Error Codes

Error codes notify you of a problem condition and are displayed on the console. These codes
can also help to indicate the part of the treadmill most likely to be causing the problem. Errors
that present a hazard to the user provide a measure of safety by causing a one second beep,
stopping the treadmill and locking out operation of the treadmill. Reset power by unplugging
unit for a few seconds, then plug power cord into outlet.
A log of errors can be viewed and cleared. Enter Test Mode and press the Pace (min/mi/km)
key to display the log. The most recent error is always first in the log. Press the Pace key
again to cycle to the next the error stored. Up to 10 errors can be stored. Press the Scan key
twice to clear the error log. Press Pause/Stop to exit Test Mode.
