Key Assembly Steps
- Desktop Preparation: Place the desktop (A) on a T-shaped board (cardboard packaging) for protection during assembly.
- Desk Extensions: Align and fully insert the desk extensions (B) into both sides of the desktop. Secure them by tightening the screws with the provided T25 screwdriver and covering with screw caps.
- Integrated Power Supply Column: Decide whether you want the power cable on the left or right side of the desk. The desk is pre-configured for the left side.
- Connecting Leg Columns: Place the leg columns (C, D) into the desk frame. Plug the corresponding cables from the leg columns into the control box. Ensure cables are tucked neatly.
- Assembling Cable Tray: Attach the mounting brackets (E) to the desktop. Align the cable tray (F) with the alignment notches on the brackets and magnetically snap it into place. Secure with screws.
- Assembling Desk Feet: Attach the left and right desk feet (G) onto the leg columns, guiding the power cable through the opening in the desk foot. Ensure the longer end of each foot faces the front of the desk. Secure with screws.
- Flipping the Desk Upright: With at least two people, gently tilt the desk 90 degrees until the control panel is facing downwards, resting on the packaging foam layer. Then, grip the desktop and side frame firmly and gently tilt it 90 degrees to an upright position. Ensure the desk is stable and balanced before releasing your grip.
- Powering the Desk: Connect the power cord (J) with the socket located at the bottom of the leg column. Plug the other end of the power cord into a compatible power outlet.
- Initial Calibration: Before first use, the desk must be calibrated. Slide the standby switch to the right to activate the control panel. Press and hold the 'down' button until the display shows 'RST' and you hear a beep. The desk will move to its lowest position and then stop. The calibration is complete.
Operating Instructions
The Secretlab MAGNUS Pro XL offers intuitive controls for height adjustment and cable management.
Height Adjustment
To adjust the height of your desk, press and hold the up or down arrow buttons until the desk reaches your desired position. For precise adjustments, tap the buttons to move the desk in millimeter increments. Always ensure the area around your desk is free from obstacles and keep at least 25mm (1 inch) of clearance around the desk edges.

Saving Height Presets
The integrated backlit control panel allows you to save up to three custom height presets for effortless transitions:
- Adjust the desk to your preferred height.
- Press the 'S' button on the control panel.
- Then, press the desired preset button (1, 2, or 3) to save the current height.
Standby Switch
The control panel can be disabled to prevent accidental activation or movement of the desk. Slide the switch to the left to turn it off. Slide it to the right to turn it back on.
Cable Management
The MAGNUS Pro XL features a top-access full-length cable management tray and a full magnetic desktop surface for superior cable organization.
- Cable Management Tray: To open the tray, push the top of the handle down to release it from the magnets. To close it, lift the handle upward until magnets snap it into place.
- Magnetic Desktop Surface: Utilize the full magnetic desktop surface and dedicated modular, magnetic desk accessories (sold separately) to organize your space with monitor arms, cable anchors, and more.

Ergonomics
Achieving optimal ergonomic posture is essential for comfort and health.
- Sitting Posture: Adjust your chair so your feet are flat on the floor, knees bent at 90 degrees, and armrests raised so your elbows are bent at 90 to 120 degrees. Adjust your head pillow to support your neck. Adjust the desk height so your armrests are level with the desktop.
- Standing Posture: Stand with your feet shoulder-width apart, shoulders relaxed, and back straightened. Adjust the desk height so your elbows are bent at 90 degrees.
- Monitor Placement: Adjust and position the top of your monitors at eye level for both sitting and standing postures.
