WARNING: Before continuing with this procedure, review the Warning and Caution statements listed
in the Warning and Caution Statements and General Safety Guidelines Section, Things You Should
Know.
The AMT utilizes a four flat belt system that provides support to the stairarms and allows fluid movement.
There are two outside flat belts and two inside flat belts. The two outside flat belts are routed from the
stairarm terminals, up over a flat belt pulley and through the upper arm, terminating at the upper arm cams.
The inside flat belts are routed from the platform through a series of pulleys, terminating at the upper arm
cams.
The flat belt system has a predetermined life span of 100,000,000 strides, which will be monitored through
the AMT's software. When the stride count reaches 90,000,000, a message will be displayed on the console,
warning that the flat belts will need to be replaced. If the belts have not been replaced by the time the stride
count has reached 100,000,000 and a stride count reset has not been issued through software diagnostics,
the AMT will lock out the display with an out of service, replace flat belts message.
The stride count odometer is now stored on both the upper PCA and Lower PCA. The dual memory locations
allow the stride count to be transferred in the event that an upper PCA or lower PCA is replaced. If the upper
PCA is replaced, the stride count stored on the lower PCA will be written to the new upper PCA. If the lower
PCA is replaced, the stride count stored on the upper PCA will be written to the new lower PCA.
Note: When the belts are replaced, it is required that all 4 flat belts be replaced at the same time.

Precor recommends not swapping lower and upper PCA boards to troubleshoot, but if swapping is the only
option to isolate a problem, swap only one PCA board at a time.
If you are swapping a PCA board to perform troubleshooting, note the process below to prevent the stride
count odometer from being prematurely overwritten.

When you stop pedaling the AMT, the AMT will pause for 20 seconds, and then give a 10 second
workout summary (which is when the records are written). After the PCA board is replaced and testing
the AMT is complete you will need to unplug the data cable within the 20 second pause period to prevent
