Why do random values appear on the LCD of my Little Martin’s Medical Equipment?
- R
  Randy HarrisAug 3, 2025
  Random values may appear on the LCD of your Little Martin’s Medical Equipment due to several reasons: * Friction between the probe and abdomen skin during the search for the fetal heart can cause incorrect readings. Applying a coupling agent may resolve this. * Electromagnetic interference from sources like high-frequency generators or cellphones can also cause this issue. Try using the device in an area free from such interferences. * Fetal movement can change the position of the fetal heart. Adjust the probe to the location where the fetal heartbeat sound is loudest.

  Excessive noise when using your Little Martin’s Medical Equipment can be addressed by: 1. Applying a coupling agent, if you aren't already. 2. Avoiding direct probe contact with the skin while searching for the fetal heart. Find the optimal angle between the probe facet and the abdomen skin for the clearest sound. 3. Ensuring the probe is correctly positioned to detect the fetal heart.
