Cause:
Skin is not wet, or no contact with electrodes.

Correction:
Wet the electrodes by filling the cradle with the supplied fluid and placing the monitor in the cradle for one minute. Press the monitor on the breast until all four electrodes are in full contact with the skin.

Cause:
Battery is low. A low battery mark () should appear as well.

Correction:
Replace with 3 new AAA Alkaline batteries.

Possible causes:
1) User did not follow the instructions correctly.

2) Calibration is not successful due to location of glandular tissue being too far from the electrodes.

Correction:
First try to perform correct calibration and to follow instructions as accurately as possible. If results are not satisfactory, try changing the electrode location on your breast according to the place you feel fullest when you are late in breastfeeding.

Possible causes:
1) Unsteady measurement conditions (indicated with "" sign on the display).

2) Milk ducts in the breast are filled during measurement.

3) Local distortions in the breast, just below the electrodes.

Correction:
1) Measure with correct posture of the body, at the exact same point on the breast each time. Use the monitor in relaxed conditions.

2) Avoid measuring if the breast drips. Pay attention to your emotions and state of mind that influence your breast activity and that cause milk ducts to be filled.

3) As a last possibility, consider changing the location of electrodes 0.39 inches (1 cm) to the right or left and stick to it in all measurements.

Possible causes:
1) There are no batteries in the MilkSense monitor.

2) General USB failure.

Correction:

2) Check the USB cable by replacing with another micro-USB cable.

Cause:
Monitor is locked when held in the cradle or connected via USB cable.

Correction:
Remove the USB cable and take the monitor out of its cradle in order to operate.

Cause:
The monitor is resting in the wrong orientation in the cradle.

Correction:
Place the monitor in the cradle so that the display is in line with the MilkSense logo side of the cradle.
