2.4.7. Secondary Safety Warnings; Ultrasound

few primary warnings regarding, first of all, eyes and secondly, cardiostimulators. So keep these two primary warnings in mind at all times. Other secondary warnings are more of the getting the best results. Like one example is ultrasound. So when you will flip through the user guide, you will see frequently that when you treat the head, you need to which ultrasound off. But from experience, we know that ultrasound cannot and will not damage the neurons in the brain. The ultrasound used in chemotherapy is very low power. And this is more of a general precaution that I had to put in the user guide. When in actual effect, what we have found out so far is that using ultrasound on the head is actually accelerating results. So there are other safety warnings in the user guide, but again, I would urge you to study this module in detail, and it's about 20 minutes long, and you can again click through the slides to learn on the dose safety warnings and what they mean and so on.
