6. Solució De Problemes

Consulteu la taula següent per veure els problemes habituals i les seves solucions:

Fenomen	Solució
No es pot activar	Check the power adapter. Only connect the power adapter to a power outlet, not to the unit. If the LED on the adapter blinks or does not light up, the adapter is defective. Comproveu la connexió d'alimentació.
Sense so	The device did not power on. Check LED and the power connection. Check that the proper input source is selected. Press the knob to switch input channel. Check that the proper output channel is selected. Double-press the knob to switch output channel. Comproveu les connexions de tots els dispositius. Inseriu els cables de connexió fins al final. Check the volume of all devices and whether they are muted. Bluetooth IN: Too low volume on phone. Please adjust volume. ENTRADA USB: 1) Too low volume on PC. Please check and adjust the computer system volume, music player volume and driver volume. 2) Select the default output device of your music player or computer as this unit.
So anormal	One channel's positive output and negative output may be reversed, please check and correct it. The cables may not be connected correctly, check and reconnect them. Probably overloaded. Try turning down the volume. May be caused by high temperature. Turn the power off, wait for the unit to cool down sufficiently, and then turn the power on again. Please place the unit in a place having good ventilation. Check to see if the problem is with the source, downstream equipment and cables.
One channel with noise/no output	Check to see if the problem is with the source, downstream equipment and cables. You can try swapping the left and right channel connections.
