Check that magnets on both side of tension device has not fallen off
•
and without damages.

Problems with the sensors.
Technical advice how to check sensors of magnetic type:
1. Unplug the sensor on bikes circuit board.
2. In the jack in the end of sensor cable measure with a summer or an
ohmmeter then angle the magnet in near of the sensor. A signal should be
heard or value approx. 0 ohm displayed on ohm meter.
No heart rate displayed
Check the chestbelt (battery). Wet the thumbs and place them on the
•
electrodes. A low clicking sound will appear near battery lid while you
click on the electrodes with one thumb.
Check that the chestbelt is positioned correct on test person and tight
•
enough. Check that the electrodes are wet. In hard cases it is necessary
to use a contact gel or a mixture of water with a few drops of washing-
up liquid. The level for HR signal can vary from person to person. Put
chestbelt on another known person who has a good pulse rendering.
Uneven heart rate.
Use an external unit for example a HR watch to check if it also indicates
irregular pulse. If this is the case, there is probably disturbance in the room.
Magnetic fields from high voltage cables, elevators, fluorescent tube etc.
can cause the disturbance. Other electronic equipment could be placed too
close. Move the bike to a different location in the room or change rooms. If
an irregular HR remains it should be checked manually If the HR remains
irregular at work the person's health should be examined.
The weight basket moves up and down.
The brake belt contact surface may need to be ground off. See description
in section “Brake belt contact surface”.
The weight basket touch the flywheel.
The brake cord is probably not enough tightened. The basket can be loaded
with a lot of weight. Tighten the brake cord. See the section "Adjustment
brake cord tension".
According to test the bike seems to give
too high workload.
The brake cord may be too tighten. Loosen the cord according to section
“Adjustment brake cord tension”.
