3. Alternator

No start When no one exercises on

the machine, the display

does not light.

1. Inspect the battery fuse on the drive board.

2. Measure battery voltage. Normal: >5.5V.

3. If battery voltage is lower than 5.5V, exercise

on the unit at 50 RPM or higher to recharge

the battery.

4. If battery voltage is lower than 2.0 and will not

recharge, discard it.

No resistance During exercise, you press

resistance keys; resistance

settings change on the

display; but there is no

resistance.

1. Inspect all cable connections.

2. Inspect reed switch operation.

3. Inspect alternator function: If unit will not start

via the alternator, there will be no resistance.

4. Inspect the electro-magnet and its cable

connections.

5. Inspect whether the drive board emits voltage

to the magnet.

malfunction

1. Inspect the heart rate transmitter strap and its

battery. Replace the battery if it has been used

for a long time.

2. Inspect the heart rate receiver cable

connection.

1. Test or replace the heart rate receiver board.

2. Inspect the environment for interference

from speakers, lights, etc.

Excessive resistance

Exercise on the unit; there

is excessive resistance.

1. Inspect all cable connections.

2. Rotate the flywheel. Inspect whether the

electro-magnet is stuck on the flywheel.

3. Inspect whether a drive board component

short is creating excessive output to the

electro-magnet.

1. Drive board

How to show total

distance

1. Press and hold workout

level<▲>+<▼>+<stop> for three seconds.

Total distance will appear.

Battery won’t

recharge

Exercise on the unit; the

battery does not recharge.

1. Measure battery voltage. If voltage is below

2.5V and battery will not recharge, replace

the battery.

2. Inspect the drive board fuse.

3. To recharge the battery, exercise intensity

must be over 40 strides/minute.

4. Inspect whether the battery recharge

indicator LED on the drive board lights. If

not, the drive board is bad.
