1. Connect the AC adapter, and turn on the power of the main unit.

2. Obtain the manual training program, set the pedal torque setting to 4.0kg·m, and rotate the pedal at the rate of 50 rpm. If you can rotate it quite easily, no load will be applied.

3. Replace the control unit with a brand new one.

4. Again, check the torque status under the manual training
program.

1. Turn off the power, and loosen the four screws on the
handlebar stem to remove the control unit. (Fig. 1)

2. Remove the cable connector which is connected to the back of the control unit. (Fig. 1)

3. Remove the frame cover. (See the Sections D1 & D2 "Removing the Frame Covers.")

4. Remove the CN-2 connector on the power supply board. (Fig. 2)

5. Using a tester, check for any short-circuiting across Terminal
1s and Terminal 4s at both ends of the 5P cable which
connects the power supply board and the control unit. (Fig. 3)		Connector	CN-1 Connector
