VII. Common Function Description
Power-on Status: Press the Power Button to turn the speaker on and it beeps simultaneously with the blue indicator
flashing. The volume is set to 60% by default.
Bluetooth Connection: Once switched on, the speaker starts searching for other Bluetooth devices automatically and at
the same time, the blue indicator goes on and off. When a Bluetooth device is found, the
speaker prompts whether to pair up or not. Select yes, QBT-340 will pair up with the device, the
blue indicator flashes slowly and a beep is generated by the speaker. If paring fails to detect any

to search again. All the paired devices will engage in automatic connection when the speaker is
turned on.
