Your machine was prescribed with a feature called FlexRx Exposure Limiting Software.  This feature allows your prescriber to keep track of how many treatments you have done, so they can follow up with your progress.

When your device shows the word “PASS”, it means that you have used up all of the prescribed treatments, and your prescriber just needs to order you a “refill” (similar to running out of a medication, and your doctor calls the pharmacy to order a refill). Once you notify your prescriber’s office that you have used all of your treatments, they should fill out our FlexRx Refill Request Form. As soon as we hear from your prescriber, we will call you with a brand-new, 4-digit number or “PASS” number.  You will enter the new number into your device, and it will automatically reset with the new allotment of treatments.
