ERROR MESSAGES

STARTRAC Displays Error Messages when the computer detects a malfunction. Please
record the Error Type AND Number displayed. This information, along with the definition of
Error Messages in the troubleshooting section, will tell the repair person what to do.

Error messages can be cleared only by switching off power to the treadmill.

CPU ERROR

If STARTRAC detects a fault in its internal operations it will stop and display "CPU Error 0 or
1 or 2" (Probably caused by turning the treadmill OFF and ON too quickly - the microprocessor
is not reset and also trips the circuit watchdog). Turn the power switchOFF, wait a couple of
seconds and then turn the power switch ON If the problem occurs again, contact Unison for assistance.

ELEVATION ERROR

If a problem develops with the elevation mechanism, "El Error 0, 1, 2 or 3" is displayed and the
treadmill stops.

Possible causes of this error include a stalled elevation motor, a defective elevation sensor or
cable, or a defective zero percent sensor or cable.

To allow operation of the treadmill until elevation can be serviced, depress the [0] key while
switching the machine on. In this mode, "EL-OFF' will appear for several seconds at power up
and no elevation operations will occur.

FAIL-SAFE ERROR

If the microprocessor detects the fail-safe (watchdog) circuit tripped on the motor control board
at the start or during a run, the display will show "FS Error O". Possible causes for this are cycling
power too fast (see CPU ERROR), defective motor control board or defective display cable.

SPEED ERROR

The display reads "SPEED Error 0, 1, or 2" when the microprocessor detects a problem with
the motor speed control.

THIS MAY SHOW AN UNSAFE CONDITION

Possible causes are a defective or misadjusted motor speed sensor / cable or motor control
board.
