FREQUENTLY ASKED QUESTIONS
Q. I can’t get a heart rate reading, what’s wrong?
a. Check the battery in the heart rate transmitter. The battery should last approximately 700
hours or one year during regular use.
b. Make sure that the transmitter is being worn properly and that the electrodes are properly
moistened with saliva or conductive gel.
c. Have you had a cardiac event that has altered your pulse waveform? This may cause the
unit to not be able to identify a heart rate signal—CONSULT YOUR CARDIOLOGIST.
d. Make sure that you are clear of any sources of electromagnetic inference (i.e. TV sets, home
security systems, exercise equipment, etc.)
Q. The display on the watch unit is blank
a. Usually this means that the watch battery is dead and needs to be replaced. Have this serv-
ice done by a qualified watch technician.
Q. The calories number that I get during exercise seems high
a. Make sure that you are entering your weight in the proper units. If the watch is set for 24-
hour mode your weight must be entered in kilograms. If you enter your weight in pounds
while the watch is in 24-hour mode your calorie readout will be over 2x too high.
b. The calories calculator is designed to estimate the number of calories consumed for an aver-
age person at average exercise levels. It is only an estimate and may not accurately calcu-
late if the unit is being worn at heart rates less than 110-120 beats per minute. Caloric
consumption is highly variable between individuals and the number indicated by the unit
should only be used as a comparative indication of work performed during your workouts.
