Manager Mode
After having used you Star Trac 4500 treadmill for several workouts, you may wish to specially
customize your treadmill by changing some of its settings.
To engage Manager Mode:
1. Press and hold the “ 0 ”, “ 1 ” & “ START ” keys together. While holding the “ 0 ” &
“ START ” keys down, release the “ 1 ” key only.
2. The display will beep and display Manager Mode momentarily, then UNITS will be displayed.
Once the treadmill is in Manager Mode, you may use the following keys:
INCLINE KEY: Displays the next or previous parameter.
SPEED KEYS: Allows the variable to be changed within the parameter.
ENTER KEY: Saves the value if changed in the EPROM (software).
Note: ENTER KEY must be pressed, for each value changed.
STOP KEY: Exists Manager Mode and restarts the treadmill with a “warm start.”
0 – 9 KEYS: Enters new parameter values. If UNITS parameter is displayed, key 5
starts DISPLAY TEST and key 8starts MOTOR TEST.
HEART HEART KEY: When pressed will automatically display manufactures default value.
Note: ENTER KEY must be pressed, to save the default values if changed.

Motor Test Mode
Motor Test Mode allows the treadmill to calibrate both elevation and running belt speed. Verifies RPM
Sensor feedback, Drive Motor and MCB response, and verifies Elevation Motor range (count). Also
burns in the motor, by way of the controls and displays of the treadmill.
***Caution*** : Do not stand on the running belt while performing these test.
Engage Test Mode:
1. Press and hold the “ 0 ”, “ 1 ” & “ START ” keys together (or the “0” , “2” ). While holding the “ 0 ”
& “ START ” keys down, release the “ 1 ” (or 2) key only. The display will beep and display
MANAGER (or MAINTENANCE) momentarily, then UNITS will be displayed.
2. Press and release the “8” key. Display will read: 240 3 .0 if treadmill is at 0%.
Alternative mode to enter Motor Test Mode:
1. Turn the power switch on while pressing the “ 8” key simultaneously on the display.
240 3 .0
A. Elevation Motor Range. B. PWM Duty Cycle. C. RPM Sensor Feedback
Once the treadmill is in TEST Mode, you may use the following keys:
INCLINE KEY: Adjust voltage to incline motor, inclines the treadmill in increments of 1%.
When using the Incline Keys verify the elevation system is responding correctly by the
following:
•As the treadmill elevates up and down verify the corresponding LEDs light up on the MCB.
•Verify that the Elevation Motor Range (see above A column) is changing in increments of
1% as the treadmill elevates up and down.
Caution:Do not elevate treadmill above 15% = 57 (110v units), 80 (220v units) or below
0% = 240 (110 & 220v units) mechanical damage may occur.
SPEED KEYS: Adjust the PWM duty cycle and motor speed up and down, respectively,
in increments of 0.1 mph (UNITS=English) or 0.1km/hr (UNITS = Metric).
When using the Speed Keys verify the speed control system is responding correctly by the
the following:
•As the treadmill begins to increase speed, verify that the display registers RPM feedback
(see above C column) in increments of 0.1 mph/km.
START KEY: Starts burn-in mode. (continuous operation of running belt and incline using
program 8 at maximum speed. Press STOP KEY to stop burn-in.
STOP KEY: Exists MOTOR TEST Mode and restarts the treadmill.
HEART KEY: Starts automatic calibration of minimum, 1/2 maximum, & maximum speed.
3.8

Calibration
***Caution*** : Do not stand on the running belt while performing these test.
Automatic Speed Calibration:
In this mode minimum and maximum speed is automatically calibrated. Calibration lasts less than 3
minutes; belt will be in motion during this test.
Auto-calibration should be done every time MN, MX SPD & UNITS parameters have been changed in
either SETTINGS or CONFIGURE Mode. Auto-calibration must be engaged when ever speed
controlling components have been upgraded or replaced such as; MCB, Display Board, Drive Motor &
RPM Sensor.
1. Press and hold the “ 0 ”, “ 1 ” & “ START ” keys together (or the “0” , “2” ). While holding the “ 0 ”
& “ START ” keys down, release the “ 1 ” (or 2) key. The display will beep and display MANAGER
(or MAINTENANCE) momentarily, then UNITS will be displayed.
2. Press and release the “8” key. Display will read: XXX 3 .0 if treadmill is at 0% display will read:
240 3 .0
3. Press “HEART” key, display will read: CAL treadmill will go into an automatic speed calibration for
less than 3 minutes. Press “STOP” key to exit Motor Test.
NOTE: If Auto-calibration fails to give the correct response refer to Section 4.
3.9

Display Test Mode
Display Test Mode allows you to test the light-emitting diodes (LEDs), 15-segment displays, and the
watchdog timer of the Display Control Panel by way of its own controls and displays. It also allows
EPROM version to be displayed. To enter Display Test Mode:
***Caution*** : Do not stand on the running belt while performing these test.
1. Press and hold the “ 0 ”, “ 1 ” & “ START ” keys together (or the “0” , “2” ). While holding the “ 0 ”
& “ START ” keys down, release the “ 1 ” (or 2) key.
2. The display will beep and display MANAGER (or MAINTENANCE) momentarily, then UNITS will
be
displayed.
3. Press and release the “5 key. Observe all the LEDs light up.
4. Pressing any key once will display the EPROM version.
Alternative mode to enter Motor Test Mode:
1. Turn the power switch on while pressing the “5” key simultaneously on the display. Observe all the
LEDs light up.
Once the treadmill is in Display Test Mode, you may use the following keys:
INCLINE KEYS: Lights % grade LED’s one at a time, also segments of 15-segment
screen one at a time.
PROGRAM SELECT KEY: Lights the six LEDs bordering the 15-segment display.
HEART KEY: Displays “HEART HEART” on the 15-segment display.
START KEY: Displays “START START” on the 15-segment display.
0 – 9 KEYS: Lights corresponding LEDs in the Number/Program Select Keys, (except
for key 9), alongside the Pre-Designed Program profiles.
STOP KEY: Displays “WD TEST” on the 15-segment display. Activates the watchdog
timer, resetting the processor and returning the program back to Start Mode.
