How to use

Attach the interface arm to a compatible SYSTEM X horizontal rail according to the rail manufacturer's instructions, ensuring the rail and fixings are rated for the combined weight. Secure the display to the VESA 400 pattern on the arm, using appropriate screws for the screen model. Use the levelling screws to adjust vertical alignment after the screen is mounted. Adjust the tilt angle with the thumbwheels to the desired up to 20° position; thumbwheels allow fine tool-less adjustment and can be re-tightened to maintain angle. Verify all fastenings and the overall stability before leaving the installation.

Recommendations

Ensure the supporting SYSTEM X rail and building fixings are rated for at least the weight of the display plus a safety margin. Use manufacturer-recommended hardware for VESA 400 mounting and follow local installation regulations. For repeated adjustments or heavy screens near the 70 kg limit, check fixings periodically and re-tighten levelling screws and thumbwheels as needed.
