Malfunction
Possible reason
Correction
Image is unclear, with
vertical lines and
uneven background.
Calibration required
Perform image calibration
according to Section 9
‘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
wit 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.
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.
