Setup Instructions

- Install the Extension Riser (Optional):
If additional height is required, screw the 150mm (5.9-inch) extension riser onto the top of the boom arm's microphone mounting point. Then, attach the microphone clip or adapter to the top of the riser.

Operating Instructions
The CMTECK AR-16 boom arm offers flexible positioning for your microphone.
- Horizontal Adjustment: The arm can rotate 360 degrees at the base clamp and offers a 14x14-inch horizontal boom length for extensive reach.
- Vertical Adjustment: The arm allows for 220-degree vertical adjustment at its joints, enabling you to position your microphone at various heights and angles.
- Ball Head Adjustment: The microphone clip features a 360-degree rotatable ball head for precise microphone angling. Loosen the locking nut to adjust, then tighten to secure.
- Damping Adjustment: The joints of the boom arm include damping adjustment mechanisms. These can be tightened or loosened to control the stiffness of the arm's movement, allowing you to set the desired resistance for smooth positioning.


Maintenance
To ensure the longevity and optimal performance of your CMTECK AR-16 Microphone Boom Arm, follow these simple maintenance guidelines:
- Cleaning: Wipe the boom arm with a soft, dry cloth to remove dust and fingerprints. Avoid using abrasive cleaners or solvents, as these can damage the finish.
- Check Connections: Periodically check all screws and clamps to ensure they are securely tightened. This prevents unwanted movement or instability during use.
- Lubrication: The joints are designed for smooth operation and generally do not require lubrication. If movement becomes stiff, ensure no debris is obstructing the joints.
- Storage: When not in use for extended periods, you may detach the arm from the clamp and store it in a dry, clean place to prevent dust accumulation.
Troubleshooting
If you encounter any issues with your microphone boom arm, refer to the following common problems and solutions:
- Microphone Sags or Does Not Hold Position:
- Ensure the locking nut on the ball head is fully tightened after positioning your microphone.
- Check the damping adjustment screws on the arm joints. Tighten them slightly to increase resistance and hold heavier microphones more securely.
- Verify that your microphone's weight does not exceed the arm's maximum capacity of 4.4 pounds (2 kg).
- Arm Feels Loose or Unstable:
- Re-tighten the C-clamp to the desk. Ensure the desk surface is flat and provides a secure grip.
- Check the connection point where the boom arm inserts into the C-clamp for any looseness.
- Difficulty Adjusting Arm Movement:
- Loosen the damping adjustment screws slightly if the arm is too stiff to move.
- Ensure no cables or other objects are obstructing the arm's movement.
