Operation Guide 3216
Power Supply
This watch is equipped with a solar cell and a rechargeable 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 | Solar cell |
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. Charging is reduced significantly if the face is
covered only partially.
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 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 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 and |
when you have the battery replaced. |
Recovery Times
The table below shows the amount exposure that is required to take the battery from one level to the next.

•The above exposure time values are all for reference only. Actual required exposure times depend on lighting conditions.
Tide Site Name
Selecting the Tide Site Name
The tide site names you can select depend on your current Home City setting.
•Select tide site names in the Timekeeping Mode.
•After configuring the settings for your Home City, press Aonce to display the tide site name selection screen.
•Note that the tide sites you can select are those located in the same time zone as your Home City. They are not necessarily located near your Home City.
To configure tide site settings
• 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.

1.In the Timekeeping Mode, hold down Afor about two seconds until the city code starts to flash. This is the setting screen.
•The watch will exit the setting screen automatically if you do not perform any operation for about two or three minutes.
2.Press A once to display the tide site name selection screen.
•The current tide site name will be on the display and SET will flash.
3.Use D(forward) and B(back) to scroll through the tide site names until the one you want is displayed.
•If the tide site name is longer than four characters, the name will scroll from right to left on the display.
•A tide site that does not have any data assigned to it displays the name “USER”.
4.When all of the settings are the way you want, press A to exit the setting screen.
•The tide graph in the Timekeeping Mode shows information for the site you select here.
•The tide site candidates are those with the UTC differential as the current Home City. If you cannot find the site you want, you can select “USER”.
•Only “USER” sites may be available for some cities.
• 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
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.
•Stable operation is promoted by frequent exposure to light.
•Setting an accurate high tide time will allow the watch to produce accurate tide readings. Especially when “USER” is selected as the site, make sure that you input an accurate high tide time.
•Only a “USER” site can be selected while UTC is selected as the Home City.
