Notes Regarding Handling of this Watch
<Try to keep the watch charged at all times.>
Please note that if you wear long sleeves, the watch can easily become insuffi-
ciently 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.
CAUTION
Charging Precautions
• Avoid recharging at high temperatures (over about 60°C/140°F) since this may
result in damage to the watch during recharging.
Examples: Charging the watch in close proximity to an incandescent lamp,
halogen lamp or other light source that can easily reach high temper-
atures, charging the watch in a location that reaches high tempera-
tures such as on a car dashboard.
• When charging the watch with an incandescent lamp, always make sure the
watch is at least 50cm (20in.) away from the lamp so that it does not reach
excessively high temperatures during charging.
