§7. 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 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.
CAUTION – Charging Precautions –
• Avoid recharging at high temperatures (over about 60°C/140°F) since this may result in dam-
age 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 temperatures.
* Charging the watch in a location that reaches high temperatures such as on a car dash-
board.
* When charging the watch with an incandescent lamp, 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.
§8. REPLACING THE SECONDARY BATTERY
The secondary battery used in this watch does not have to be periodically replaced in the man-
ner of ordinary batteries since it is able to be charged and discharged repeatedly.
