R NOTE : After activation of the oxygen system the OXYGEN/PASSENGER
____ R P/BSW SYS ON legend stays on until the pressure in the R distribution lines is below 0.045 bar (0.6526 psi). The time R to depressurize is between 0.4 and 22 minutes. Time decreases R if cabin pressure is lower or if more oxygen masks are used.
