[. . . ] Warnings Persons who have a pacemaker, defibrillator, or other implanted electronic device use the heart rate monitor at their own risk and it is recommended they undergo an exercise test under a doctor's supervision before using the heart rate monitor for the first time. This will ensure the safety and reliability of the pacemaker and heart rate moni14 tor when being used simultaneously. Exercise may include some risk, especially for those who have been sedentary. We strongly advise you to consult your doctor prior to beginning a regular exercise program. 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 other transmitter(s) can cause an incorrect readout. Repeated kinetic shock to the Suunto OBSERVER ST may cause an incorrect heart rate readout, and should be avoided. The Suunto OBSERVER ST and transmitter belt usage in water 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 short-circuited; the transmitter unit cannot detect the ECG (electrocardiogram) signals. · Jumping into the water or strenuous muscle movement during swimming 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. 15 3. Set the correct month (1-12) with the arrow buttons and short press SET. Set the correct year (the years 01-49 on the display mean 2001-2049) with the arrow buttons and short press SET. Heart rate Heart rate is one of the three shortcuts that can be seen on the bottom row of the Time mode's main display. When it is visible, you can access its functions by long pressing SET. HR Limits This setting determines whether the HR limit alarm is active or not. The alarm informs you when your heart rate goes outside the upper or lower HR limit. Two different sounds are used to inform whether it is outside the upper or the lower limit. The HR value also starts to flash on the main display when the alarm is activated. If Al tone is set off (see page 24) and HR Limits On, the Suunto OBSERVER ST only flashes the HR digits. The state of the set HR limits on the middle row of the display is activated. Set Limits This selection determines the upper and lower Heart rate limits.
