Impostare

Impostazione iniziale di data e ora

Upon first use or after a battery change, you will need to set the current time and date. Refer to the detailed instructions in the full user manual for specific button operations. Generally, you will use the 'MODE' button to navigate through settings and 'ADJUST' or 'START/STOP' buttons to change values.

Setting Tide and Moon Data

To utilize the tide graph and moon data features, you must input your current location's longitude and lunitidal interval. This allows the watch to accurately calculate tide levels and moon phases for your specific area. Consult the comprehensive manual for precise input procedures.

Informazioni sulla batteria

The G7900-1 uses a CR2025 battery, providing an approximate battery life of 2 years. When the display becomes dim or functions are erratic, it may be time to replace the battery. It is recommended to have battery replacement performed by a qualified technician to ensure water resistance integrity.

Manutenzione

Pulizia dell'orologio

Regularly clean your watch with a soft, dry cloth. For stubborn dirt, use a mild soap solution and a soft brush, then rinse thoroughly with fresh water and dry completely. Avoid using chemical cleaners or solvents as they may damage the watch's materials.

Cura della resistenza all'acqua

While your G-Shock is water resistant to 200 meters, it is important to rinse the watch with fresh water after exposure to saltwater or chlorine to prevent corrosion. Do not operate buttons while the watch is submerged in water or wet, as this can compromise the water resistance seals.

Sostituzione della batteria

When the battery needs replacement, it is highly recommended to have it done by an authorized Casio service center or a professional watch repair shop. This ensures that the watch's water resistance is properly re-sealed and maintained after the battery compartment is opened.

Risoluzione dei problemi

Il display è scuro o vuoto

This usually indicates a low battery. Replace the CR2025 battery. If the issue persists after battery replacement, contact customer support.

Il tempo è impreciso

Manually adjust the time settings as described in the "Setup" section. Note that the watch has an accuracy of +/- 15 seconds per month. If the deviation is significantly greater, a professional inspection may be required.

I pulsanti non rispondono

Ensure the watch is not in a locked mode (if applicable, though G7900-1 typically doesn't have a button lock). If buttons are stuck, gently clean around them. If the problem persists, it may indicate an internal mechanism issue requiring professional service.

Acqua all'interno dell'orologio

Immediately take the watch to an authorized service center. Do not attempt to open the watch yourself, as this will void the warranty and likely cause further damage. Water intrusion can lead to irreversible damage to the internal components.
