Power Supply
This watch is equipped with a solar cell and a special rechargeable battery
(secondary battery) that is charged by the electrical power produced by the
solar cell. The illustration shown below shows how you should position the
watch for charging.
Example: Orient the watch so its face is
pointing at a light source.
• The illustration shows how to position a
watch with a resin band.
• Note that charging efficiency drops when
any part of the solar cell is blocked by
clothing, etc.
• You should try to keep the watch outside
of your sleeve as much as possible. Even
if the face of the watch is blocked from
light only partially, charging will be
reduced significantly.
Solar cell
Important!
• Storing the watch for long periods in an area where there is no light or
wearing it in such a way that it is blocked from exposure to light can cause
rechargeable battery power to run down. Make sure that the watch is
exposed to bright light whenever possible.
• This watch uses a special rechargeable battery to store power produced by
the solar cell, so regular battery replacement is not required. However, after
very long use, the rechargeable battery may lose its ability to achieve a full
charge. If you experience problems getting the special rechargeable battery
to charge fully, contact your dealer or CASIO distributor about having it
replaced.
• The special rechargeable (secondary) battery used by your watch is not
intended to be removed or replaced by you. Use of a rechargeable battery
other than the special one specified for this watch can damage the watch.
• The current time and all other settings return to their initial factory defaults
whenever battery power drops to Level 3 and when you have the battery
replaced.
• Keep the watch in an area normally exposed to bright light when storing it
for long periods. This helps to keep the rechargeable battery from going
dead.
Battery Power Levels
The movement of the analog hands indicates the current battery power level.
Hand Movement
Normal.
• Second hand jumps
every 2 seconds.
• Date changes to

analog timekeeping
and stopwatch.
All functions
disabled.
Jumps 2 seconds
• The second hand jumping every two seconds (Level 2) indicates that
battery power is quite low. Expose the watch to light as soon as possible to
charge the battery.
• When battery power is at Level 2, time calibration signal reception is
disabled.
• At Level 3, all functions are disabled and settings return to their initial
factory defaults. The watch will continue to keep time internally for about
one month after the battery drops to Level 3. If you recharge the battery
sufficiently during this period, the analog hands will move automatically to
the correct setting and normal timekeeping will resume.
• Alarm operation can cause hand movement to stop due to the sudden
temporary drop in battery power. This does not indicate malfunction, and
normal operation will resume when the watch is exposed to light. Though
hand movement stops, timekeeping continues internally, and the hands will
be adjusted to the correct setting when normal operation returns.
Charging Precautions
Certain charging conditions can cause the watch to become very hot. Avoid
leaving the watch in the areas described below whenever charging its
rechargeable battery.
Warning!
Leaving the watch in bright light to charge its rechargeable battery can
cause it to become quite hot. Take care when handling the watch to
avoid burn injury. The watch can become particularly hot when exposed
to the following conditions for long periods.
• On the dashboard of a car parked in direct sunlight
• Too close to an incandescent lamp
• Under direct sunlight
