4.4 Special Functions

• TARE Function: Press the 'TARE' button to zero out the weight of an item (e.g., a blanket or diaper) placed on the scale before weighing the child. This ensures only the child's weight is measured.
• HOLD Function: If the child is moving, press the 'HOLD' button. The scale will capture and display a stable weight reading once detected, even if the child continues to move.
• Breast-Milk-Intake-Function (BMIF): This function allows for the calculation of breast milk intake. Weigh the infant before feeding, then weigh them again immediately after feeding. The scale will display the difference, indicating the amount of milk consumed. Refer to the specific instructions in the full manual for detailed steps on activating and using BMIF.

5. Maintenance

5.1 Cleaning

Clean the scale regularly with a damp cloth and a mild detergent. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the surface and electronic components. Ensure no liquid enters the display or button areas.

5.2 Battery Replacement

When the battery indicator appears on the display, replace all four AA batteries promptly to ensure continued accurate operation. Refer to Section 3.2 for battery installation instructions.

6. Troubleshooting

• Inaccurate or Inconsistent Readings:
  • Ensure the scale is placed on a hard, flat, and stable surface, not on carpet or uneven flooring.
  • Minimize movement of the child during weighing. Use the HOLD function for restless infants.
  • Check battery level and replace if low.
  • Re-tare the scale (press TARE) before each measurement, especially if a blanket or clothing is used.
• Scale Not Powering On:
  • Verify that the batteries are correctly inserted with the proper polarity.
  • Replace old or depleted batteries with new ones.
