2.2 Focusing

Adjust the eyepiece diopter by rotating the ring near the eye cup until the reticle appears sharp. Then, rotate the objective lens focus ring (located at the front of the scope) to achieve a clear and sharp thermal image of your target at various distances.

2.3 Image Modes and Palettes

The scope offers six distinct image modes (Red Hot, White Hot, Iron Red, Green Hot, Fusion, Ice Fire) to adapt to various environmental conditions and user preferences. Cycle through these modes using the designated button to optimize visibility and target recognition.

2.4 Zoom and Picture-in-Picture (PIP)

Utilize the digital zoom function (up to 12x) for closer inspection of distant targets. The Picture-in-Picture (PIP) mode provides a magnified view of the reticle area within a smaller window, allowing you to maintain a full field of view while focusing on a specific point.

3. Maintenance

3.1 Cleaning

Regularly clean the objective and eyepiece lenses with a soft, lint-free cloth specifically designed for optics. Avoid abrasive materials, harsh chemicals, or excessive pressure, as these can damage the lens coatings. The device is IP67 rated for water resistance, but proper drying after exposure to moisture is recommended.

3.2 Storage

Store the thermal scope in its protective carrying case in a cool, dry place, away from direct sunlight and extreme temperatures, when not in use. For long-term storage, it is advisable to remove the battery to prevent potential damage.

4. Troubleshooting

4.1 Common Issues

• No Image/Power: Check battery charge level and ensure the battery is properly installed with correct polarity.
• Blurred Image: Adjust the eyepiece diopter for clear reticle focus, then rotate the objective lens focus ring to sharpen the thermal image.
• Image Lag/Pixelation: This can occasionally occur during automatic calibration. Allow the unit to warm up for 5-10 minutes before extended use. If persistent, ensure firmware is up-to-date.
• Loss of Zero: If the point of impact shifts, re-zero the scope following the instructions in section 2.6. Ensure the mounting system is secure.
