2. Insert the pan handle into the rosette.
3. Tighten the pan handle locking knob until the handle is firmly secured in the desired position.

4. Operating

4.1 Balancing the Camera (Counterbalance)

Proper counterbalance is crucial for smooth operation and preventing the camera from tipping. The NH30 offers a 0+5 step counterbalance system, supporting loads from 2kg to 10kg.

1. With the camera mounted, release the tilt lock.
2. Adjust the sliding camera plate forward or backward until the camera is balanced and remains stationary when tilted to any angle.
3. If the camera still tips, adjust the counterbalance knob (usually a numbered dial) to increase or decrease the counterbalance force. Start from '0' and increase gradually until the camera is balanced.

4.2 Adjusting Pan and Tilt Drag

The NH30 features a metal layered unit drag mechanism for precise control over pan and tilt resistance.

1. Locate the pan drag knob and tilt drag knob on the head unit.
2. Rotate the knobs to increase or decrease the resistance for panning (horizontal movement) and tilting (vertical movement). Adjust to your preferred level for smooth, controlled shots.

4.3 Locking Mechanisms

Use the pan and tilt locks to secure the camera in a fixed position.

• Pan Lock: Tighten the pan lock knob to prevent horizontal rotation.
• Tilt Lock: Tighten the tilt lock knob to prevent vertical movement.

• Storage: Store the head unit in a clean, dry place, away from direct sunlight and extreme temperatures. It is recommended to store it in its original packaging or a padded case.
