5. Assembly Instructions
The FLEXISPOT EJ2 desk frame features a simplified assembly process with pre-assembled leg components, making installation quicker and easier. We recommend two people for assembly due to the weight of the components.
- Unpack Components: Carefully remove all parts from the packaging and lay them out on a soft, clean surface to prevent scratches.
- Attach Legs to Beams: Connect the pre-assembled leg columns to the main beam structure using the provided screws and tools.
- Install Feet: Secure the feet to the bottom of the leg columns.
- Mount Desktop: Place your chosen desktop (sold separately) onto the assembled frame. Align the desktop and secure it to the frame using appropriate screws. A power drill can expedite this step.
- Connect Control Panel and Power: Attach the control panel to the underside of the desktop and connect all necessary cables to the control box. Plug the power adapter into the control box and then into a wall outlet.

Memory Function
The desk allows you to save frequently used heights for quick adjustment.
- Adjust the desk to your desired height using the up/down arrows.
- Press the 'M' button. The display will show 'S-'.

Anti-Collision Feature
The desk is equipped with an anti-collision system that automatically stops and reverses movement if it encounters an obstacle during height adjustment. This prevents damage to the desk or objects.

Anti-Collision Mechanism
The sensitivity of the anti-collision feature can be adjusted in three levels. Refer to the detailed instructions in the included manual for how to adjust this setting.
