The device does not turn on
Possible cause
Battery Pack is discharged.
Solution
Charge the Battery Pack.
The device does not operate from an external power source
Possible cause
The USB cable is damaged.
Solution
Replace the USB cable.
Possible cause
The external power supply is discharged.
Solution
Charge the external power supply (if necessary).
The image is blurry, with vertical stripes or an uneven background
Possible cause
Calibration is required.
Solution
Perform the calibration according to Calibration Mode section.
Black screen after calibration
Solution
If the image does not clear after calibration, you need to recalibrate.
Poor quality image. There is noise or ghost images of previous scenes or objects
Possible cause
Manual calibration has been performed with the lens cover open.
Solution
Check the Calibration Mode, close the lens cover and calibrate the device.
The image is too dark
Possible cause
Brightness or contrast level is too low.
Solution
Adjust the brightness or contrast level in the Quick Menu.
Color bars appear on the display or the image disappears
Possible cause
The device was exposed to static electricity during operation.
Solution
After exposure to static electricity, the device may either reboot automatically or require turning off and on again.
The image of the object being observed is missing
Possible cause
You are looking through glass.
Solution
Remove the glass or change the viewing position to avoid it.
Poor image quality / Detection range reduced
Possible cause
These problems may occur during observation in adverse weather conditions (snow, rain, fog, etc.).
Smartphone or tablet PC cannot be connected to the device
Possible cause
Device password has been changed.
Solution
Delete the network and connect again using the password saved in the device.
Possible cause
The device is in an area with too many Wi-Fi networks that may be causing signal interference.
Solution
To ensure a stable Wi-Fi connection, relocate the device to an area with fewer or no Wi-Fi networks.
Possible cause
The device has a 5 GHz network enabled, but the smartphone only supports 2.4 GHz.
Solution
Switch the device’s Wi-Fi bandwidth to 2.4 GHz.
Wi-Fi signal is missing or interrupted
Possible cause
Smartphone or tablet is out of range of a strong Wi-Fi signal. There are obstacles between the device and the smartphone or tablet (e.g., concrete walls).
Solution
Relocate smartphone or tablet into the Wi-Fi signal line of sight.
The image quality during the device operation at below zero temperatures is worse than at positive temperatures
Possible cause
Because of variations in thermal conductivity, objects (surrounding environment, background) under observation become warm more quickly at above-zero temperatures, which allows higher temperature contrast, so the quality of the image produced by a thermal imager will be better.
At low operating temperatures, objects under observation (background) normally cool down to roughly identical temperatures, which leads to reduced temperature contrast and to image quality (precision) degradation. This is normal for thermal imaging devices.
