Monitor Displaying Other Error Codes (E001–E010)

Symptom: The Performance Monitor is displaying other error codes (E001–E010).

Resolution: These codes may indicate a more serious problem with your monitor. Try to clear the error as follows:

  1. Change the batteries.
  2. Press and hold the four bottom buttons on the face of the monitor (Recall, up arrow, down arrow and OK).
  3. While holding these buttons, press and release On/Off.
  4. 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.
  5. 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.
