3. When the LED at the front of the woofer speaker flickers in green and red in turns, remove the power cords of the main body and the woofer speaker from the power outlet.
4. After a moment, make sure that the LEDs of the main body and the woofer speaker are completely turned off, and wait for about a minute and connect the power cord of the main body and the woofer speaker.
