Note: 

Before connecting the power supply, please turn down 

            the volume control, bass control and treble control to the 
            lowest level (always to the left) to avoid your hearing 
            from damage.

Step 5: 

Toggle the power switch on the front panel upwards to 

               turn on this unit, and then short press the 
               multi-function knob (Volume Control/Mode Switch) to                
               select USB input mode, the input indicator light stays 
               white.

Note1: 

Short press the switch on the front panel upwards and 

              the input indicator light for a certain mode will 
              illuminate. 

Note2: 

There is a memory function to the mode, which means 

              after you turn on the power switch again, the K2 will 
              default to the mode you selected when you last ended 
              up using it, and the input indicator will show the 
              indicator color of the corresponding mode.

Note3: 

• Multi-function Knob: Volume Control/Mode Switch

              • Volume Control: Volume Control means turning the 
                volume control knob clockwise to adjust the volume 
                from low to high.
              • Mode Switch: Short press to switch input modes.
