Height Adjustable Function:

To lower the desk, press and hold the "▼" button.

Height Memory Function:

To save a height: While the desktop is static, press and hold a memory button (e.g., "1") for three seconds. The buzzer will sound, and the display will show "S-1" (for button "1"), indicating successful saving.
To recall a saved height: Click the corresponding memory button (e.g., "1") to move the desk to the saved height.

Reset Function:

Standard Reset: If the desk height does not match the actual height, simultaneously press and hold the "3" and "4" buttons for three seconds to enter reset mode. The display will show "ASI". Then, press and hold the "▼" button to start the reset. The tabletop will rebound after reaching the lowest position, and the reset is complete when "bot" is displayed. Note: This operation clears original memory settings.
Reset at Lowest Position: If the desk is already at its lowest position ("bot" displayed), press and hold the "▼" button to enter reset mode. The display will show "ASI". Then, press and hold the "▼" button again to start the reset. The tabletop will rebound after reaching the lowest position, and the reset is complete when "bot" is displayed. Note: This operation does not clear original memory settings.

Anti-collision Sensitivity Adjustment (Optional):

Simultaneously press and hold the "▲" and "▼" buttons for three seconds to cycle through sensitivity levels: A-0 (closed), A-1 (high sensitivity), A-2 (medium sensitivity - factory default), A-3 (low sensitivity).
The desk will rebound immediately if it encounters an obstacle during upward or downward movement to prevent collisions.

Code Processing (Troubleshooting):

If "ASI" or "rSt" appears, press and hold the "▼" button to start the reset.
If "E01" or "E02" appears, allow the desk to rest for more than 18 minutes before normal use.
If other codes appear and holding the "▼" button yields no response, check cable connections, cut power for 10+ seconds, then restore power and perform a reset if "ASI" or "rSt" is displayed.
If issues persist, contact customer service.
