LED Functions
LEDs are used to indicate the status of many of the treadmill inputs. After entering Test Mode refer to the
following list to check that these LEDs are functioning properly:
Heart LED – Blinks on with every signal from the contact heart rate receiver.
Weight LED – Blinks on when CSAFE data is being received.
Level LED – Blinks on when CSAFE data is being transmitted.
Lower Left Window – The numbers indicate actual elevation. A '-' sign indicates the treadmill is below
0% grade. The decimal point before the numbers shows the activation of the 0% switch in the elevation
motor (on above 0%). If dashes are shown in the display, the treadmill is either above or below the 0%
switch, requiring it to be manually run through the switch to begin indicating actual elevation. The right
most decimal point indicates the status of the E-stop relay, on when the E-stop relay is on, off when it
is deactivated. NOTE: The right most decimal point may be difficult to see. Lean your head to the left
to see this.
Lower Right Window – The numbers indicate actual belt speed. The right most decimal point indicates
the pulses from the speed sensor on the motor.
Key Functions
While in Test Mode press the following keys for desired information:
Quick Start – Starts the belt at 1.0 mph (1.0 kph). Also will run calibration if held for 3 seconds.
Heart Rate Program key – Lights all of the LEDs for a short period of time.
Weight Loss key – Lights only the columns.

Distance – Press once for odometer information (DST) to appear in the speed window.
Press again for hourmeter information (HRS) to appear in the speed window.
Press three times for number of starts information (USES) to appear in the speed window.
Press four times for brush wear mileage up to 100 miles since activated or “0” if it has not been
activated (BRSH).
Min Mi/Km – Displays and cycles through error log. Up to 10 errors can be stored.
Scan – Clears error log when pressed twice while in error log mode.
Mets – Value of motor load inA/D counts. The number range is relative to motor current and goes
from 0-225. (LOAD).
Calories – Displays motor pulse width (PWM) value.
Enter – Required to save setup values.

Error Codes
Error codes notify you of a problem condition and are displayed on the center of 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.
A log of errors can be viewed and cleared. Enter Test Mode and press the Pace (Min/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 Stop to
exit Test Mode.
NOTE: A processor upset can cause a bAd#. See H then G.

Err1 Belt didn't start (or no speed sense). See I, E, D, B then A.
Err2 Underspeed (2 mph for 2 seconds without correction in process). See I, E, C then B.
Err3 Speed sense lost. See I, E, A, B and C.
Err5 No 0 switch sense within timed limits. This is declared when the timed
elevation reaches -2% without tripping the index. See F and A.
Err6 Overspeed (1 mph for 1 second or 2 mph for 0.2 seconds without
correction). See I, E.
Err7 EEPROM error (memory lost, loads new defaults, enters Test Mode). See G.
Err9 Brush wear too low. Indicator has been activated for over 100 miles. See D.
ErrE 0% always on (or switch disconnected or wired backwards). This means
that timed elevation has gone up 2% and the index is still sensed. See F.
