This manual begins with important safety information, warning users about proper placement, avoiding moisture, and using only the supplied accessories. It also outlines the steps for connecting the speaker to a computer or audio source and explains the function of each control button.
The second part lists the technical specifications such as power output, sensitivity, input impedance and dimensions, followed by a troubleshooting section that addresses common issues like water exposure, mono playback from CDs, and distortion when using the USB input at high volume. This manual is written in Chinese.
First check that all connections are correct and then verify the audio source; if the connections and source are fine, the speaker should work normally.
