Volume Adjustment: Rotate the knob clockwise to increase volume, counterclockwise to decrease.
Source Selection: The system automatically plays audio from the "Audio In" (primary) jack. If you connect a cable to the "Aux In" jack, it may take priority or require you to pause the primary source.
Using Headphones: Plugging in headphones automatically mutes the speakers. Unplug to resume speaker sound.

WARNING! Avoid setting the volume to maximum for extended periods to prevent distortion and hearing damage.
