Setup Guide

1. Charging Your Earbuds

Before first use, fully charge your TONEMAC U8 earbuds. Use the provided USB-A to USB-C charging cable.

1. Connect the USB-C end of the cable to the charging port on the earbuds (usually located on one of the earbud bodies).
2. Connect the USB-A end to a USB power adapter (not included) or a computer's USB port.
3. The indicator light on the earbuds will show charging status (e.g., red for charging, blue/off for fully charged). A full charge takes approximately 1.5-2 hours.

2. Pairing with Your Device

The TONEMAC U8 earbuds use Bluetooth 5.3 for a stable connection.

1. Power On: Press and hold the Multi-Function Button (MFB) on the earbuds for 2-3 seconds until you hear a power-on prompt and the indicator light flashes (e.g., blue and red alternately), indicating pairing mode.
2. Activate Bluetooth: On your smartphone, tablet, or computer, go to the Bluetooth settings and ensure Bluetooth is enabled.
3. Select Device: Look for "TONEMAC U8" in the list of available devices and select it.
4. Confirm Connection: Once paired, you will hear a confirmation sound, and the indicator light will typically turn off or flash slowly blue.

Note: If pairing fails, turn off the earbuds and your device's Bluetooth, then repeat the steps. The earbuds will automatically try to reconnect to the last paired device when powered on.

Maintenance

• Cleaning: Regularly clean the earbuds, especially the ear tips and charging contacts, with a soft, dry, lint-free cloth. For ear tips, you can use a slightly damp cloth and mild soap, ensuring they are completely dry before reattaching.
• Storage: When not in use, store the earbuds in their portable carrying case to protect them from dust, dirt, and physical damage.
• Battery Care: To prolong battery life, avoid fully discharging the earbuds frequently. Charge them regularly, even if not used for extended periods. Store in a cool, dry place.
• Water Exposure: While IPX7 waterproof, avoid prolonged submersion in water. After exposure to sweat or rain, wipe the earbuds dry before charging.

Troubleshooting

Earbuds won't turn on:

Ensure the earbuds are fully charged. Connect them to the charging cable and check the indicator light.

Earbuds won't pair with my device:

Make sure Bluetooth is enabled on your device and the earbuds are in pairing mode (flashing red and blue). Turn off Bluetooth on your device, restart it, and try pairing again. Ensure no other devices are connected to the earbuds.

No sound or low volume:

Check the volume levels on both your earbuds and your connected device. Ensure the earbuds are properly seated in your ears and the ear tips provide a good seal. Try cleaning the ear tips and speaker mesh.

Connection is unstable or drops frequently:

Ensure you are within the 10m (33ft) Bluetooth range. Avoid obstacles between the earbuds and your device. Try disconnecting and re-pairing the earbuds. Reduce interference from other wireless devices.

Microphone not working during calls:

Ensure the earbuds are selected as the audio input device on your phone. Check if the microphone is muted (press Volume + and Volume - simultaneously). Clean any debris from the microphone opening.
