serial numbers starting with '1L' and were manufactured between January 24, 1995 and March

25, 1996. The M9.45 treadmill was then redesigned with serial numbers starting with '2P' and

were manufactured between March 26, 1996 and November 15, 1997. The 9.45i uses serial

numbers starting with ‘3Y’ and started in production on November 16, 1997. The 9.45i is the only

version of the 9.45 that is currently in production. This document will refer to the three versions

as follows 9.45 (1Y), 9.45 (2P) and 9.45i (3Y).

About The Smart Rate System

The Smart Rate system is the heart rate system mounted in the display housing. The Smart Rate

system receives a heart rate signal from chest strap transmitter worn by the user. Smart Rate

software displays a heart range on green, red and yellow LED's mounted on the upper PCA. The

LED’s indicate whether the heart rate is below, within or above the desired rang.

Procedure 2.1 - Accessing the M9.45 (1L or 2P) 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. On 9.45 (1Y & 2P units), with the PRECOR M9.45 banner scrolling, press and hold ENTER

until the software version number is displayed in the right display windows. On units that

have serial numbers starting with '2P', the part number of the PROM will also be displayed.

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. On 9.45 (1L units) the second routine is the lift test. The lift test takes the lift through each of

the critical lift positions. In doing so it tests the performance of the zero switch, upper limit

switch, lower limit switch and rotation sensor. Press ENTER to continue.

6. On 9.45 (2P) units 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.

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 that

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 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.

9. The fourth 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.

10. The fifth 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.

11. 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 and held 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.

Procedure 2.2 - Accessing the M9.45i (3Y) 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. For the purpose of accessing the various software routines, including the diagnostics

program, the display housing keys are hypothetically numbered 1 to 7 from left to right.

4. With the PRECOR M9.45 banner scrolling, press keys RESET,5,1,7,6,5,7,6,1, sequentially

(See Diagram 2.2).

5. 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..

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 that

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,

simultaneously to continue

9. 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.

10. 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.

11. 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.
