Symptom: The Performance Monitor is displaying E011 or E012.
Resolution: This indicates a non-serious error code that is built into the PM. Clear the error code as follows:
- Press and hold the four bottom buttons on the face of the monitor (Recall, right arrow, up arrow and OK).
- While holding these buttons, press and release On/Off.
- Release the four buttons. The monitor will do some fast counting for 10–15 seconds and then display a number 5 in the center area.
- When the 5 appears, press and release On/Off again. Zeros should come up and the monitor should work. If it doesn’t, you may need to replace the PM.
