If your SEFAM Medical Equipment displays 'Er 01' due to a patient settings problem, reinitialize the default settings by holding down the right control button for 2 seconds until the blinking “DEF?” message appears. Accept by pressing the On/Off button. The device will then be set to the default values and can be reset to your desired settings. If the error persists, further technical assistance may be required.
