Assigning heart rate sensors
Heart rate sensors can be assigned when the course is created or afterwards. An ongoing or future heart rate course can be edited at any time.
- Go to Courses.
 - Find the course on the Ongoing courses list, or use the search.
 - Click the row or the  icon 
 to open the course. - Click Edit course.
 - Click Assign sensors.
 - The system  assigns  a sensor for each student automatically. The number of the assigned sensor  is shown for each student. You can use the drop-down list to reassign the heart rate sensors manually.
 - Click Save to accept the reservations. The software redirects you back to the course information page.
 
If a student has purchased their own heart rate sensor to use instead of a school sensor, you need to register the sensor ID to the system. If a student has a personal heart rate sensor in use, the system does not assign a school sensor for that particular student.
Within a course, one sensor can be assigned to one student at a time. Within a school, one sensor can be assigned to several students at a time provided that they are not participating in the same course. Individual students can take several heart rate courses simultaneously, and have several heart rate sensors assigned to them.
                                            
 If a sensor is lost or broken, a teacher can assign a new sensor to a student in the Polar GoFit app right before the PE lesson.
