*Critical alarm conditions will render the O
selectable limit of 3.5 mA or 21.6 mA (position 3 of SW2). Factory default value is 3.5 mA. Alarms which are not self-clearing
(Self-Clearing = NO) will require a reset. Perform the Reset Procedure in Section 2: Configuration of Oxymitter 4000 with Membrane Keypad to
continue operation.
**The CALIBRATION RECOMMENDED alarm flashes the Calibration Recommended LED on the operator's keypad.
