About This Information

Please read this information before using your watch.

Battery

The battery is installed at the factory and should be replaced immediately when signs of insufficient power appear (e.g., dim display, no backlight) by your nearest CASIO dealer or distributor.

Water Protection

Watches are classified by water resistance ratings (I to V) according to their protection against water. Refer to the table below for correct usage.

Notes for Corresponding Ratings:

• Rating I: The watch is not water-resistant. Avoid any moisture.
• Rating II: Do not press the watch buttons underwater.
• Rating III: If the watch is exposed to saltwater, rinse it thoroughly with fresh water and wipe dry.
• Rating IV: The watch can be used for scuba diving (excluding depths requiring a helium-oxygen mixture).
• Rating V: Some water-resistant watches feature leather straps. Do not wear these watches for swimming or any other activity that may get the strap wet.

Caring for Your Watch

• Never attempt to open the case or remove the back cover yourself.
• The gasket, which protects the watch from water and dust, should be replaced every 2-3 years.
• If water enters the watch, have it checked immediately by your nearest CASIO dealer or distributor.
• Do not expose the watch to extreme temperatures.
• While designed for normal use, avoid rough handling and dropping the watch.
• Do not wear the strap too tightly. A finger should fit between your wrist and the strap.
• To clean the watch and strap, use a dry soft cloth or a soft cloth dampened with a mild neutral detergent solution. Never use volatile substances like gasoline, solvents, or spray cleaners.
• When not in use, store your watch in a dry place.
• Avoid contact with gasoline, cleaning solvents, spray aerosols, adhesives, paint, etc. Chemical reactions from these materials can damage gaskets, the case, and the watch's finish.
• Some models have silk-screened designs on their straps. Clean these straps carefully to avoid damaging the designs.

For Watches with Plastic Straps:

• A white powdery substance may appear on the strap. This substance is harmless to skin and clothing and can be easily removed by wiping with a cloth.
• Exposure of plastic straps to sweat or moisture, or storage in high humidity conditions, can lead to damage, breakage, or cracking. To ensure a long service life for plastic straps, wipe off dirt and water with a soft cloth whenever possible.

For Watches with Fluorescent Cases and Straps:

• Prolonged exposure to direct sunlight may cause the fluorescent color to gradually fade.
• Prolonged contact with moisture may cause the fluorescent color to gradually fade. If moisture gets on the watch surface, wipe it off as soon as possible.
• Prolonged contact with any other wet surface may cause the fluorescent color to fade. Ensure the fluorescent surface is dry and avoid contact with other surfaces.
• Rubbing a surface with fluorescent paint against another surface may transfer the fluorescent paint.

CASIO COMPUTER CO., LTD. is not responsible for any damage that may occur from the use of this watch, nor does it accept claims from third parties.

General Description of Operating Modes

If the display changes continuously, demonstrating your watch's capabilities, refer to the "Automatic Display Functions" section to learn how to stop it.

Your watch has several modes: Current Time, Phone Book, Alarm, and Stopwatch. Use button 'C' to switch between modes.

Diagram: Watch face showing various indicators (TEL, FREE, ALM, 12-25) and graphical display elements. Buttons labeled A, B, C, D, EL.

Diagram: Illustrates mode transitions using button C: Current Time -> Phone Book -> Alarm -> Stopwatch.

Press button 'L' for backlight illumination for 3 seconds.

The current time display offers two formats: one showing the day of the week, and another showing a time graph. Press button 'B' to switch between these formats.

There are three types of time graph formats, which change automatically based on alarm settings:

• Format E-9: Displays when no alarm is set.
• Format E-10: Displays when an alarm is set for the current date. A reminder graphic appears, and the graph pulses to show time remaining until the alarm.
• Format E-11: Displays when less than an hour remains until the alarm.

How to Set Current Time and Date

1. In the Current Time mode, press button 'A'. The seconds digits will flash, indicating they are ready for setting.
2. Press button 'C' to cycle through the digits to be set: Seconds -> Hours -> Minutes -> Year -> Month -> Day -> Animation Graphic.
3. To set seconds: Press button 'D'. If the seconds are between 30 and 59, the minutes will increment by 1 when the seconds are reset to "00". If seconds are between 00 and 29, the minutes will not change.

Backlight

• Pressing button 'L' illuminates the display for 3 seconds at any time.
• The backlight uses an electro-luminescent source, which may lose brightness with prolonged use.
