loose fitting the chest strap on your
chest.
2) Connect one connector with the chest

completely lodged into the chest strap.
3) Fit the chest strap on your chest with
one hand.
4) Connect the opposite connector to the
chest strap with the another hand.
5) Fasten the elastic band until it is fitted
