1. Insert the 90° fitting on the OPC inlet hose (36) into the
CPC connector (9) on the regulator. Insert the blue tipped
end of the outlet hose (35) into the 6mm connector (39) on
the OPC. Attach the coiled hose (33) to the CPC connector
on the outlet hose (35). Insert the coiled hose (33) into the
90° fitting on the index tube of the cannula (32) or facemask.
2. Turn the mode-selector knob to the ON position. A
successful Power-Up Test consists of the following: Both LEDs
flash 6 times, audible alarm beeps 3 times and a single puff
of oxygen should be emitted from the cannula via the OPC.
If during the Power-Up Test the battery LED displays continuous
single or double flashes, this indicates a low battery condition.
Replace the batteries immediately before continuing.
NOTE: The OPC will not deliver an oxygen pulse below
8,000 ft. PA while in ON mode other than during the
Power-Up Test.
