Operating Instructions
1. Setting Height for BMI Function
For accurate BMI readings, it is essential to set your height. For first-time use or after resetting the scale, press the "SET" button located on the top of the scale, between the up and down arrow buttons. Use the arrow buttons to adjust the height value to your personal height. This step ensures the scale can correctly calculate your BMI.

2. Taking a Measurement
Place the scale on a hard, flat surface. Avoid carpets or soft surfaces, as this can affect accuracy. Step onto the scale with bare feet. The scale features step-on technology and will automatically turn on and display your weight. After a few seconds, it will then display your BMI value.

Maintenance
Cleaning
Clean the scale with a damp cloth. Avoid water getting inside the scale. Do not use abrasive cleaners.
