7. Maintenance and Care

Proper care will extend the life of your Acer OHR306 earphones:

• Cleaning: Use a soft, dry cloth to wipe the earphones. For earbuds, gently remove any earwax buildup with a small brush or cotton swab. Do not use harsh chemicals or abrasive materials.
• Storage: When not in use, store the earphones in a clean, dry place away from direct sunlight and extreme temperatures. The magnetic earbuds help prevent tangling.
• Water Resistance: The earphones are waterproof, but avoid prolonged exposure to water or submersion. Dry them thoroughly if they get wet.
• Charging: Use only the provided Type-C cable or a certified equivalent. Avoid overcharging or charging in extreme heat/cold.
• Avoid Damage: Do not drop, disassemble, or modify the earphones. Keep them away from sharp objects.

8. Troubleshooting

If you encounter issues with your Acer OHR306 earphones, try the following solutions:

8.1 No Power

• Ensure the earphones are fully charged. Connect them to a power source using the Type-C cable and check the LED indicator.
• Try powering on again by long-pressing the multi-function button.

8.2 Cannot Pair with Device

• Make sure the earphones are in pairing mode (LED flashing rapidly).
• Ensure Bluetooth is enabled on your device and it is within 10 meters of the earphones.
• Turn off Bluetooth on your device, then turn it back on and try searching again.
• If previously paired, try forgetting the device in your phone's Bluetooth settings and re-pairing.
• Ensure no other Bluetooth devices are interfering with the connection.

8.3 No Sound or Low Volume

• Check the volume levels on both the earphones and your connected device.
• Ensure the earphones are properly connected to your device.

• Ensure the microphone is not obstructed.
• Move closer to your connected device to improve signal strength.
