This is the small round UI Control Knob (Dial) that sits on top of all PR System One CPAP & BiPAP machines. The knob is used to control the machine's various settings and functions as well as to turn the machine on and off.

The System One UI Control Knob is dark, charcoal gray in color with a silver inlay around the rim. The sides of the knob are ridged to make them easy to grip.

COMPATIBILITY: This Control Knob comes standard with all "60 Series" System One CPAP & BiPAP machines -- REMstar Plus 260, REMstar Pro 460, REMstar Auto 560, BiPAP Pro 660, BiPAP Auto 760, etc. It can also be used to replace the lighter gray Control Knob found on all "50 Series" System One CPAP & BiPAP machines -- REMstar Plus 250, REMstar Pro 450, REMstar Auto 550, BiPAP Pro 650, BiPAP Auto 750, etc.

INSTALLATION: When an old UI Knob is removed or lost a small metal ring from inside of it can sometimes get stuck on your CPAP machine's knob post. If that ring is present the new UI Knob will not fit properly onto the post. To fit the new UI Knob properly remove the metal ring, either from the post or from inside the new knob, before inserting the new UI Knob onto the machine's knob post.

Directions would have helped
Written By: Matt, Allison Park, PA 9/7/2017
Got the part, on time and as expected. Looks just like the old one. Would have rated it a 5, except that I didn't get any installation instructions with the part. I did eventually find them online, and once I removed the nearly invisible portion of the old part, it worked fine.

Replacement knob
Written By: Sandy, Colorado 5/6/2017
The knob arrived very promptly as promised. It was what I needed but I am having difficulty attaching it permanently. It's just sitting on top loose.
