Please follow the instructions below to perform a simple reset, which will fix 99% of issues.

  1. Ensure your desk is plugged into a functioning wall outlet.
  2. Ensure that the black power box (under the desk) does not have any loose connections.
  3. Removed all items from underneath your desk (so they don’t get crushed when the desk lowers to lowest position)
  4. From any position, press and hold the down arrow button on the keypad
  5. Continue holding the down arrow until your desk reaches its lowest position
  6. Stop pressing the button, and pause for 1 second.
  7. Press and hold the down arrow button until ASR or RST is displayed on the screen (Could take up to 30 seconds)
  8. Stop pressing the button, and pause for 1 second.
  9. Press and hold the down arrow button again until the desk lower (to the lowest possible position) and then raises slightly.
  10. Once a height number (inches or CM) is displayed, you can let go of the down button; your desk has been reset.

General Notes:

  • If a height is shown on the display, or if your desk moves when you press the up button, then you know the reset is complete.
  • If your desk uses a standard keypad, please follow the same procedure.
