Procedure 2.1 - Accessing the 9.25 Treadmill's Diagnostic
Program
Procedure
1. Plug the power cord into the wall outlet, then turn on the treadmill with the circuit breaker.
2. The diagnostic program provide six different routines to aid it testing and trouble diagnosis.
3. With the PRECOR M9.25 banner scrolling, press and hold ENTER until the software version
number is displayed in the right display windows.
4. The first routine is the LED display test. The routine will light every LED on the display as the
test proceeds. It is necessary to watch the display to see if an LED does not light.
5. The second routine is lift calibration. The lift calibration number indicates the physical
position of the lift. As lift is operated the lift calibration number will track the lift’s physical
position. The lift calibration number will be used to initialize the lift. Press the INCLINE keys
while you watch the right display window (see Diagram 2.1). The lift calibration number
increments as the INCLINE
▲ key is pressed and decrements as the INCLINE ▼ key is
pressed. Press ENTER to continue.
6. The third routine is the power bits display. Power bits is a number that indicates the amount
of time that power is applied to the drive motor (duty cycle). The power bit number reflects
changes in speed and load. Power bits and running belt speed will be displayed. Notice the
power bits number will increase or decrease as speed and/or load is increased or
decreased. The power bit number can be used to determine treadmill loading. Press
ENTER to continue.
7. The fourth routine is the keypad test. Seven dashed lines will appear on the display. Each
dash will correspond to a key on the display. Press each key one at a time, the
corresponding dash will enlargen, indicating the key that was pressed. Use this test to
determine if the keys are functioning properly. Press the INCLINE
▼ and SPEED ▲ keys,
simultaneously to continue.
8. The fifth routine is the safety key test. When the safety key is inserted SAFE ON is
displayed in the right display window. Remove the safety key from the upper display module
while you watch the right display window, SAFE OFF is displayed. Replace the safety key
and press ENTER to continue.
9. The sixth routine is the heart rate test. When a chest strap transmitter or test transmitter is
used, the heart rate will be displayed. Press ENTER to continue.
10. The last routine is the circuit breaker trip test. This test checks the ability of the treadmill to
trip the circuit breaker under software control. If the STOP key is pressed the trip signal will
be sent to the circuit breaker and the circuit will trip, shutting off the treadmill. If you do not
wish to trip the circuit breaker, press the ENTER key to exit the diagnostic program.

6. The second routine is lift calibration. The lift calibration number indicates the physical
position of the lift. As lift is operated the lift calibration number will track the lift’s physical
position. The lift calibration number will be used to initialize the lift. Press the INCLINE keys
while you watch the right display window (see Diagram 2.2). The lift calibration number
increments as the INCLINE
▲ key is pressed and decrements as the INCLINE ▼ key is
pressed. Press ENTER to continue.
7. The third routine is the power bits display. Power bits is a number that indicates the amount
of time that power is applied to the drive motor (duty cycle). The power bit number reflects
changes in speed and load. Power bits and running belt speed will be displayed. Notice the
power bits number will increase or decrease as speed and/or load is increased or
decreased. The power bit number can be used to determine treadmill loading. Press
ENTER to continue.
8. The fourth routine is the key pad test. Seven dashed lines will appear on the display. Each
dash will correspond to a key on the display. Press each key one at a time, the
corresponding dash will enlargen, indicating the key that was pressed. Use this test to
determine if the keys are functioning properly. Press the INCLINE
▼ and SPEED ▼ keys,
