nOTE To maintain the best performance of your chest belt, please handle it with care
according to the following:
according to the following:
• Do not wrap the chest belt in a wet towel nor with other wet materials.

TranSMiSSiOn SignaL
The heart rate chest belt and watch have a maximum transmission range of about 25 inches.
They are equipped with the latest digital coding system to reduce signal interference from the
environment, as well as analog technology.

1. The signal is weak - the watch may only show “0”:
• Shorten the distance between the heart rate chest belt and watch.
• Re-adjust the position of the heart rate chest belt.
• Check the conductive pads are moist enough to ensure solid contact.
• Check the batteries. If they are low or exhausted, the transmission range may be

• There is too much interference in the environment for your heart rate monitor to
function. Move to an area where the watch can register your heart rate reading.
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.
