IMPORTANT NOTES & WARNINGS
Never look with the device in the sun or other
intense heat sources, this can lead to damage of
the sensor!
Protect the device from strong side impacts.
Only use optical cleaning cloths when
cleaning glass surfaces.
Remove the batteries to store.
Use batteries and power supplies from
reputable manufacturers.
Wait 3-5 seconds before switching the device
on again.
APPLICATION
The device is designed to observe moving and
immovable objects in different lighting
conditions as well as limited visibility (fog, dust,
etc.).
The device can be used to display locations and
objects of a temperature different from the
environment. It can e.g. used by guardians,
tourists, hunters, fishermen to explore the
terrain, detection and recognition of different
objects and nature observation.
Please note that the use of the device on a
riflescope is restricted in many European
countries without a special permit. Follow state
laws and applicable legislation!

OPERATION & QUICK SETTINGS
Insert the batteries according to the polarity
shown on the battery compartment (5) and
remove the lens cover (2). Switch on the device
by pressing the ON / OFF button (1). The control
indicator (6) now lights up red. The complete
switching on process should not take longer
than 3-5 seconds. The device is completely
ready for operation after the following view
appears.
If the light indicator does not light up or blinking
and the battery status indicator at the bottom
right of the display is not visible or blinking, the
battery charging or charging of external power
sources must be checked.
----------------------
If the power supply taking place via the USB type
C slot, a USB symbol will be displayed instead of
the battery status sign.
----------------------
While using rechargeable elements instead of
batteries, the battery indicator changes its color
to blue.
----------------------
The image on display can be warm to cold tones;
it is not a defect.
To be able to use the thermal imaging
monocular with other optical devices you may
need a suitable adapter.

EN
8
First, loosen the locking screw on the locking
ring (15) on the ocular side of the device with
the enclosed key. Now screw the adapter (16)
on, place it into desired position and fix it with
the locking ring (16). The locking ring have to
be tightened again after that.
After using the device, close the objective with
the lens rubber cover (2) and switch off the
device by pressing the ON/OFF button.
Use as stand-alone device
With the optional eyepiece (14) you can use
your TFA device as an independent observation
device. First, attach an eyepiece to the ocular
part of the device with a suitable adaptor. After
that, adjust the sharpness of all display
indications with the eyepiece (14). Then point
the device at the object to be observed and
adjust the sharpness of it with the focusing knob
(3).
Choose in Main menu (for enter in Main menu
press and hold MENU button): Main menu –
Type of device –Monocular.
Use with day optics
To be able to use your TFA device with other
(day) optics, the suitable adapter is required
with inside diameter corresponding to the
outside diameter of the day optics’ objective. As
described above, firsts the display sharpness
has to be adjusted with daytime optics. After
that, the observed objects’ sharpness to be
adjusted with the focusing knob (3).
Choose in Main menu (for enter in Main menu
press and hold MENU button): Main menu –
Type of device –Clip-on.

Color inversion
Hot black / hot white colours are usual default
setting.
Briefly press the INVERT button (7) to select the
required image polarity: e.g. “hot black”or “hot
white”.
For change the palette please use suited chapter
in main menu (Main menu –Color palette) or
use the programmable button USER (for more
details see p. Main menu)
All existing colours palettes can be inverted. The
selected polarity is shown on the display for a
moment (normal) or (inverted).
Quick settings: display & thermal sensor
With the MENU controller (4) you can adjust the
brightness of the display (Display Brightness /
BR), the sensor sensitivity (Thermal sensitivity /
SN), digital image enhancement (Image Detail
Enchancement / IDE) and sensor performance
level (Thermal image gain / GN).
The individual setting modes can be seen on the
display as shortcuts (here e.g. GAIN):
To set the optimal sensor performance (GN),
choose the suitable value from -10 to +10 by
turn the MENU controller (4).
To adjust the brightness of the display, short
press MENU controller (4) for selecting BR

EN

adjustment mode and choose the suitable value
from 1 to 30 by turn the MENU controller (4).
To set the optimal sensor sensitivity (values
from 40 to 80) short press MENU controller (4)
for selecting SN adjustment mode and turn the
MENU controller (4) for optimal result.
To set the optimal level of digital image
enhancement (values from 0 to 7), press the
MENU controller (4) until (IDE) mode appears
on the screen then rotate controller (4) to set
optimal level.
For repeatability control, the OSD table can be
called up by pressing TABLE button (9) briefly
every time you re-attach your TFA device, the
adapter opened and device moved slightly so,
that the four-field matrix lies on the marking of
the day optics. The adapter must then be closed
up again.
This control procedure is usually not necessary
though, with a good adapter the devices are
repeatable.

ADJUSTMENT
Make sure that your day optic is sighted in at
100 m.
• Point your day optic exactly at a relatively
small warm object (e.g. a hand warmer) at a
distance of approx. 100 m and fix it solidly in
this position e.g. in a vice.
• Mount the TFA device on the objective of your
day optics using a high-quality clamp adapter.
• Switch on the TFA device, open the objective
cover and look through the whole system again.
• If the observed object is no longer in the centre
of the reticle, it must be “moved”back there.
• To do so, press and hold the MENU controller
(4) and select the "Image position correction"
in the main menu (make sure that Clip-on mode
has been enabled first).
• First move the object along the X-axis
(horizontal directional arrows) by turning the
MENU controller (4) and confirm the
correction.

EN
20
• Now move the object along the Y-axis (vertical
directional arrows) in the same way and
confirm the correction.
• Go back to the main menu (press and hold the
MENU controller (4) and select the menu line
"Table position correction".
• In the same way as described above, move the
square table that appears so, that its centre lies
exactly above the object/reticle.
• Confirm and exit the main menu.
For repeatability control, the quick settings table
can be called up briefly every time you re-attach
your TFA device, the adapter opened and device
moved slightly so, that the four-field matrix lies
on the marking of the day optics. The adapter
must then be closed up again. This control
procedure is usually not necessary though, with a
good adapter the devices are repeatable.
ACCESSOIRES
The device offers the possibility of connecting
an external power source with 9.5-14.5 V with a
JACK 2.1 connector (12).
It is also possible to supply the device with an
external power source via the USB type C
connector (11) with a voltage of 5 V.
