6. Maintenance

6.1 Cleaning

• Regularly clean the earbuds, especially the eartips and charging contacts, with a soft, dry, lint-free cloth.
• Do not use abrasive cleaners, alcohol, or chemical solvents.
• Remove eartips and clean them separately with mild soap and water if necessary, ensuring they are completely dry before reattaching.

6.2 Storage

• Always store the earbuds in their charging case when not in use to protect them and keep them charged.
• Store the case and earbuds in a cool, dry place, away from extreme temperatures and direct sunlight.

6.3 Water Resistance (IPX7)

The Catitru i25 earbuds are IPX7 waterproof, meaning they can withstand immersion in water up to 1 meter for 30 minutes. This makes them suitable for sports and protection against sweat and rain.

• Do not intentionally submerge the earbuds for extended periods or in depths greater than specified.
• The charging case is not waterproof. Do not expose the charging case to water or moisture.
• Ensure earbuds are completely dry before placing them back into the charging case to prevent damage to the charging contacts.

7. Troubleshooting

If you encounter issues with your Catitru i25 earbuds, please refer to the following common solutions:

7.1 Earbuds Not Charging

• Ensure the charging cable is securely connected to both the case and the power source.
• Check if the charging contacts on both the earbuds and inside the case are clean and free of debris.
• Verify that the charging case has sufficient battery power.

7.2 Earbuds Not Pairing/Connecting

• Make sure Bluetooth is enabled on your device.
• Ensure the earbuds are fully charged and removed from the charging case.
• Turn off Bluetooth on other nearby devices to avoid interference.

7.3 Low Volume or Poor Sound Quality

• Ensure the eartips are properly sealed in your ear canal. Try different sizes of eartips for a better fit.
