Accessing the Diagnostic Program
The 9.23 Treadmill's diagnostic program cycles through the following modes:
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 view the power bits value displayed on the display console.
Safety Key Mode - Allows you to verify that the message on the right display window cycles from SAFE ON to SAFE OFF when the safety key is removed from the upper display module.
Heart Rate Mode - Allows you to verify heart rate monitor operation.
Circuit Breaker Mode - Allows you to verify that the circuit breaker trips when STOP is pressed.
