  If your Sunny Health & Fitness Fitness Equipment displays error code E4, it could be due to a few reasons. First, make sure you place your hands on the handle pulses immediately after pressing the START button. If that doesn't work, the Body Fat Function may not be receiving a pulse signal. Try plugging in the handle pulse wires again, or consider replacing them. If the issue persists, the meter may need to be replaced.

  If your Sunny Health & Fitness Fitness Equipment shows error E2, it indicates an issue with the EEPROM data. This could mean that no EEPROM data was read. In this case, try re-connecting the meter. Alternatively, there might be an error reading the EEPROM data. To resolve this, power the meter off and on again to re-read the data.
