USING THE HEART RATE FUNCTION
Chest Belt Heart Rate Sensor
The chest belt heart rate sensor is based on the electrocardiograph methodology used in hospi-
tals. The MSC-2Dx uses this technology but in a simplified and miniaturized form. In this meth-
odology, electrodes attached to the body sense the differences of electric potential and thus
heart rate is measured. In the same manner, MSC-2Dx's chest belt sensor uses two built-in
electrodes that come into contact with the body to detect differences in electric potential. The
signal is then transmitted to the main unit and heart rate is displayed.
Reference:
Maximum transmitting distance: about 90 cm.
Before Wearing Chest Belt Heart Rate Sensor
Warning !!!
Pace maker users should never use this device.
NOTE !:
• Wear the chest belt heart rate sensor at the center of your chest and in contact with your skin.
• To increase measurement effectiveness, dampen the electrode area with water or electrocar-
diograph electrolyte cream.
• People with sensitive skin can wear the chest belt over a thin shirt with the electrode area
damped with water.
• Hair on the chest may interfere with accurate measurements.
• Do not use this unit with other cordless devices (including CATEYE CC-CL200) or some
lamps (including CATEYE Stadium Light). Interference might occur, resulting in incorrect
measurement.
