Setup

- Remove Lens Caps:
Remove the objective lens cap from the front of the scope and the eyepiece cap from the rear. Store them in a safe place to prevent loss or damage.
- Adjust Eyepiece:
If your scope has an adjustable eyepiece, rotate it to a comfortable position for viewing. For eyeglass wearers, retract the eyecup. For non-eyeglass wearers, extend the eyecup.
- Optional: Attach Phone Adapter:
If using a phone adapter (sold separately), attach it to the eyepiece according to the adapter's instructions. Secure your smartphone in the adapter for digiscoping.

Operating Instructions
- Aiming the Scope:
Point the spotting scope towards your desired target. Use the tripod's pan and tilt adjustments to make broad movements.
- Adjusting Magnification (Zoom):
Rotate the zoom ring on the eyepiece to select your desired magnification between 25X and 75X. Start with the lowest magnification (25X) to easily locate your target, then increase as needed for more detail.

- Focusing:
Once the target is centered, slowly rotate the focus knob until the image appears sharp and clear. Fine-tune the focus for maximum clarity at your chosen magnification.
- Eye Relief:
Adjust the eyecup to achieve optimal eye relief, which is the ideal distance between your eye and the eyepiece lens for a full field of view. This is especially important for comfortable extended viewing.
Maintenance
- Cleaning Lenses:
Use the provided cleaning cloth or a soft, lint-free cloth specifically designed for optical lenses. Gently wipe away dust or smudges. For stubborn marks, use a small amount of optical lens cleaning fluid applied to the cloth, not directly to the lens.
- Body Cleaning:
Wipe the body of the scope with a soft, damp cloth. Avoid using abrasive cleaners or solvents.
- Waterproof and Fogproof Care:
While the scope is waterproof and fogproof, avoid unnecessary exposure to extreme conditions. After use in wet environments, wipe the scope dry before storing. Do not attempt to disassemble the scope, as this will compromise its waterproof and fogproof seals.

- Storage:
When not in use, store the spotting scope in its carrying case in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure lens caps are in place to protect the optics.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Image is blurry or out of focus. | Focus knob not adjusted correctly; high magnification without fine-tuning. | Rotate the focus knob slowly until the image is sharp. Start at lower magnification to find the target, then zoom in and refocus. |
| Dark or obstructed view. | Lens caps still on; objective lens or eyepiece dirty; incorrect eye relief. | Ensure both objective and eyepiece caps are removed. Clean lenses with a soft cloth. Adjust eyecup for proper eye relief. |
| Image appears shaky or unstable. | Tripod not stable; scope not securely mounted. | Ensure tripod legs are fully extended and stable on a flat surface. Tighten the scope's mounting screw to the tripod. Avoid touching the scope during observation. |
| Fogging inside the lens. | Extreme temperature changes; seals compromised (unlikely for new product). | Allow the scope to acclimate to ambient temperature. If fogging persists and is internal, contact customer support. External fogging can be wiped away. |
