shifts the transmitter on the body to a location where it is not possible to pick up the ECG signal.
• The ECG signal strength varies depending on the individual’s tissue composition and the percentage of people who
have problems with heart rate measurement is considerably higher in a water environment than in other use.
Note: The Wristop Computer is not a dive instrument, and therefore buttons should not be operated (put to use) while
under water.
2.2 SUUNTO WRISTOP COMPUTER AND INTERFERENCE
ELECTROMAGNETIC INTERFERENCE
Disturbances may occur near high voltage power lines, traffic lights, overhead lines of electric railways, electric bus lines
or trams, televisions, car motors, bike computers, some motor driven exercise equipment, cellular phones or when you
walk through electric security gates.
Electromagnetic interference may cause inaccuracy in receiving heart rate signals. The sum of the “above”, “below” and
“in” heart rate values may be shorter than the total elapsed time. The reason for this inaccuracy is that the electromagnetic
interference may prevent the Wristop Computer from receiving signals of the transmitter belt perfectly.
2.3 WARNINGS
• Persons who have a pacemaker, defibrillator or other implanted electronic device use the Heart Rate Monitor at their
own risk. Before starting the initial use of the Heart Rate Monitor, we highly recommend an exercise test under a
doctor’s supervision. This will ensure the safety and reliability of the pacemaker and Heart Rate Monitor when
simultaneously being used.
• Exercise may include some risk, especially for those who have been sedentary. We strongly advise consulting your
doctor prior to beginning a regular exercise program.
• Disturbances may occur near high voltage power lines, televisions, cars, bike computers, motor driven exercise
equipment or cell phones.
• It is best to position the Wristop Computer within 3 feet or 1 meter of the transmitter. Ensure no other transmitters are
within that range; signals from another transmitter(s) can cause an incorrect readout.
