X. Troubleshooting:
1. The device cannot be powered on by pressing Power On button. Please charge it and
confirm whether the batteries are full.
2. The computer or mobile phone cannot be connected to the Bluetooth headset normally.
Please follow the correct pairing operations and check whether the device to be paired
has enabled the Bluetooth function.

red and blue indicator lamps are flashing alternately).
2) If the Bluetooth headset is powered on but still cannot be located, please restart the

are connected
1) The Bluetooth headset is running out of power. Please charge it as soon as

Headset, which leads to shorter receiving distance that results in noises or
disconnection. In addition, muffling the Bluetooth headset with hands will also result
in disconnection.

the headset icon below, and then click OK.
3) Some mobile phones do not have complete stereo Bluetooth module, hence
no function of listening to music through Bluetooth device. You can connect the
