5. Press NIBP .

 For the password, enter 4258.
 Press the Enter key.
7. Press OVERPRESSURE TEST .
8. To begin the overpressure test, press the Test button, then
increase the pressure to the overpressure point:
 Increase pressure to approximately 280mmHg using the hand
bulb.
 Very slowly increase the pressure as you approach the
overpressure point.
 When the overpressure point is reached, the valves will open
(a faint click can be heard when this occurs) and the pressure
will rapidly reduce to 0 (zero) mmHg. Be sure to observe the
pressure measurement on the manometer when the valves
open.
9. Determine if the NIBP module passed the overpressure test:
 If the valves opened WITHIN the overpressure pass criteria,
then the NIBP module PASSED the overpressure test for adults
and pediatrics. Go to step 10.
 If the valves opened BEYOND the overpressure point pass
criteria, then press the Test button again to confirm the
overpressure point. If the valves open repetitively beyond the
pass criteria, contact Masimo Technical Services. See Masimo
Technical Services on page 248.
10. To stop testing, press Stop.
