Malfunction
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.
