This stand connects directly to the VESA hole pattern on the back of your monitor, offering two distinct height adjustments: 30mm or 50mm from the table surface to the bottom of the monitor.
Setup Instructions
- Unpack Components: Carefully remove all components from the packaging. Verify that all parts are present.
- Identify VESA Mounting Points: Locate the VESA mounting holes on the back of your compatible NEC Pxx4 or Vxx4 series monitor.
- Attach Stand to Monitor: Align the stand's mounting plate with the VESA holes on the monitor. Secure the stand using the provided screws. Ensure a firm connection.
- Adjust Height: The stand allows for 30mm or 50mm adjustment from the table to the bottom of the monitor. Select the desired height by adjusting the vertical posts and securing them in place. Refer to the stand's design for specific locking mechanisms.
- Position Monitor: Place the assembled monitor and stand on a stable, flat tabletop surface.
Note: Always ensure the monitor is securely attached to the stand before placing it on a surface. Refer to your monitor's manual for specific VESA mounting instructions if needed.
Operating the Stand
The NEC ST-401 stand is primarily a static support and height adjustment accessory. Once set up, its operation involves maintaining its position and ensuring stability.
- Height Adjustment: To change the height (between 30mm and 50mm), carefully lift the monitor slightly, disengage the locking mechanism on the vertical posts, adjust to the desired height, and re-engage the lock. Always support the monitor during adjustment.
- Stability Check: Periodically check that the monitor is stable on the stand and that all connections remain secure.
Maintenance
Proper maintenance ensures the longevity and continued stability of your NEC ST-401 tabletop stand.
- Cleaning: Use a soft, dry cloth to wipe down the stand. For stubborn marks, a slightly damp cloth with mild soap can be used, followed by drying thoroughly. Avoid abrasive cleaners or solvents.
- Inspection: Regularly inspect the stand for any signs of wear, damage, or loose connections. Ensure all screws are tight.
- Storage: If storing the stand separately, keep it in a dry, cool place away from direct sunlight and extreme temperatures.
Troubleshooting
This section addresses common issues you might encounter with the NEC ST-401 tabletop stand.
- Stand is Wobbly:
