The green LED will flash letting the user know the Critical Alert
Universal is ready and has power. The analog gauge will read the
pressure in the oxygen cylinder and will be in the green area on the dial
when the cylinder is fully charged.

oxygen level gets to 500 psi and lower. The black snooze button , see

minutes of available oxygen.
