable battery.
Charging time required for fully charging:
Time required for fully charging the battery, starting from the state
that the watch has stopped operation (in the stop warning indication).
Charging time for one-day operation:
Time required for charging the battery enough for running the watch for
one day, starting from the state that the second hand normally goes
every second.
(Note) For using the watch for diving (one-hour diving a day), time
required for charging must be extended 1.5 times as long as the
time appearing in the table.
D. Special Care for this Solar Powered Watch
<Always take care to charge the battery of the watch. >
* Mind that the battery power is likely to decline if you wear a jacket
or a long sleeve shirt, because the watch is usually shaded by such
clothes and the battery is insufficiently charged as a result.
* Try to put the watch in a well-lit place, as far as circumstances
permit, when you take it off. If you do, the watch will continue normal
running.
- Notes on charging -
* Avoid charging in a hot place where the ambient temperature is
+60'C/140'F or more, because an extreme rise in temperature may cause a
breakdown of the watch.
Examples: Charging near a hot light source such as an incandescent
lamp, halogen lamp, etc. Charging in a place that easily
becomes hot such as on a car dashboard, etc.
- When the watch is exposed to an incandescent lamp for charging,
carefully keep the watch 50 cm (20 in.) or more apart from it so as not
to get the watch hot.
