This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current.

This machine is equipped with a power cord that has an equipment-grounding wire and a grounding plug. Only insert plug into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances. DO NOT modify the provided plug!

During height adjustments, if the table comes into contact with another object, movement will automatically cease. To adjust the level of sensitivity, press the buttons at the same time. The LED will display A-1 (low), A-2 (medium), and A-3 (high). Press the buttons to scroll through the selections. After five seconds, the selection will be automatically saved.
