2. Getting Started

Initial Charging

Upon receiving your Casio WS220-1A watch, it is recommended to expose it to light for initial charging. The watch is equipped with Tough Solar technology, which converts light into electrical energy to power the watch and recharge the internal battery. For optimal performance, ensure regular exposure to light.

• Place the watch in a location where it can receive direct sunlight or bright artificial light.
• Avoid prolonged storage in dark places to prevent the battery from depleting.
• The display may indicate the battery level (H, M, L for High, Medium, Low). Aim to keep it at 'H'.

Basic Time Setting

The watch typically comes pre-set with the correct time. However, if adjustment is needed, refer to the detailed instructions in the full user manual for your specific module number. Generally, time setting involves entering a setting mode using the 'Adjust' button and then using other buttons to change values.

4. Care and Maintenance

Solar Charging Guidelines

To ensure continuous operation and extend battery life, regularly expose your watch to light. The solar panel is located on the watch face.

• Daily Exposure: Wear the watch regularly or place it in a well-lit area.
• Full Charge: For a nearly depleted battery, a full charge may require several hours of direct sunlight.
• Avoid Obstruction: Ensure the watch face is not covered by clothing or other objects when charging.

Water Resistance

The Casio WS220-1A is water-resistant to 100 meters (10 BAR), meaning it is suitable for everyday use, swimming, and snorkeling. It is not recommended for scuba diving.

• Do not operate buttons while the watch is submerged in water.
• Avoid exposing the watch to hot water or steam, as this can damage seals.
• Rinse the watch with fresh water after exposure to saltwater.

Battery Information

The watch uses a rechargeable Lithium Metal battery (included) that is charged by the Tough Solar system. With proper care and regular light exposure, the battery is designed for long-term use without replacement.

5. Troubleshooting

Blank Display or Low Battery Indicator

• Cause: Insufficient light exposure leading to low battery charge.
• Solution: Place the watch in direct sunlight or under bright artificial light for several hours to recharge.

Incorrect Time Display

• Cause: Time zone setting is incorrect or manual adjustment is needed.
• Solution: Enter Timekeeping Mode and adjust the home city/time zone. If necessary, manually set the time according to the full user manual.

Buttons Not Responding

• Cause: Watch may be in a locked mode, or battery is extremely low.
• Solution: Ensure the watch is not in a special mode (e.g., setting mode). Recharge the watch if the battery indicator is low. If the issue persists, perform a full reset (refer to the full user manual for specific instructions, as this may clear all settings).
