2. Setup

- Connect to Audio Source: Connect the audio input cable from the subwoofer to the audio output jack (usually green) on your computer's sound card or laptop.

- Power On: Locate the power control knob on one of the satellite speakers (refer to Figure 1 for visual reference). Turn the knob clockwise to power on the system. The power indicator light should illuminate.
3. Operating Instructions
Once the system is set up, follow these instructions for operation:
- Power On/Off: Use the 'POWER' knob on the right satellite speaker to turn the system on or off.
- Adjusting Volume: Use the 'MAIN VOL' knob, also located on the right satellite speaker, to adjust the overall volume level. Turn clockwise to increase volume and counter-clockwise to decrease.

4. Maintenance
Proper maintenance ensures the longevity and optimal performance of your speaker system:
