1 Safety
This is a general safety guide, covering many models of thermal imaging cameras
from a common product line, so some functions and descriptions in this chapter may
not apply to specific models.
Before you proceed to operate the camera, acquaint yourself thoroughly with the present manual and
observe the safety regulations and specifications defined by the manufacturer.
Any application that differs from those specified in the present manual may result in a damage
to the device and constitute a source of danger for the user.
The camera must not be used in rooms where special conditions are present e.g. fire and ex-
plosion risk.
It is forbidden to use damaged or malfunctioning camera and is partially or fully out of order,
In case the camera is not used for a long time, its battery should be removed. Leaving the bat-
tery inside the device may cause the battery to leak and damage the camera.
It is not allowed to use the camera with half-closed or opened battery cover and do not use any
other power adapter than the one supplied with the camera.
Repairs may be carried out only by an authorized service point.
This equipment has been tested and found to comply with the limits for a Class A digital device, pur-
suant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance
with the instruction manual, may cause harmful interference to radio communications. However, there
is no guarantee that interference will not occur with a particular installation. If the device causes
harmful interference to radio or television reception, which can be determined by turning the device
off and on, the user should try to correct the interference by using one of the following means:
Changing the direction or position of the receiving antenna.
Increase the separation between the device and the receiver.
Connect the equipment to a socket on a circuit different from that to which the receiver is con-
nected.
Consult the dealer or an experienced radio / TV technician for help.
The device has been assessed as meeting the general requirements for immunity to exposure
to radio-frequency (RF) radiation.
The following precautions must be adhered to at all times:
Keep the camera steady during operation, to prevent rapid shocks.
Do not use the camera in ambient temperatures exceeding its operation and storage tempera-
ture ranges.
Do not direct the camera toward very high intensity radiation sources such as the sun, lasers or
welding arcs etc.
Do not expose the camera to dust and moisture. When operating the device near water, ensure
that it is adequately guarded against splashes. Cover the lens when the device is not used.
When the camera is not in use or is to be transported, ensure that the unit and its accessories
are stored in the protective carry case.
Do not obstruct the speaker holes in the camera’s body.

Do not throw, knock or shake intensely the camera and its components in order to avoid the
damage.
Do not attempt to open the imager's body, as this action will void the warranty.
Keep the SD memory card for the exclusive use of the camera.
Do not use the unit in an environment where its working temperature is exceeded to avoid pos-
sible damage.
Do not use solvents or similar types of liquids on the unit and cables to avoid possible damage.
The camera is powered by Lithium-ion battery, therefore users must strictly adhere to the fol-
lowing guidelines to ensure safe use:
oNever attempt to open or disassemble the battery,
oDo not place the battery in a hot temperature environment or near hot objects,
odo not short-circuit the battery terminals,
oDo not place the battery in a damp environment or in water,
oIn case of leakage of liquid from the battery that makes direct contact with eyes, immedi-
ately rinse your eyes with clean water and seek appropriate medical attention,
ocharge the battery according to the instructions and abide the charging stages and precau-
tions; Incorrect charging may overheat or damage the battery and may cause injury,
oremove the battery if the device will not be used for a long time.
Clean the device as described below:
onon-optical surfaces: use soft and moist cloth to clean non-optical surfaces of the thermal
imager;
ooptical surfaces: Avoid staining the optical lens surface while using the thermal imager, es-
pecially avoid touching the lens with your hands, as sweat may leave marks on the lens
and corrode optical coatings on the lens surface. When the optical surface of the lens is
fouled, wipe it with a special lens cleaning paper;
The battery can be recharged many times. However, the battery is a delicate part. If the
operating time of the device is reduced significantly, please replace the battery with a new,
original one provided by the manufacturer.
During imager operation its housing temperature increases and it’s a normal phenomenon.
When it's hot, stop charging the battery and move the device into a cool place. Avoid tou-
ching hot surfaces for prolonged period of time.
For charging the device, it is recommended to use original batteries and charging cables
provided by the manufacturer.
Battery charge time depends on the temperature and the discharge level.
Low battery level is indicated by the camera.
When the battery level is too low, the thermal imager will turn off automatically.
If the device does not respond to the power button pressing, the battery is exhausted and
the device can only be started after charging with the original charger for more than 10
minutes.
When the battery is charging, the charging indicator light on the side of the camera lights
up red.
When the battery is fully charged, the charging indicator light changes from red to green,
indicating that no further charging is required.

WARNING
Laser locator installed in the camera may be dangerous to eyes, in case of direct
contact!
DO NOT DIRECTED THE LASER BEAM TOWARDS OTHER PERSONS OR
ANIMALS!
Please note that the laser beam may reflect off shiny surfaces.
NOTE!
KT series thermal imagers have no parts that could be repaired or modified by its
user. Never attempt to dismantle or modify the device. Opening up the unit invali-
dates the warranty.
Use only standard and additional accessories, listed in "Equipment" section. Using
other accessories does not ensure proper operation of the camera and may cause
its damage.
Due to the continuous development of the device, the design of the display and its
certain features may be slightly different than presented in this manual..
For proper battery performance, charge unused batteries every 3 months. If you do
not use the unit for a long time, remove the batteries and store them separately.

2 Description of the camera
Thank you for purchasing our thermal imager.
KT series imagers are modern, high-quality, easy and safe to use measuring devices. They allow to
capture high-quality, fully radiometric thermal images. This product combines high-quality measure-
ment parameters with an innovative and intuitive interface, based on a new operating system, to cre-
ate an intelligent solution in the field of thermal imaging.
The camera operation, with a large, touch screen is very easy. In addition to standard modes like IR
(infrared), visual and PIP (picture in picture), the camera has a new mode for mixing images, over-
lapping and blending outlines of the visual image on the infrared image. User can take and store stat-
ic images or record and save video clips. The available range of software tools allows an image anal-
ysis on the go, also in the live mode. Each infrared image can have a text note, voice annotation
and/or sketch attached to it. On site reports are possible with the embedded PDF report editor. The
camera provides a number of ways to connect to external devices, both wired (USB, HDMI) and wire-
lessly (Wi-Fi).
Please acquaint yourself with this manual to improve your daily work with the device, and to avoid
measuring errors and prevent possible problems related to operation of the imager.
The camera operation and available options may vary, depending on the camera
model. This manual describes the operation based on the highest specs model
available.
