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 normally 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.
• The current time and all other settings return to their initial factory defaults whenever
battery power drops to Level 4 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.

• The flashing charge indicator ( CHG ) 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 4, all functions are disabled and settings return to their initial factory
defaults. Functions are enabled once again after the rechargeable battery is
charged, but you need to set the time and date, after the battery reaches Level 3
(indicated by the flashing charge indicator) from Level 4. You will not be able to
configure any of the other settings until the battery reaches Level 2 (no charge
indicator) after dropping to Level 4.
• Leaving the watch in direct sunlight or some other very strong light source can cause the
battery power indicator to show a reading that is momentarily higher than the actual
battery level. The correct battery power indicator should appear after a few minutes.
• If you use the light or alarms a number of times during a short period, the recover
indicator (RECOV) appears and the following operations become disabled until
battery power recovers.

After some time, battery power will recover and the recover indicator will disappear,
indicating that the above functions are enabled again.
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

Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
The time calibration signals transmitted from Rugby and Mainflingen includes both
Standard Time and DST data. When the Auto DST setting is turned on, the watch
switches between Standard Time and DST (summer time) automatically in
accordance with the Rugby and Mainflingen signals.
• The default DST setting is Auto DST (A) whenever you select LON , PAR , BER ,
or ATH as your Home City code.
• If you experience problems receiving the time calibration signal in your area, it is
probably best to switch between Standard Time and Daylight Saving Time (summer
time) manually.
To change the Daylight Saving Time (summer time) setting
1. In the Timekeeping Mode, hold down A until the city code starts to flash, which
indicates the setting screen.
2. Press C and the DST setting screen appears.
3. Use D to cycle through the DST settings in the sequence shown below.
Auto DST ( A ) DST off ( OF ) DST on ( ON )
4. When the setting you want is selected, press A to exit the setting screen.
• The DST indicator appears to indicate that Daylight Saving Time is turned on.
