scale is equipped with a level indicator at the front panel. Adjust the feet until the air bubble
in the indicator is centered as shown.
Note: The scale should be levelled each time it is placed on a new surface.
Power Supply
Make sure the rechargeable battery is installed in the battery box in the underside of the
scale.
Alternatively, plug the adaptor into the port on the underside of the scale.
