The Master Grip attaches magnetically to the MagSafe-compatible phone case. Align the circular magnetic area on the grip with the corresponding area on the back of the phone case. The strong magnets will securely hold the grip in place. The grip can be attached in both vertical and horizontal orientations.

3. Bluetooth Pairing for Wireless Shutter

- On your iPhone, go to Settings > Bluetooth.

4. Accessibility Settings for Zoom Control
For full functionality of the zoom control, navigate to your iPhone's Settings > Accessibility > Zoom. Ensure Zoom is turned On. It is recommended to adjust the 'Maximum Zoom Level' to 1.2x to prevent excessive zooming.
5. Attaching the UV Filter
The UV filter slides into the designated guide rails around the camera module on the phone case. Gently push until it latches into place. This provides protection and can enhance image quality.

6. Attaching the Magnetic Fill Light
The Magnetic Fill Light attaches magnetically to the outer side of the Master Grip. It can be rotated to face forward (for selfies) or backward (for rear camera subjects). It also features a reflective mirror for easy subject monitoring.
Operating Instructions
1. Using the Shutter Button
The red shutter button on the grip functions like a traditional camera shutter:
- Half-press: Focuses the camera.
- Full-press: Captures a photo or starts/stops video recording (depending on the selected mode).
2. Zoom Control
Use the zoom lever/dial located near the shutter button to adjust the camera's zoom level. Push right to zoom in, push left to zoom out. This allows for precise control over your shot composition.
3. Switching Camera Modes
Rotate the mode dial on the grip to cycle through different camera modes such as Photo, Video, Portrait, and Spatial. Double-clicking the 'Fn' button will take you to the gallery.
4. Switching Front/Rear Cameras
Press the circular button on the grip to quickly switch between your iPhone's front-facing and rear-facing cameras.
5. Using as a Kickstand
The Master Grip can be folded to act as a kickstand, allowing you to prop up your iPhone for hands-free viewing, streaming, or scrolling. This is useful for desktop use or during travel.
6. Tripod Mounting
The bottom of the Master Grip features a standard 1/4-inch screw thread, allowing you to attach it to any compatible tripod or monopod for stable shots and extended shooting sessions.

7. Charging the Master Grip
The Master Grip has a built-in 3200mAh Lithium Polymer battery. Connect the provided USB-C charging cable to the port on the grip to recharge it. The grip also supports wireless charging for your iPhone via its MagSafe connection.
