6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Camera does not power on | Low or depleted battery | Charge the battery fully. |
| Image is blurry or out of focus | Incorrect focus adjustment | Rotate the lens ring to adjust focus. |
| Camera freezes or becomes unresponsive | Software issue or temporary glitch | Perform a soft reset by holding the power button for 10-15 seconds. If issue persists, contact support. |
| "Ghost images" or double images appear | Sensor calibration issue | This may indicate a hardware issue. Contact FLIR customer support for assistance. |
| Cannot save images to SD card | SD card full, corrupted, or improperly inserted | Check SD card insertion. Try a different SD card. Format the SD card (this will erase all data). |
