Maintenance
Proper care and maintenance will extend the lifespan of your POLVCDG X34 earphones.
- Water Exposure: Do not soak the earphones in seawater or saltwater for extended periods. After use in water, rinse the charging magnetic part with fresh water and wipe it dry.
- Cleaning: After each exercise, wipe any water or sweat from the surface of the earphones, especially the charging magnetic suction port. Clean it promptly to prevent corrosion from sweat and saltwater, which can affect the product's lifespan.
- Storage: If not used for a long time, charge the earphones at least once a month to maintain battery health.
- Environmental Conditions: Keep the product away from fire, heat sources, freezing temperatures, and chemicals. Avoid violent impacts, disassembly, and extrusion of the product.
- Charging Adapter: Use a charging head with an output of 5V/1A or less. Using a charger with an output greater than 5V may cause the earphones to overheat, potentially damaging the battery and motherboard.

Troubleshooting
Important Warnings:
- Magnetic Charging: The magnetic charging has positive and negative poles. Mutual adsorption allows for normal charging. If the magnets repel, charging will not occur and may even cause a short circuit.
- Battery Disposal: The rechargeable battery must be disposed of properly for recycling. Do not put the battery into fire to avoid explosions.
Common Issues:
- No Power: Ensure the earphones are fully charged. If the battery is low, charge it for 2 hours.
- Cannot Pair: Make sure the earphones are in pairing mode (white and green lights flashing alternately). Check that Bluetooth is enabled on your device and search for "X34".
- No Sound/Distorted Sound: Check the volume levels on both the earphones and your connected device. If using MP3 mode, ensure the audio files are correctly loaded.
- Disconnection: Ensure the earphones are within the 8-10 meter effective range of your Bluetooth device. Avoid obstacles that may interfere with the signal.
- Product Defect: If you find the product defective, stop using it immediately. Do not disassemble any part of the product without permission. Contact customer support for assistance.
