I had 2500 hours in them, long ago. There was no “bleeds off” procedures. IIRC, the switch on the right side pedestal below the radio panel, was OFF, L, NORM, R, EMER. It was left in NORM all the time that I recall. Light, it’d climb pretty fast and there’s no aural warning, the Master Warning on the glareshield and CABIN ALT message. At 10,000’, hypoxia isn’t very apparent, so might have been working a problem, while not leveling at 10,000’. Bad idea.
