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.
2.4.3. Use of Suunto X6
HR
and Transmitter Belt in water
Suunto X6
HR
is water-resistant to a depth of 100m/330ft. The transmitter belt is water-
resistant to 20m/66ft. To maintain water resistance and to ensure that the guarantee
remains valid, all servicing, exept for the battery change, should be performed by au-
thorized Suunto service personnel.
Heart rate measurement in water 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 temporarily short-circuited and the trans-
mitter unit cannot detect ECG (=electrocardiogram).
• Jumping into the water or strenuous muscle movement during competitive swim-
ming may cause water resistance that shifts the transmitter on the body to a location
where it cannot pick up the ECG signal.
• The ECG signal strength varies depending on the individual’s tissue composition.
People have more problems with heart rate measurement in water than elsewhere.
2.4.4. Activating the Heart rate monitor
To activate the heart rate monitor:
1. Attach the transmitter to the elastic strap.
2. Adjust the strap length to fit snugly and comfortably. Secure the strap around your
chest, below the chest muscles. Lock the buckle.
3. Raise the transmitter a little off your chest and wet the grooved electrode areas on
the backside. It is important that these electrodes are wet during the exercise.
