 Okay, so here is the aseptical unit that I have, and I do have two handspeed hookups for it. But I'm going to show you how to get your slow speed to work on the aseptic. So for starters, what a lot of people don't think is make sure on the bottom. This is towards the F. Sorry, I can't get it to focus right now, but F and not R. If it's towards the R, then quite often your, your proficup won't spin. So make sure this little, I guess, toggle or whatever you want to call it is towards the F. Okay, so I'm going to put that back. This is how I have it for the slow speed handpiece. So if you look on the side units here, you'll see, sorry, all the cords here, you'll see handpiece, there's one on this side, but I also have one on the other side as well because I have a slow speed and a high speed hookup. This one is for the slow speed, depending on what system you have, it might be on either side, but on and off. So the switch is towards on this one here, it's towards low. Since I'm using a low speed or a slow speed handpiece, if it was turned this way, your, your, your slow speed wouldn't work. So you need to make sure that's for low if you have this function and make sure this is pushed on, but you also might have to play with this one down here. If the motor's working, but nothing spinning, you might have to adjust both of these. Okay, so see how there's different toggles again. You might have to adjust this one. So I suggest playing with it and really try, but then if you notice I have another one for high speed. I don't want the high speed, so that's why I haven't really played with this one too much. Sorry, that would be this one here. So you might have to play with a couple things, but the main thing is make sure this is switched to low. Switch to on and you will have to play around with your slow speed, like moving it back and forth so that way you get enough pressure through. So I hope that helps. I have lots of different hookups here, but that is specific to the slow speed. Good luck and let me know if any questions.
