A word about the SC-594 and Pulse estimation

The SC-594 is a simple detector meant to offer general guidance as to the Pulse Rate of a person at a given
moment in time. This is not a medical device and it should not be viewed as offering any sort of physical
indication, prescription, or protection. Each person makes their own decisions about their health and the
information they deem of value should be obtained from a licensed Medical Professional. Above all else, refer to
your Doctor or Health Care professional for guidance as to the exposure to exercise or day to day events which
are safe for you and your family.
The Pulse Rate is an indication of the number of times a heart beats during a period of time. We will estimate the
approximate number of times it will beat in a minute. Both internal and external factors can affect this rate,
including but not limited to Stress, Smoking, Exercise, Eating, rate of breathing, and Air Temperature. The SC-594
will have difficulty obtaining a Pulse Rate for those people having an irregular heart beat or cardiovascular deficits.
These calculations are for general reference and should not be considered as a diagnosis or any sort of medical
indication.
