I just got one of the blue waves off of Ebay. i know it was used but not much.I have two questions about it. There are switches on the back of it. Is the first one the only one that should be in the on position. The other one is this light is loud, is this normal. I tink its the motor that turns the lights..Or is this supost to be real quiet??Thanks

Dip Switch one should be on for sound active mode. In regards to the sound the Wave can be slightly noisey do to the stepper motor.

Thank you for i insite of this light..I think you are right about how it sounds and it did take some figuring about the dip switches..being new to all this this forum really helps us new guys..
