If you're using our Predictive Fatigue Monitoring Solution and the Bluetooth-enabled Readiband 4, go here for all the latest help articles.
There are two reasons why a Readiband will display six horizontal dashes followed by scrolling text reading "NOT READY" :
The recording session hasn't started yet (the Readiband was initialized with either Manual start or Start at a specific date and time)
The recording session started less than 30 minutes ago. Once approximately 30 minutes has passed, the Readiband will display a real-time effectiveness score.
Note: It takes 72 hours for the Readiband algorithms to accurately calculate the wearer's real-time effectiveness score when you first start wearing the band.
