COMPUTER TROUBLE SHOOTING GUIDE

POSSIBLE CAUSE
Refer to the Assembly Instructions and verify all the Wire Plugs are
connected FIRMLY and correctly.
Check Magnetic System(25) and Control Motor(29). The motor should
be able to adjust the resistance of Magnetic System freely. If the Motor
makes abnormal sounds and struggles to adjust the resistance, try to
locate and correct the problem in the Magnetic System. It may be
necessary to replace the Magnetic System. After correcting the problem,
verify that the motor works correctly.
If an unusually loud noise come from the Motor, it means gears in the
motor gearbox do not mesh correctly. Reverse to adjust the resistance,
and try again. If this fails, replace the Motor.
lf the Motor does not move at all, reverse to adjust the resistance, and
try again. If this fails, replace the Motor.
Disconnect the Adaptor. Reconnect the Adaptor to REBOOT the system.
Wait two minutes then verify that the system works correctly.
Remove and reinsert the IC Chip. If reinsertion fails, replace the
Computer.
Verify that the correct Adaptor is used.
Check that the Adaptor is correctly connected to an electrical outlet and
plugged into the socket on the machine correctly.
Replace the Computer.
Verify that the Sensor Magnet(31) is installed correctlly and passes in
front of the Speed Sensor.
Verify the gap between Speed Sensor and the Magnet is 5mm or less.
Verify all the Connection Wires(32, 35) are connected FIRMLY and correctly.
Verify that the Connection Wires(32, 35) are not damaged.
If all the above checks fail, then replace the Speed Sensor(32).
Replace the Computer.
Verify that the Circuit Board is securely fastened to the Computer Case.
Retighten the Screws. Take care NOT to over tighten the Screws as this
may destroy the Circuit Board. You just need to keep the Circuit Board
firm, STOP tightening screws when you meet resistance.
Open the Computer Case. Remove the Circuit Board Screws, gently
remove the Circuit Board. Realign the LCD Screen and the Rubber
Membrane. Reassemble the Circuit Board taking care not to bump or
knock the Rubber Membrane out of alignment before the Circuit Board
Screws are tight. You just need to keep the Circuit Board firm, STOP
tightening screws when you meet resistance.
Replace the Computer.
Verify that the Pulse Sensor Wires(37) are connected FIRMLY and
correctly.
The Hand Pulse Sensors will NOT operate correctly if your skin is
extremely dry. Moisten your hands with a little water and try again.
Grasp the Hand Pulse Sensors firmly and avoid moving your hands while
exercising. The computer will need a few seconds to detect and display
your correct pulse rate. If this does not work, try relaxing your grip on the
Hand Pulse Sensors.
Clean the Hand Pulse Sensors to ensure a good contact between your
body and the Pulse Sensors.
Remove the Hand Pulse Sensors and verify that the spade terminals
are correctly attached.
If the problem still exists, replace the Hand Pulse Sensors.
Replace the Computer.
