4. Maintenance

• Keep the charger clean and dry. Use a soft, dry cloth to wipe the surface.
• Avoid exposing the charger to extreme temperatures, humidity, or direct sunlight.
• Do not attempt to disassemble or repair the charger yourself. Contact customer support if issues arise.
• Store the charger in a cool, dry place when not in use.

5. Troubleshooting

• Charger not powering on: Ensure the USB cable is fully inserted into both the charger and the power source. Try a different USB port or power adapter.
• Battery not charging:
  • Verify that the battery is correctly inserted into the slot and making proper contact.
  • Ensure the battery is compatible with the charger (Fujifilm NP-95 or Ricoh DB-90).
  • If the battery is severely depleted, it might take a few minutes for the charging indicator to activate.
  • Check if the battery itself is damaged or at the end of its lifespan.
• Charging stops unexpectedly: The charger has built-in overheat protection. If a battery becomes too hot, charging will pause. Allow the battery to cool down before attempting to charge again.
• LED indicators not functioning correctly: If the indicators do not behave as described (flashing during charge, solid when full), ensure the charger is connected to a stable power source and the batteries are properly seated. If the issue persists, the charger may be faulty.
