3. Setup Instructions
Follow these steps to assemble and install your OMOTON GH04 stand:
3.1. Attaching the C-Clamp Base
- Identify a suitable surface for mounting, such as a desk, headboard, or table. The C-clamp can accommodate surfaces up to 2.55 inches (approximately 6.5 cm) thick.
- Place the C-clamp base onto the edge of your chosen surface.
- Tighten the screw mechanism on the C-clamp until it is firmly secured to the surface. Ensure the clamp is stable and does not wobble. The base features rubber padding to protect your furniture from scratches.

3.2. Attaching the Arm Assembly
- Insert the main arm assembly into the designated slot on the C-clamp base.
- Rotate the tension control knob on the base to secure the arm. Adjust the tightness to allow for smooth rotation while maintaining stability.
3.3. Attaching the Device Holder (Magnetic Head or Tablet Clamp)
The OMOTON GH04 stand offers two options for holding your device:
- For Magnetic Phone Head: Attach the magnetic phone head to the end of the arm. This is suitable for phones with built-in magnetic capabilities (e.g., iPhone 12-17 series) or other phones/cases with an included metal ring.
- For Plastic Tablet Clamp: Attach the plastic tablet clamp to the end of the arm. This clamp is designed for tablets and larger phones ranging from 4 to 13 inches.

4. Operating Instructions
Once assembled, the OMOTON GH04 stand offers flexible positioning for your device.
4.1. Attaching Your Device
- For Magnetic Head: Simply bring your compatible phone close to the magnetic head. The strong magnets will securely attach the device.
- For Tablet Clamp: Gently pull apart the adjustable grips of the plastic clamp and insert your tablet or phone. Release the grips to secure the device. Ensure the device is centered and held firmly.

4.2. Adjusting the Arm and Viewing Angle
The stand features multiple flexible rotating shafts and a 360-degree rotating base for precise positioning:
- Arm Adjustment: The multi-joint aluminum alloy arm can be extended, retracted, and angled to achieve your desired height and distance. The joints are designed to be stiff to prevent sagging, providing stable placement.
- Device Rotation: The device holder can rotate 360 degrees, allowing you to switch between portrait and landscape orientations.
- Base Rotation: The base also rotates 360 degrees, providing flexibility to swing the entire arm assembly out of the way when not in use or to share your screen.

5. Maintenance
To ensure the longevity and proper functioning of your OMOTON GH04 stand, follow these simple maintenance guidelines:
- Cleaning: Wipe the aluminum alloy surfaces with a soft, dry cloth. For stubborn marks, a slightly damp cloth can be used, followed by immediate drying. Avoid abrasive cleaners or solvents.
- Joints: The joints are designed to be stiff for stability. Do not attempt to lubricate them unless specifically instructed by OMOTON support, as this may affect their holding strength.
- Storage: When not in use for extended periods, store the stand in a clean, dry environment.
6. Troubleshooting
If you encounter any issues with your OMOTON GH04 stand, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Stand feels unstable or wobbles. | C-clamp not tightened sufficiently; surface too thin or uneven. | Ensure the C-clamp is securely tightened to a stable surface. Verify the surface thickness is within the 2.55-inch limit. |
| Arm joints are too stiff to adjust. | Joints are designed for firm hold; initial stiffness is normal. | Apply firm, steady pressure when adjusting the arm. The stiffness ensures the arm holds its position. Avoid excessive force. |
| Device is not securely held by the clamp/magnetic head. | Device size incompatible; magnetic ring not applied (for non-magnetic phones). | Ensure your device (4-13 inches) is correctly placed in the tablet clamp. For magnetic attachment, confirm your phone has built-in magnetic capabilities or that a metal ring is properly affixed to your phone/case. |
| Stand does not fit behind a headboard. | Design of the C-clamp and arm orientation may not suit narrow gaps. | The stand's design may not be ideal for very narrow spaces between a wall and a headboard due to the tightening knob and arm pivot. Consider mounting on a nightstand or desk instead. |
If the problem persists after attempting these solutions, please contact OMOTON customer support for further assistance.
