Penyelenggaraan

Tahan Air

The Casio G-Shock G7900A-4 is water resistant to 200 meters (660 feet). This makes it suitable for professional marine activity and serious surface water sports. It is not recommended for scuba diving. To maintain water resistance, ensure all buttons are not operated while the watch is submerged. Avoid exposing the watch to hot water, steam, or chemicals (like those found in soaps or shampoos), as these can degrade the seals over time.

Penjagaan Am

• Clean the watch regularly with a soft, dry cloth. For stubborn dirt, use a mild soap solution and rinse thoroughly, then dry.
• Elakkan daripada mendedahkan jam tangan kepada suhu yang melampau, cahaya matahari langsung untuk tempoh yang lama atau medan magnet yang kuat.
• The resin band and bezel can be maintained using products designed for resin protection, such as Vinylex Quick Wipes, to prevent hardening or cracking over time.

Menyelesaikan masalah

Inaccurate Tide Graph Reading:

If your tide graph appears inaccurate after setting the lunitidal interval, try adding 7 hours to your calculated lunitidal interval value during setup. This adjustment has been noted to improve accuracy for some users.

World Time Discrepancies:

If certain World Time cities show an incorrect time, verify that the Daylight Saving Time (DST) setting is correctly configured for that specific city. Some regions may have unique DST rules or may not observe DST at all.

Dim Display or Weak Backlight:

This typically indicates a low battery. Replace the CR2025 battery. If the issue persists after battery replacement, consult a service center.
