CONDITION/PROBLEM THINGS TO CHECK SOLUTION
Electronics If all I/O cables are functioning properly, LED D indicates 
speed sensor is functioning, and err LS or OS persists 
problem is in either the upper electronics board or the 
motor controller board.  With machine on check LED A 
on the controller board. If it is dimly lit replace upper 
electronics (000-4430).  If it is not lit at all replace motor 
controller.

Size of steps taken In order for a step to register, the pedals must pass each 
other completely. This ensures that the magnet on the 
Step passes the step sensor. Make sure treadles are not 
locked in treadmill mode and that they are moving enough 
to register a step.
STEP SENSOR
1. Cycle power off and on. 
2. Put the machine in calibration mode (see Calibration 
procedures, Pg. 26) but do not start the calibration routine.
3. Remove right rear base plastic cover to allow access to 
LED board. Caution: Machine is on. Current is active!!
4. Locate LED C on the motor controller board.  LED may 
be lit or unlit.  
5. Manually manipulate the treadles up and down and 
check if LED C is blinking.
6. If LED C is not blinking, then the step sensor is 
not supplying a signal. Check that the step sensor is 
connected securely to P2 on the motor controller. If sensor 
is connected and LED C still does not flash replace sensor.
I/O CABLES
If LED C is flashing when the treadles are moved but 
steps are still not being counted check for signs of visible 
damage and connections to any of the three I/O calbes. If 
no visible damage check continuity using a multi-meter.  If 
a multi-meter is not available replace all three cables.
