4. Setup

4.1 Charging the Headset

The headset has a built-in rechargeable battery. For first use, ensure the battery is fully charged. When the headset prompts with a “Di-Di” sound, it indicates low battery and requires charging.

1. Connect the magnetic charging cable to the headset's magnetic charging port.
2. Connect the other end of the cable to a 5V 1A (or less) USB power adapter. Do not use fast chargers.
3. The indicator light will show a red breathing light during charging.
4. Charging typically takes about 2 hours. Once fully charged, the indicator light will turn solid blue.

Warning:

• Ensure correct magnetic polarity when connecting the charger; mutual repulsion means incorrect connection and can cause short circuits.
• The rechargeable battery must be disposed of properly for recycling. Do not put the battery into fire to avoid explosion.

4.2 Bluetooth Pairing

To connect your headset to a Bluetooth-enabled device (e.g., smartphone, computer):

1. Ensure the headset is powered off.
2. Press and hold the Power On/Mode Key for 3-5 seconds until the indicator light flashes red and blue alternately. This indicates pairing mode.
3. On your device, enable Bluetooth and search for available devices.
4. Select “X7” from the list to connect. Once connected, the indicator light will flash blue slowly (every 5 seconds).

Note: The headset will automatically search for and connect to the last paired device upon powering on. If the headset is out of range (>10 meters) for an extended period, you may need to manually reconnect by clicking the Power On/Mode Key once it's back within range.

6. Maintenance and Cleaning

Proper care will extend the life of your POLVCDG X7 headset:

• Water Exposure: While IPX8 waterproof, avoid prolonged soaking in seawater or saltwater. After use in water, especially saltwater, rinse the headset with fresh water and wipe it dry immediately. Pay particular attention to the magnetic charging port to prevent corrosion from sweat or salt water.
• Storage: If not using the headset for an extended period, fully charge it at least once a month to maintain battery health.
• General Care: Keep the product away from fire, extreme heat, freezing temperatures, and harsh chemicals. Avoid violent impacts, disassembly, or squeezing the product.
• Charging Adapter: Always use a charging head with an output of 5V/1A or less. Do not use fast chargers.

7. User Tips

• Battery Life: The headset offers up to 10 hours of playback on a single charge (at 65% volume), making it suitable for long exercise sessions.
• Open-Ear Design: The bone conduction technology provides an open-ear listening experience, allowing you to remain aware of your surroundings while enjoying audio. This means it does not provide traditional sound isolation.
• Versatile Use: With its IPX8 waterproof rating and 32GB internal memory, the X7 is perfect for swimming, running, cycling, and other outdoor activities where carrying a phone might be inconvenient.

8. Troubleshooting

• Headset not powering on: Ensure the headset is fully charged. Press and hold the Power On/Mode Key for the specified duration (3-5 seconds).

• No sound in Bluetooth mode: Check if the headset is connected to your device. Ensure the volume on both the headset and your device is turned up.
• No sound in MP3 mode: Ensure the headset is switched to MP3 mode (double-click Power On/Mode Key). Verify that music files are correctly loaded onto the internal memory.
• Charging issues: Ensure the magnetic charging cable is correctly aligned and securely connected. Use a 5V/1A or lower power adapter. Clean the charging contacts if necessary.
