A:
The instructions are limited, but the illustrations get the point across. The left inside flap of the box, that the speaker system came packed in, has a 3 step illustration, that will guide you through the assembly. Look at the back of the woofer, and steps 1 & 2 to orient yourself, to where everything is plugged into. Then press the timer button. The green light should illuminate, then slowly rotate the thumb wheel, on the semi-circular shaped speaker control, to your desired sound level. I have a separate headset, that has it's own volume control, that I plug into the bottom of the speaker control, for private listening. I attached a picture of the inside flap, in case you don't have the box.
Good luck !
