§3. SOLAR POWER WATCH
This watch is powered not by an ordinary battery, but by converting light energy into electrical
energy.
A secondary battery is used in this watch to store electrical energy. This secondary battery is a
clean energy battery which doesn't use any toxic substances such as mercury. Once fully
charged, the watch will continue to run for about 6 months without further charging.
[Explain the following items to the user for comfortable use of this watch.]
<Good use of solar-powered watch>
• Since the energy source of this watch is light, expose it to light sufficiently to charge the battery
in it.
• The battery of this watch is never overcharged by exposing it to light.
• If the user wears long-sleeved clothes usually, the watch is covered and its battery may not be
charged sufficiently.
• The watch should be put on a well lit plance as long as possible for its normal operation while
it is not worn.
[Replacing the secondary battery]
Unlike ordinary silver-based batteries, the secondary battery used in this watch does not have to
be periodically replaced since it is able to be charged and discharged repeatedly.
