CUSTOMIZATION QUESTIONS Can I adjust the brightness of the screen? Only on the InBody230/320. Depending on the year the unit was manufactured, there will be either a knob or a hole behind the head of the unit next to the USB port. You can either turn the knob for brightness or you will need a Philips screw driver to turn the knob internally.
