17. Notes Regarding Handling of this Watch
<Try to keep the watch charged at all times.>
• Please note that if you routinely wear long sleeves, the watch can easily
become insufficiently charged as a result of it being concealed and unable to
be exposed to light.
• When you take the watch off, try to place it in as bright a location as possible
to ensure that it always keeps the correct time.
Notes Charging Precautions
• Avoid recharging at high temperatures (over about 60°C / 140°F) since this
may result in damage to the watch as a result of reaching excessively high
temperatures.
Examples: Charging the watch in close proximity to an incandescent lamp,
halogen lamp or other light source that can easily reach high temperatures,
charging the watch in a location that reaches high temperatures such as on a
car dashboard.
• When charging the watch with an incandescent lamp or halogen lamp and so
forth, always make sure the watch is at least 50 cm (20 in.)away from the
lamp so that it does not reach excessively high temperatures during
charging.
