Maintenance
Reading the Active Status Light
The active status light is located at the front edge of the
treadmill hood, as shown in the following figure. The light is
large enough and bright enough to allow you to check the
condition of all your treadmills at a distance.
Figure 34: Status light location
During normal operation, the status light is a steady blue. It
changes color and pattern if the treadmill's electronic drive
unit detects a mechanical or electrical problem.
