Operating

1. Adjusting Shooting Orientation

The adapter features a 360° rotatable design, allowing you to switch between horizontal and vertical shooting modes without detaching your phone or the adapter from the optical device. Simply rotate the phone mount section to achieve the desired orientation.

2. Focusing and Image Capture

Once your phone and the adapter are securely attached, open your smartphone's camera application. Use the optical device's focus mechanism to achieve a clear image. Fine-tune the phone's position within the adapter if necessary to optimize the field of view and eliminate vignetting.

The slide design of the adapter allows for minor adjustments to the phone's camera position relative to the eyepiece, aiding in precise focusing.

Maintenance

1. Cleaning

• Adapter Body: Wipe the adapter's body with a soft, dry, lint-free cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid abrasive cleaners or solvents.
• EVA Pads: The EVA pads can be gently wiped with a damp cloth. Ensure they are completely dry before reassembly or storage.
• Avoid Water Immersion: Do not immerse the adapter in water or any cleaning solutions.

2. Storage

• Store the adapter in a cool, dry place away from direct sunlight and extreme temperatures.
• Keep the adapter in its original packaging or a protective pouch to prevent dust accumulation and scratches.

Troubleshooting

1. Phone Not Holding Securely

• Check Phone Width: Ensure your phone's width is within the 66-95mm range.
• Verify Clip Engagement: Make sure the spring clip is fully engaged and gripping the phone firmly.
• Remove Thick Cases: If your phone has a very thick case, it might interfere with the grip. Consider removing the case during use.

2. Adapter Not Attaching Firmly to Eyepiece

• Check Eyepiece Diameter: Confirm the eyepiece outer diameter is between 23-50mm.
• Use Correct EVA Pads: Ensure the appropriate EVA pads (2mm, 3mm, or 4mm) are used to create a snug fit for smaller eyepieces.
• Proper Clamping: Ensure the clamp jaws are fully released to grip the eyepiece.

3. Image is Blurry or Not Centered

• Align Phone Camera: Re-adjust your phone's position using the slide rail until its main camera lens is perfectly centered with the adapter's focusing hole and the optical device's eyepiece.
• Tighten Fixing Screw: Ensure the top fixing screw is tightened to prevent the phone from shifting out of alignment.
• Focus Optical Device: Use the focus knob on your telescope, monocular, or microscope to achieve a sharp image. The adapter does not provide focusing capabilities.
• Clean Lenses: Ensure both your phone camera lens and the optical device's eyepiece are clean.

4. Vignetting (Dark Edges in Image)

• Adjust Phone Position: Slightly adjust the phone's position within the adapter to find the optimal alignment that minimizes dark edges.
• Zoom In: Use your phone's digital zoom slightly to crop out the vignetting, if necessary.
