sheath and then loosen the belt. After the “ V ” edges of the two sides of the belt fit well into the “ V ”
grooves on the two sides of the sheath, put the belt into the first lock bar to fasten the belt. See figure
12-4. If the belt is too much long, you may put it into the second lock bar. You must position the SpO
2
sensor in this way so as to make the photoelectric component face the correct position. In the mean
time, note not to elongate the belt too much, which may lead to inaccurate measurement and also
blocking the blood circulation severely.
