[Insufficient Charge Warning Feature]
This feature indicates that the watch has become insufficiently charged when
the second hand changes from 1-second interval movement to 2-second interval
movement. When this occurs, promptly charge your watch. Furthermore, the
chronograph and alarm functions will not operate in this state.
[Over Charge Prevention Feature]
When the secondary battery becomes fully charged as result of light shining into the watch
dial (solar cell), the over charge prevention feature is activated automatically to prevent
the secondary battery from being charged further. This prevents the secondary battery as
well as timekeeping accuracy, functions and performance of the watch from deteriorating
no matter how much the watch is charged.
11. Handling Precautions
[Try to keep the watch charged at all times]
Please note that if you frequently wear long sleeves, the watch can easily become
insufficiently charged because of being hidden and not exposed to light. Try to keep the
watch charged especially during the winter.
CAUTION: Charging Precautions
• Avoid charging the watch at high temperatures (about 60°C/140°F or higher) since
allowing the watch to reach a high temperature during charging can cause deformation
or discoloration of external components as well as a malfunction of movement
components.
Examples:
• Charging by placing the watch too close to a light source that may become hot such
as an incandescent lamp or halogen lamp.
• Charging by placing the watch on an automobile dashboard that can easily reach a
high temperature.
• When charging the watch with an incandescent lamp, halogen lamp or other light source
that may reach a high temperature, always make sure to place the watch at least 50 cm
(20 in.) away from the light source to prevent the watch from reaching a high temperature.
