these are the hardware components of the kaypentax Phonatory aerodynamic system.we have the airflow tubes, they contain cotton in the inside.we have the large pressure tube attached to the kaypentax, hand held device,that is large tube,this little guy is intra oral tube,set up correctly it's gonna go inside large pressure tube also contains microphone,the end,when you're ready to use it you want to make sure that this plugged in over here you have the airflow head,when first getting the system these two items may not be attached so you do need to attach them together and then last we have the face mask setting this up for you.you're gonna make sure that you are correctly put together the airflow tubes,oh you're going to have this lower airflow tube closest to the airflow head top airflow tube talking to the side closest to the captor to the handheld device is going to face where you want to climb to set right through at large pressure tube .the intra oral tube can go right through the lower plug going to make sure that this owing here is secured against the screw right there the face mask you want to make sure that this intra oral tube through the face mask nice and snug making sure that this top part where the plug is on the top because that's how it's gonna fit nose.turn around you see that it's got that and engine here to face when you first entered the phonatory aerodynamic system it will bring you to this screen may ask you to calibrate the device.it doesn't make sure to do so going to be options menu calibrate airflow head a series of instructions attached the calibration syringe.the airflow head make sure you remove the intra oral tube if it's still in place attached to the handheld device on a table to prevent excessive movement to fully withdraw a plunger on the syringe motion that lasts between two and four seconds ,one way or syringe measures to be one point zero ,good.this system is calibrat.
