Possible reason

Correction

Image is unclear, with vertical lines and uneven background.

Calibration required

Perform image calibration according to Section ‘Calibrationʼ of the Manual.

The image is too dark.

Low brightness level set.

Adjust display brightness.

Colored lines appeared on display or the image has disappeared.

The device was exposed to static electricity during operation.

After exposure to static electricity, the device may either reboot automatically or require turning off and on again.

Poor image quality/ reduced detection distance

These problems may occur during observation in difﬁcult weather conditions(snow, rain, fog, etc. ).

Smartphone or tablet cannot be connected to the device

The device password has been changed.

Delete the network and reconnect using the device password

The device is in an area with a large number of Wi-Fi networks that may cause interference.

To ensure stable Wi-Fi operation, relocate the device to an area with fewer Wi-Fi networks, or into an area with none.

Malfunction

Possible reason

Correction

Wi-Fi signal non existent or interrupted

The device is outside the area of Wi-Fi coverage. There are obstacles between the device and the receiver (e.g. concrete walls.)

Relocate the device into direct line of sight of the Wi-Fi signal.

When used in low-temperature conditions, the image quality of the surroundings is worse than in positive temperature conditions.

In positive temperature conditions, objects being observed (surroundings and background) heat up differently because of thermal conductivity, thereby generating a high-temperature contrast. Accordingly, the image quality produced by the device will be higher.In low-temperature conditions, objects being observed (background) do, as a rule, cool down to roughly the same temperature because of which temperature contrast is substantially reduced and the image quality (detail) is poorer. This is a feature of thermal imaging devices.
