Important Information
Battery
The battery installed at the factory discharges during shipping and storage. When the first signs of insufficient power (dim display) appear, the battery must be replaced by an authorized CASIO service center or dealer.
Water Protection
For all categories of watches, the following are prohibited:
- Pressing buttons underwater.
- Adjusting the crown underwater.
- Unscrewing the crown underwater.
If the watch is exposed to salt water, rinse it thoroughly and wipe it dry.
Do not wear a watch with a leather strap while swimming. Avoid prolonged contact of leather straps with water.
Care for Specific Materials
Straps with Silk-Screened Images
Be careful when cleaning such straps to avoid damaging the printed designs.
Plastic Straps
You may find a white powdery substance on the strap. This substance is harmless to your skin or clothing and can be easily removed by wiping with a cloth. Sweat or moisture on a plastic strap, or storing it in high humidity conditions, can lead to damage, breakage, or cracking. To ensure a long service life for the plastic strap, wipe it clean of dirt and water with a soft cloth whenever possible.
Fluorescent Cases and Straps
Prolonged exposure to direct sunlight can cause the fluorescent color to gradually fade. Prolonged contact with moisture can also cause the fluorescent color to fade. Wipe off any moisture from the watch surface as soon as possible. Avoid contact with other surfaces. Strong friction of a surface with fluorescent paint against another surface can transfer the fluorescent color.

Active Display
When the Active Display is ON, the current time in Timekeeping Mode can be displayed in one of six styles. The choice of style depends on the values displayed when you tilt your watch towards or away from you. When the Active Display is ON, an animation of a dancing figure will periodically appear at the top of the display. This animation also appears when switching between modes, regardless of whether the Active Display is ON or OFF.
When the Active Display is OFF, you can choose one of five styles for the current time display in Timekeeping Mode. Regardless of whether the Active Display is ON or OFF, when you tilt the watch towards you, the digits change size, rotate, or alter their appearance based on the selected display style (one through five). The sixth display style is only available when the Active Display is ON.
You may hear a faint sound when moving the watch, which is due to the watch mechanism and not a malfunction.
