Scales that can measure up to 150kg, displaying in 50g increments. - Brand: TANITA - Model: BC-332L - Year of manufacture: 2023 - Measurement range: 0~150kg - Minimum display: 50g (0~100kg) / 100g (100~150kg) Thank you for viewing. There is no instruction manual or original box. This is a sale of the main unit only. The batteries are in the unit, and you probably won't need to replace them for a while. The instruction manual can be found on the TANITA website. You can also set it up initially from TANITA's official app, Health Planet. In that case, you can put the unit into pairing mode by long-pressing the setting button. I have used it less than 10 times since I bought it. Please understand that it is a used item before considering purchasing it.
