7.Replacing the Secondary Battery
Unlike ordinary batteries, the secondary battery used in this watch can be
repeatedly charged and discharged and is not required to be periodically
replaced.
CAUTION
Never use another battery different from the secondary battery used in this
watch.
The watch structure is so designed that a different kind of battery other than
that specified cannot be used to operate it. In case a different kind of battery
such as a silver battery is used by some chance, there is a danger that it will be
overcharged to burst, causing damage to the watch and even to the human
body.

6. Handling Precautions
<Try to Keep the Watch Charged at All Times>
Please note that if you wear long sleeves, the watch can easily become
insufficiently charged as a result of the watch being covered and not being
exposed to light. The watch will continue to run properly if it is placed in as
bright a location as possible even when not being worn.
Charging Precautions
· Allowing the watch to reach high temperatures during recharging can damage
the watch. Avoid recharging in locations that can reach high temperatures
(about 60°C /140°F or higher).
Examples: · Charging by placing the watch in close proximity to a light
source that easily becomes hot such as an incandescent lamp
or halogen lamp.
· Charging the watch in a location that can easily become hot
such as on an automobile dashboard
· When charging using the light from an incandescent lamp, charge while being
careful that the watch does not become excessively hot by placing at a
distance of at least 50 cm (20in) from the lamp
