of the inner surface of the sensor unit
sufciently with water.

●
Take care not to shorten the rubber strap too much to wear the chest
strap too tightly around your chest, as this may cause you to feel sick,
putting pressure on your heart. If you nd the chest strap too tight,
loosen the rubber strap immediately.
● The rubber strap is consumable. Its elasticity reduces with use, and the
chest strap will not t well around your chest even if its length remains
the same. If you nd the chest strap loose around your chest, shorten
the rubber strap length for secure t.
● If you feel the chest strap still loose around your chest after shortening
the rubber strap length, the rubber strap has reached the end of its
serviceable life. It is recommended that a new rubber strap be
purchased at the retailer from whom your HRM Watch was purchased.
