3. Setup and Assembly
Please follow these instructions carefully for proper assembly. It is recommended to have an electric screwdriver for easier installation of the tabletop.
3.1 Checking for Height Differences
Before assembly, verify if there is any height difference between the left and right support columns. This is crucial for proper desk operation.

Figure 3.1: Visual guide for checking and adjusting height differences between the desk legs before full assembly. If a height difference exists, loosen the screw and insert the propeller shaft to adjust.
3.2 Tabletop Installation and Screw Holes
When attaching the tabletop and the central beam, you may need to drill your own screw holes. An electric screwdriver is highly recommended for this step.
If you are using a FLEXISPOT tabletop, some pre-drilled screw holes may align with the leg plates, serving as a reference for positioning. Other screw holes are designed for different FLEXISPOT models.

4. Operating Instructions
The FLEXISPOT EF1 desk features an intuitive control panel for easy height adjustments and memory functions.
4.1 Adjusting Height
To adjust the desk height, simply press the up or down arrow buttons on the controller until the desired height is reached. The desk will move smoothly at a speed of 25mm/s.
4.2 Using Memory Presets
The controller allows you to save and recall up to four different height settings. To save a height:
- Adjust the desk to your desired height.
- Press the 'M' button (or similar memory button) followed by one of the numbered preset buttons (1, 2, 3, or 4). The height is now saved to that preset.
To recall a saved height, simply press the corresponding numbered preset button (1, 2, 3, or 4). The desk will automatically move to the saved position.
Note: The physical location of the controller on the desk may vary from some product images; the actual controller is typically located on the left side of the desk.
