2.4. HEART RATE MONITOR AND TRANSMITTER BELT
The heart rate monitor is the premier feature of Suunto X6hr. It provides you with a
versatile instrument for measuring and analyzing physical performance in different
conditions. When used in conjunction with the altimeter function, the heart rate
monitor allows you to observe changes in heart rate during ascents and descents and
the impact of altitude on heart rate. The heart rates can be recorded in Suunto X6hr
memory and transferred to a PC for analysis. The heart rate data is available in Hiking
and Chrono modes.
2.4.1. 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.
It is best to position the Wristop computer within 3 feet (0,9 meters) of the transmitter.
Ensure that no other transmitters are within that range; signals from other transmitter(s)
can cause an incorrect readout.
Repeated kinetic shock to the Suunto X6hr may cause an incorrect heart rate readout
and should be avoided.
2.4.2. 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 recommend an exercise test under a doctor’s supervision. This will
ensure the safety and reliability of the pacemaker and the heart rate monitor when
used simultaneously.
