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 chest belt 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 chest
belt 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.
