Heart rate measurement in a water environment is technically demanding for the following reasons:
• Pool water with a high chlorine content and seawater may be very conductive and the electrodes of the
transmitter may get short circuited and ECG (ECG = electrocardiogram) signals cannot be detected by the
transmitter unit.
• Jumping into the water or strenuous muscle movement during competitive swimming may cause water
resistance that 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.
