Can someone tell me how high or in which frame the spg. for the lambda sound must be?? and how do I measure the?? so turn off or on and off and just get up or how do I do that??? why I come up with that is quite simple, so I have the problem that my little one in the stand is running very restless and then my works said that I should measure the lambdaspaanunnng. I would repent. please if goes to the end of the week, then I have to get to the cart anyway and I’ll check it out.
