10.1 Operation interferences
It is normally considered that about 70% of all shutdowns on small computers is caused by mains
interferences, i.e. at shot over voltage. These interferences can often be caused by different machinery,
which is stared or stopped. The processor in the computer is then reacting incorrectly or is not wor-
king at all. The problems can be solved by means of a mains interference protector, which is connected
between the mains and the transformer.
10.2 Trouble shooting guide
Symptom Probable Cause/Corrective Action
The Display is not working. Check that transformer is plugged into proper voltage AC
outlet and that the power connector is plugged into the
839 controller.
Display lights up but does not respond
to keyboard. Turn off power, wait 10 seconds and reapply power.
Does not load work Check RPM ( no force is applied if RPM is less than the
pedal low ref.. Default 30 RPM)
Check calibration
No heart rate Check the chest belt (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.
Use another external HR monitor to check the belt.
Check that the chest belt is positioned correct on test per-
son and tight enough.
Check that the electrodes are wet, in hard cases it is neces-
sary 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.
Check for no loose cables or jack if you have a plug-in re-
ceiver. Use another pulse receiver (pulse watch or test bike
monitor) to check the chest belt.
Check that it’s the correct receiver and that it is placed
correct. If it has a round Polar-sticker it should be placed
straight.
No RPM reading Check cable.
