1. Ensure that your device is running the latest firmware. If not, update it by checking for updates here.
2. If the firmware is up-to-date but the issue persists, download the video to your iPhone and use an alternative media player like VLC to play the file.

1. Ensure the device is fully switched off by holding the ON/OFF button for more than 3 seconds until a countdown appears. Pressing the button for less than 3 seconds activates “Display Off” mode, which still consumes power.
2. Confirm your device has the latest firmware installed for optimal energy efficiency.
3. If storing the device for a long period, note that batteries naturally lose charge over time. Follow the user manual to maintain battery health.

• Vertical stripes
• Ghost images of previous objects

• The longer a thermal imager operates continuously, the less frequent calibration is required.
• Calibration intervals depend on operating conditions and image quality.

1. Automatic mode (default):
   • The software automatically determines when calibration is needed.
   • Recommended for consistent performance without manual intervention.
2. Manual mode:
   • You can switch to manual calibration in the “Main Menu” > “Calibration Mode.”
   • Important: Close the lens cover before performing manual calibration to ensure accuracy.

How to repair defective pixels:

1. Access the Pixel repair menu:
   • Open the device menu and select Pixel repair.
2. Use Picture-in-Picture (PiP) mode:
   • The screen will display an auxiliary cross in PiP mode.
3. Locate the defective pixel:
   • Use the navigation buttons to move the cross to the location of the bad pixel.
   • The defective pixel should disappear once the cross is correctly aligned.
4. Confirm the repair:
   • Press the ON/OFF button and wait for the “OK” message on the display.

• Resolution: 640×480 pixels
• Pixel Pitch: 12 µm
• Thermal Sensitivity (sNETD): <20 mK

Charging options:

1. Wireless charging:
   • Use a standard wireless induction charger.
   • Important: Remove the battery cap before charging.
2. Wired charging:
   • Connect the battery directly to a network adapter via the USB Type-C port.

Key differences:

Which one to choose?

• Telos XG50 offers higher base magnification and longer detection range (2300m), making it ideal for long-distance observation.
• Telos XL50 comes with a higher resolution sensor and a wider field of view, which ensures easier observation of large areas and a more detailed image.

• First, adjust the diopter adjustment on the eyepiece to clearly see the icons on the display and in the status bar.
• Second, adjust the lens focus to see the object of observation clearly. Please note that re-focusing may be required as the distance to the object changes.
• Do the image calibration – either in manual mode (with lens cover closed) or in automatic mode.
• Select the most suitable sensitivity amplification level – Normal, High, or Ultra, depending on the specific observation conditions.
• Go through the different color palletes.
• Manually adjust display contrast and brightness. We recommend keeping those two values at similar levels. A huge difference between them badly affects the image quality.

1. Target surface reflection:
   • Measurement accuracy and maximum range depend on the reflectivity of the target surface.
   • Reflectivity is influenced by surface texture, color, size, and shape.
   • Bright or shiny surfaces reflect better than dark or matte surfaces.
2. Environmental conditions:
   • Light conditions, fog, haze, rain, or snow can affect measurement accuracy.
   • Ranging performance may degrade in bright sunlight or when pointing the device toward the sun.
3. Target size and distance:
   • Measuring the range to a small-sized target is more challenging than to a large one, especially at distances greater than 400 meters.
4. Stabilization for long-distance measurement:
   • For small targets at long distances, stabilize the device by resting your elbow on a solid surface to counter hand tremors and ensure the beam accurately hits the target.

1. Adjust dioptre and lens focus:
   • Dioptre adjustment: Rotate the eyepiece dioptre rings to clearly see the icons on the display and the status bar.
   • Lens focus: Adjust the lens focus to ensure the object is clear. Re-focus as the distance to the object changes.
2. Perform image calibration:
   • Manual mode: Close the lens cover and calibrate manually.
   • Automatic mode: Let the device handle calibration automatically.
3. Optimize amplification levels:
   • Select the appropriate amplification level (“Normal,” “High,” or “Ultra”) based on observation conditions.
4. Experiment with color palettes:
   • Switch between different color palettes to find the most suitable one for your environment.
5. Adjust contrast and brightness:
   • Keep contrast and brightness at similar levels for optimal image quality. Avoid a large disparity between the two settings.
6. Check the Smoothing Filter:
   • If needed, toggle the Smoothing filter on or off to improve image clarity.

• Level the microbolometer’s background temperature, ensuring consistent performance.
• Eliminate image flaws, such as vertical stripes or ghost images of previously viewed objects.

• The intervals between calibrations depend on operating time:
  • Longer operating periods require less frequent calibration.

1. Turn off the proximity sensor:
   • Go to the device settings and disable the proximity sensor. For detailed instructions, visit the Merger LRF Manual.
2. Manual display control:
   • When the proximity sensor is disabled, you can manually turn the display on/off by pressing the ON/OFF button.

1. Close the lens cover during manual calibration:
   • Ensure the lens cover is closed fully when performing manual calibration.
2. Switch to automatic calibration mode:
   • If you prefer not to close the lens cover manually, enable the automatic calibration mode, which performs the process automatically.

• Switch to manual calibration mode to eliminate the clicking noise.
• Important: When using manual calibration, ensure the lens cover is closed during calibration to prevent ghost images or residual artifacts on the display.
