Setup
Step 1: Choose Mounting Option (C-Clamp or Grommet Base)
The monitor arm offers two installation methods to suit your desk type. Both options are compatible with desk thicknesses between 0.39 inches and 1.8 inches (10mm - 45mm).
For grommet mounting, your desk must have a cable grommet hole with a diameter of at least 2.4 inches (60mm).

Refer to the detailed instructions in the included user manual for specific steps on C-clamp or grommet base installation.
Step 2: Attach VESA Plate to Monitor
Secure the VESA plate to the back of your monitor using the appropriate screws and spacers from the hardware kit. Ensure the plate is firmly attached and aligned with your monitor's VESA mounting holes (75x75mm or 100x100mm).

Gas Spring Tension Adjustment
The gas spring mechanism allows for smooth and stable height adjustments. If your monitor sags or is difficult to move, you may need to adjust the gas spring tension:
- To adjust for lighter monitors, turn the adjustment screw clockwise.
- To adjust for heavier monitors, turn the adjustment screw counter-clockwise.
Use the provided Allen wrench to make small adjustments until the arm holds your monitor securely in any position. Ensure the arm is kept in a horizontal level during adjustment.

Maintenance
To ensure the longevity and optimal performance of your WALI monitor arm, follow these maintenance guidelines:
- Cleaning: Wipe the arm and base with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the finish.
- Periodic Checks: Periodically check all screws and connections to ensure they remain tight. Re-tighten if necessary.
- Gas Spring: If the monitor arm's movement becomes stiff or loose over time, re-adjust the gas spring tension as described in the 'Operating' section.
Troubleshooting
Monitor Sags or Does Not Stay in Position
Solution: The gas spring tension may be too low for your monitor's weight. Refer to the 'Gas Spring Tension Adjustment' section under 'Operating' and turn the adjustment screw counter-clockwise to increase tension until the monitor holds its position.
Monitor is Difficult to Move Up or Down
Solution: The gas spring tension may be too high. Refer to the 'Gas Spring Tension Adjustment' section under 'Operating' and turn the adjustment screw clockwise to decrease tension until the monitor moves smoothly.
USB Ports Not Functioning
Solution: Ensure the USB cables from the monitor arm base are securely connected to the USB 3.0 ports on your computer. Check your computer's device manager to confirm USB drivers are installed correctly.
