On the Emergency oxygen walk around bottle, which setting on the selector knob supplies oxygen only on demand at all altitudes up to 30,000 feet?

The knob setting being tested is about how and when oxygen is delivered from the emergency oxygen walk-around bottle. In the NORM position, the system is configured for oxygen to flow only when you inhale (on demand) and it’s designed to function up to 30,000 feet. This makes it the best fit for delivering oxygen exactly when you need it while conserving the supply across that altitude range.

The other settings don’t meet this on-demand requirement: FULL would push oxygen out continuously, OFF would provide no oxygen, and ON DEMAND is not the mode described for this device’s on-demand behavior across the tested altitude range.
