Memory position operation:
When the column is stopped, press and hold any of the keys “1”, “2”, “3” or “4” for more than 3 seconds, then the current height position of the column will be saved to the corresponding key.
The hand controller can memorize a total of 4 height positions, is repeatable and can be saved even after a power failure.
Once the memory position has been set, press any of the “1”, “2”, “3” or “4” buttons directly, the table will automatically move to the memory position of the corresponding key. Press any key to stop the column in the process of running to the memory position.

1. Initial power-up of the product:
   When the controller is connected to the power supply according to the instructions on the controller nameplate, the buzzer will sound twice and the software version number will be displayed for 1 second, followed by the current height. If the height value displayed by the hand controller does not correspond to the actual height of the column, or if the height of the column has changed after reassembly, the reset operation is required. Otherwise, it can be used directly according to the factory preset.

2. Reset operation:
   (1) When the system moves to the lowest position, release the key, then press and hold the down “▼” key for 5 seconds without releasing, at this time the system enters the reset mode and the display shows RST. In the process of reset, if you encounter an  unexpected situation, you can always release the down “▼” key to stop the table from running. Press and hold the down “▼” key again to continue the reset. Wait for the buzzer to sound a “beep”, indicating that the reset operation is complete, at this time the  hand controller shows the lowest height of the desk.
   (2) When the table has been set to the lowest limit, and the lifting column runs to the limit position, then press and hold the down “▼” key for 5 seconds without releasing, then the system will enter the reset mode and the display will show RST. (When the reset process encounters unexpected situation, you can always release the down “V ” key, the table stops running. Press the down “▼” key again to continue the reset). Wait for the buzzer to sound a “beep”, indicating that the reset operation is complete, at this time the hand controller shows the lowest height of the desk.
   (3) When the hand controller is abnormal, “▼” will be displayed in the screen. Then press and hold the DOWN “▼” key for 5 seconds without releasing, the system will enter the reset mode and the display will show RST. In case of unexpected situation during  the reset process, you can release the “▼” key at any time and the table will stop running. Press the down “▼” key again to continue the reset.
