Operation Guide 3270/3293
Power Supply
This watch is equipped with a solar panel and a rechargeable battery that is charged by the electrical power produced by the solar panel. The illustration shown below shows how you should position the watch for charging.
Example: Orient the watch so its face is | Solar panel |
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 panel is blocked by clothing, etc.
•You should try to keep the watch outside of your sleeve as much as possible. Charging
is reduced significantly if the face is covered only partially.
Battery Power Indicator and Recover Indicator
The battery power indicator on the display shows you the current status of the rechargeable battery’s power.

Charging Guide
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.
Exposure Level (Brightness) | Approximate |
| Exposure Time |
Outdoor Sunlight (50,000 lux) | 5 minutes |
Sunlight Through a Window (10,000 lux) | 24 minutes |
Daylight Through a Window on a Cloudy Day (5,000 lux) | 48 minutes |
Indoor Fluorescent Lighting (500 lux) | 8 hours |
•For details about the battery operating time and daily operating conditions, see the “Power Supply” section of the Specifications (page
•Stable operation is promoted by frequent exposure to light.
Reference
This section contains more detailed and technical information about watch operation. It also contains important precautions and notes about the various features and functions of this watch.
Moon Phase Indicator
Module 3270 | The Moon phase indicator of this watch indicates the | |
current phase of the Moon as shown below. It is based on | ||
| ||
| the view of the left side of the moon at meridian transit | |
| from the northern hemisphere of the Earth. If the | |
| appearance of the Moon phase indicator is reversed from | |
| the actual Moon as viewed from your location, you can | |
Moon Phase indicator | use the procedure under “To reverse the displayed Moon | |
Module 3293 | phase” (page |
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 rechargeable battery to store power produced by the solar panel, 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 rechargeable battery to charge fully, contact your dealer or CASIO distributor about having it replaced.
•Never try to remove or replace the watch’s rechargeable 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 (pages
•Turn on the watch’s Power Saving function (page
•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 after falling to Level 5, reconfigure the current time, date, and other settings.
•The watch’s Home City code setting will change automatically to TYO (Tokyo) whenever the battery drops to Level 5.
•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.
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
Recovery Times
The table below shows the amount exposure that is required to take the battery from one level to the next.
