NOTES:. I A vertical green color bond shows the normal operating<br />

range for the suit temperature (45 ° to 65°F). Red<br />

horizontal i;nes show limits for suit pressure (3.4 ps;o),<br />

cabin pressure (4.7 ps;o), and CO2 pressure (|5 mm Hg).<br />

A vertical yellow color Ixmd shows the caution range<br />

for CO 2 pressure(7.6 to 15 mm Hg).<br />

2..The PGA pressure indicator presents an operating rOfige<br />

frcxn 2 to 10 psio and a green and red color b_nd. The<br />

green I:_nd (3.5 to 10 psio) shows normal pressure<br />
