Table 6 may help you understand and troubleshoot erratic 
heart rate readings.

Note: To conduct electrical impulses from a user’s heart, the 
electrode strips on the chest strap must be in contact with 
the user’s skin. Usually, the concentration of salts in a 
person’s perspiration provides enough conductivity to 
transmit a signal to the receiver in the display console. 
However, because of body chemistry or erratic heartbeats, 
some people cannot use the heart rate feature.
