• Do not use harsh chemicals or abrasive materials.

6.2 Storage

• Store the earbuds in their charging case when not in use.
• Keep the device away from extreme temperatures, direct sunlight, and high humidity.
• Avoid free fall or violent shock to the device.

6.3 Charging Alerts

• If the earbuds have not been used for more than 3 months, we recommend that you charge them.
• Please use a charger approved by FCC (Federal Communications Commission).
• Do not disassemble the earbuds.
• Children aged 12 and under require adult supervision.
• Do not expose the earbuds to high or low temperatures, and do not use the earbuds during a thunderstorm.

7. Troubleshooting

If you encounter any issues with your Csasan V90 Wireless Earbuds, please try the following steps:

• No Power: Ensure the earbuds and charging case are fully charged.
• Pairing Issues: Turn off Bluetooth on your device, place earbuds back in the case, then remove them and try pairing again. Ensure no other Bluetooth devices are interfering.
• Sound Quality: Ensure earbuds are clean and properly seated in your ears. Check the audio source device.
• Single Earbud Use: If you want to use a single earbud, just take one out of the case and connect it to your phone. When using two earbuds, manually turn off one earbud or put one back in the charging case, and you'll be able to use the other earbud alone.
