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. Be 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.
• Never try to remove or replace the watch’s special battery yourself. Use of
the wrong type of battery can damage the watch.
• All data stored in memory is deleted, and the current time and all other
settings return to their initial factory defaults whenever battery power drops
to Level 5 and when you have the battery replaced.
• Turn on the watch’s Power Saving function and keep it 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 Indicator and Recover Indicator
The battery power indicator on the display shows you the current status of the
rechargeable battery’s power.

• The flashing LOW indicator at Level 3 tells you that battery power is very
low, and that exposure to bright light for charging is required as soon as
possible.
• At Level 5, all functions are disabled and settings return to their initial
factory defaults. Once the battery reaches Level 2 (indicated by M indicator)
after falling to Level 5, reconfigure the current time, date, and other
settings.
• Display indicators reappear as soon as the battery is charged from Level 5
to Level 2.
• Leaving the watch exposed to direct sunlight or some other very strong light
source can cause the battery power indicator to show a reading temporarily
that is higher than the actual battery level. The correct battery level should
be indicated after a few minutes.
• Performing multiple sensor, illumination, or
beeper operations during a short period may
cause LMH (recover) to appear on the display.
Illumination, alarm, countdown timer alarm,
hourly time signal, and sensor operations will
be disabled until battery power recovers.
After some time, battery power will recover and
LMH (recover) will disappear, indicating that
the above functions are enabled again.
• Even if battery power is at Level 1 or Level 2, the Barometer/Thermometer
Mode or Altimeter Mode sensor may be disabled if there is not enough
voltage available to power it sufficiently. This is indicated by LMH (recover)
on the display.
• If LMH (recover) appears frequently, it probably means that remaining
battery power is low. Leave the watch in bright light to allow it to charge.

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.
Also note that allowing the watch to become very hot can cause its liquid
crystal display to black out. The appearance of the LCD should become
normal again when the watch returns to a lower temperature.
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
Charging Guide
After a full charge, timekeeping remains enabled for up to about five months.
• The following table shows the amount of time the watch needs to be
exposed to light each day in order to generate enough power for normal
daily operations.
• Since these are the specs, we can include all the technical details.
• Watch not exposed to light
• Internal timekeeping
• Display on 18 hours per day, sleep state 6 hours per day
• 1 illumination operation (1.5 seconds) per day
• 10 seconds of alarm operation per day
• 1 hour of altimeter measurement at 5-second interval, once per month
• 2 hours of barometric pressure measurement per day
• 6 minutes of signal reception per day
• Stable operation is promoted by frequent exposure to light.

Read This Before You Set the Time and Date!
This watch is preset with a number of city codes, each of which represents the
time zone where that city is located. When setting the time, it is important that
you first select the correct city code for your Home City (the city where you
normally use the watch). If your location is not included in the preset city codes,
select the preset city code that is in the same time zone as your location.
• Note that all of the times for the World Time Mode city codes are displayed
in accordance with the time and date settings you configure in the
Timekeeping Mode.
