2. What to do if the QX13 encounters issues?

Reset:

If abnormal software behavior occurs, reset by pressing the Menu + Volume Down buttons simultaneously.

Other error prompts may occur for the QX13:

1) If the display shows “Output Error”, the QX13 will stop output. Please disconnect the USB power and headphones, then reconnect them to try again.

2) If the display shows “Overheating”, it means the QX13 is overheating abnormally.

Please disconnect the USB and wait for it to cool down before using it again. In the meantime, it is suggested to enable the Desktop Mode in non-high-temperature environments.

3) If the display shows “Insufficient Power”, it means the current USB port cannot provide enough power, which limits the output power. Please use an external USB or the ESTICK power band for the power supply.

4) It may be a poor connection. Please disconnect the USB power and headphones, then reconnect them to try again.
