Operation Instructions
Power On & Pairing
- Boot Up: In any state (except for power failure of the charging box), turn on the headset by taking it out of the charging box (one button power on, pairing, and back connection).
- Pairing (from off state): When the machine is turned off, long press the multi-function key (one key startup, pairing, and back connection).
- Pairing (alternative): In the off state, press and hold the multi-function key until the white and blue lights flash alternately (one key startup, pairing, and back connection).
- Connecting to Phone: After pairing, choose to connect to the Bluetooth headset from your mobile phone.
- Initial Setup: Turn on the charging box and take out the two Bluetooth headsets. They will flash. After 3-10 seconds, one headset will flash white and blue alternately, and the other will flash blue slowly. Then, enable Bluetooth on your device, search for the headset, and connect. If issues arise, clear the mobile phone's Bluetooth list and repeat the process.
- Subsequent Use: Once paired, turning on two Bluetooth devices will automatically connect them back to the mobile phone.
Controls
- Answer Call: Press the multifunction key once during a call.
- Hang Up Call: Press the multifunction key once during a call.
- Refuse Call: When calling, press and hold the multifunction key until the call is hung up.
- Pause/Play Music: Single click the multifunction key.
- Next Song: Double-click the multifunction key.
- Last Song: Triple-click the multifunction key.
- Shutdown: Place the headset back into the charging box and close the cover. The headset will turn off and charge (indicated by a white light).
- Shutdown (alternative): In standby mode, long press the multifunction key until the white light flashes.
Disconnection
The headset disconnects if it is more than 10 meters away from the mobile phone, or if the mobile phone actively disconnects the Bluetooth headset. The indicator lights will flash red and blue alternately.
Low Battery
A voice prompt indicates a low battery.
Charging
Close the top cover of the charging box to charge the headset. While charging, the Bluetooth remains active for a period. The charging box enters sleep mode after 30 seconds.
Charging current: 35mA
Power Display
Apple and Xiaomi mobile phones support the display of the Bluetooth headset's battery level on the phone's interface.
Main and Auxiliary Machine Separation
If one Bluetooth headset is placed back into the charging box, the other headset will remain connected.
Clear Headset Pairing List
When the Bluetooth headset is not connected to any device (mobile phone or TWS), perform a fast 3-click on the multifunction key to clear the pairing list.
Charging Attention
When charging the headphones, ensure the charging box cover is closed. If there is poor contact due to oil contamination on the headphones or spring pins, check if the two headphones show a white light when the charging box is half-closed, or if the Bluetooth icon on the mobile phone is disconnected. If these indicators are not as expected, the Bluetooth headphones may need replacement.
