Installation Steps:
- Unpack Components: Carefully remove all parts from the packaging and verify against the included parts list.

5. Operating Instructions
To use your VIVO keyboard tray, simply pull the tray outwards from under your desk until it reaches your desired typing position. The smooth sliding mechanism allows for effortless extension and retraction. When not in use, push the tray back under the desk to save space and keep your workspace tidy.
The tray is designed to provide ergonomic typing angles, helping to relieve stress on your wrists and shoulders. Position your keyboard and mouse comfortably on the tray for optimal use.
6. Maintenance
Regular maintenance ensures the longevity and smooth operation of your keyboard tray:
- Cleaning: Wipe the tray surface with a soft, damp cloth. Avoid abrasive cleaners that could damage the finish.
- Check Fasteners: Periodically inspect all screws and clamps to ensure they remain tight. Loose fasteners can lead to wobbling or reduced stability. Tighten as needed.
- Lubrication: If the sliding mechanism becomes stiff over time, a small amount of silicone-based lubricant can be applied to the rails to restore smooth movement.
7. Troubleshooting
- Tray Wobbles:
- Ensure all C-clamps are securely tightened to the desk.
- Verify that the desk surface itself is stable and not prone to movement.
- Check that the screws attaching the side brackets to the tray are tight.
- Tray Does Not Slide Smoothly:
- Inspect the sliding rails for any obstructions or debris.
- Ensure the tray is installed level. Uneven installation can cause friction.
- Apply a small amount of silicone lubricant to the sliding rails if necessary.
- Keyboard/Mouse Does Not Fit:
- Refer to the "Compatibility & Dimensions" section to confirm your peripherals meet the tray's height and width limitations.
