The O/R (override) position allows a crewmember's communication to take
priority over any traffic on the intercom channel no matter what other crewstation
FFCSs are set on. The O/R position is a momentary position, therefore the
INTERCOM switch must be held in this position for the duration of the
communication. When the switch is released it returns to the VOX position.
