•
Shorten the distance between the heart rate chest
belt and watch.
•

WARNiNg
Signal interference in the environment can be
caused by electromagnetic disturbances. These 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. Under interference, the heart rate
reading may become unstable and inaccurate.
