5.2 THE CONSOLE DOES NOT LIGHT UP.
SYMPTOM:
Turn on the power switch, but the console will not light up.
(Oxford 6) SOLUTION:
The outlet of the machine is plugged and is functional. Double check that the breaker has not
tripped.
The correct power cord is being used. Only use the power cord included. Test the voltage on
the power cord to verify it provides the specified output voltage listed on the label.
The power cord is not pinched or damaged and is properly plugged into the outlet and the
machine.
Unplug power cord. Remove the console and check that all connections to the console are
secure and not damaged or pinched. Unplug and reconnect the console cable to avoid poor
connection.
(Oxford 3) SOLUTION:
Remove the back batteries cover and check to see if the battery placement is good
Change the console batteries.

CHAPTER 5:TROUBLESHOOTING
5.4 HEART RATE ISSUE
Symptom:
Heart rate does not work.
Solution:
Check the battery on the chest strap.
A. Re-center the strap on the user's chest (Figure A). Apply a light amount of moisture to
the chest strap sensors.
B. Replace the chest strap.
With a multi-meter set for ohms, measure the resistance of the heart rate receiver wire.
Replace the wire if no resistance is found (1000412131+1000411433).
If the receiver wire checks good, or replacing the wire does not resolve the issue, replace the
console connected wire (1000411432).
If replacing the receiver wire, console connection wire does not solve the issue, replace the
console (1000428840).

CHAPTER 5:TROUBLESHOOTING
5.5 RESISTANCE ISSUE
Symptom:
No resistance or incorrect resistance
Solution:
1. Turn on the console and check the ECB motor (1000213379)/tension control (1000412305).
At resistance level 1, the head of steel rope directs to top right side (around 45 degree).
If the head of steel rope points to bottom left side, the resistance will be reverse. Adjust the head of steel
rope to the correct position.
Notes: in the lowest resistance level, the cable should have no tension.
2. Use knob to adjust the resistance.
A) If ECB motor/tension control cannot move, the resistance will not be changed. The ECB motor
or console cable is defective. Check the console cable inserted in ECB motor. Re-connect the console
cable first, if still not working, test cable for damage. If tests good, replace the ECB motor, make sure
both cable ends are seated properly.

CHAPTER 5:TROUBLESHOOTING
5.5 RESISTANCE ISSUE
B) If the ECB motor/tension control can move, the resistance can be adjusted. If the resistance is
still too heavy, check the gap between orange block and the bottom. It should be within 1-2 mm.
If the gap is larger than 1-2 mm, the resistance will be heavier than normal. Adjust the cable to the correct
gap range.
3. If all above conditions are OK, and the resistance is still too heavy, inside magnet is defective. Replace
the ECB controller (056539-AX).
