The M9.41S diagnostic program cycles through the following modes:

LED Mode. Illuminates each of the LEDs mounted on the upper PCA.

Lift Mode. Allows you to verify that the lift calibration number increments and decrements as the

INCLINE keys are pressed.

Power Bits Mode. Allows you to verify that the power bits number increments and decrements

as the SPEED keys are pressed.

Note:

When the treadmill is in power bits mode and the SPEED ▲ key is selected, the treadmill speed

will increase twice as fast as it does when the treadmill is in a normal operating mode.
