Cynnal a Chadw a Gofal
Glanhau Eich Oriawr
To maintain the appearance of your watch, wipe it regularly with a soft, dry cloth. For stubborn dirt, use a soft cloth dampened with water and a mild soap, then wipe dry. Avoid using chemical cleaners, solvents, or abrasive materials, as these can damage the resin case and strap.
Gwrthiant Dŵr
Your GMD-S5600-1ER watch is water resistant to 200 meters (20 BAR). This means it is suitable for showering, swimming, and diving. However, avoid operating buttons while the watch is submerged in water or wet, as this can compromise the water resistance seals. After exposure to saltwater, rinse the watch with fresh water and wipe it dry.
Amnewid Batri
When the battery needs replacement, it is highly recommended to take your watch to an authorized Casio service center or a reputable watch repair shop. Improper battery replacement can damage the watch and compromise its water resistance.
Datrys problemau
If you encounter issues with your watch, please refer to the following common problems and solutions:
- Mae'r arddangosfa'n wag neu'n dywyll: Efallai bod y batri'n isel neu wedi'i wagio. Amnewidiwch y batri.
- Nid yw'r botymau'n ymateb: Ensure the watch is not in a locked mode (if applicable, though this model typically doesn't have a lock). Try pressing the buttons firmly. If the issue persists, a reset may be required (consult a service center).
- Mae'r amser yn anghywir: Re-adjust the time and date settings as described in the "Setting the Time and Date" section. Ensure the correct city code and DST settings are applied.
