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 20 seconds before switching the
device on again.
APPLICATION
The monocular 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.

To be able to use the thermal imaging
monocular with other optical devices
you may need a suitable adapter.
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 fixe 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.
OPERATION & QUICK SETTINGS
Use as stand-alone device
With the optional eyepiece (16) 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).

EN
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).
Changing colour palettes
Hot black / hot white colours
are usual default setting. To change these
settings, press and hold the INVERT
button (7) for 3-5 seconds until the PLx
display appears (where “х” - the number
of the colour group, from 0 to 9). The
desired colour can now be selected by
pressing the INVERT button (7) again. To
save this setting, press the MENU
controller (4). Note that the device
settings do not change after switching
the device off.
Colour inversion
Briefly press the INVERT button (7) to
select the required image polarity: e.g.
“hot black” or “hot white”. All existing
colours can be inverted. The selected
polarity is shown on the display for a
moment (normal) or (inverted).

Detail Enchancement / DE) 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 adjust the brightness of the display
(BR), choose the suitable value from 1 to
30, turn the MENU controller (4).

11

(values from 0 to 7), turn the MENU
controller (4) in the selected (DE) mode.
To set the optimal sensor performance
(GN), choose the suitable value from -10
to +10 by turning the MENU controller
(4).
An alternative way to make settings is to
use the Quick settings table. To enter it,
shortly press TABLE button (9).
By pressing and turning the MENU

settings described above can be saved
along with the selected Colour palette
and Colour polarity as individual unser
profiles.
The TFA device already has three pre-
installed profiles: Fix 1 Woods, Fix 2 City,
Fix 3 Mountains. If one of these profiles
is selected, the difined individual settings
made previously are no longer available.

User 3) can be customized. Press and
turn the MENU controller (4) to access
the corresponding positions and sub-
positions of the main menu. The selected
settings or their changes are saved
automatically in the respective profile.

are displayed when you first call up the
"Colour palette" menu item. Note that the
settings of the selected palette are saved
after the device is switched off.
Change of Colour palette
(Palette on button USER)

In this way, you can quickly select a
different colour palette than defined in
the basic setting (Colour Palette).
Thermal image gain
Here you can determine the performance
of the thermal imaging sensor. This
setting process is also described in detail
in the operation & quick settings chapter.
Display brightness
The brightness setting of the micro
display can be made in this menu item.
This setting process is also described in
detail in the operation & quick settings
chapter.
Thermal sensitivity
The settings for the sensitivity of the
thermal sensor can be adjusted here. To
set the optimal sensor sensitivity (values
from 40 to 80), turn the MENU controller
(4).
Image Detail Enhancement (IDE)
Settings for increasing the general image
quality and detail. This setting process is
also described in detail in the operation
& quick settings chapter.
Super contrast display mode

15
EN
Increases the contrast and image quality,
especially with insignificant temperature
differences for observed objects or
backgrounds.
USB transfer mode
Enables the copying and deletion of
video files from the built-in memory
card. If you select this menu item and the
words "Connection is being established
..." appears on the screen, the device will
soon be visible as a flash drive.
Video recording mode
You can choose either a normal start or a
quick start for video recording.
In normal start mode, the video
recording starts with a slight delay (up to
10 seconds) after the "REС" button (8) is
pressed to switch on the corresponding
module and load the software.
In the quick start, modules and software
loading are activated just after the
pressing the "REС" button. Videos are
recorded up to 5 seconds faster after the
REC button is pressed.
The following indicators are visible in
the status bar during video recording:

EN
EN
REC (blinking) - Recording module active
REC 00:00:00 - ready to record
REC 00:01:20 - recording
REC Saving - internal storaging running.
Note, that the betterie consumption is
greater in the video recording mode as
well as during the quick start.
To reduce power consumption, you can
press and hold the “REC” button (8) for a
few seconds and turn off the video
module.
After that, it takes some time for to start
recording video again, similar as during
the normal start mode.
Please note that video recording is not
possible if the internal or external power
sources are not sufficiently charged. Due
to that reason, the recording also can
stop automatically.
Date and time stamp
Using the date and time stamp, the date
and time of the video recording can be
displayed on the internal memory card.
Adaptation to the ambient
temperature:

17
EN
For better contrast when observing the
objects ans surroundings with very
similar thermal patterns, the thermal
imaging sensor can be adapted to the
average ambient temperature in this
mode.
Automatic pixel correction
After an automatic correction of
defective pixels, press and hold the
MENU controller (4) to save changes or
briefly press the MENU controller (4) to
cancel the changes.
Please note, that the lens must be closed
by the device during the pixel correction!
Manual pixel correction
In this mode, individual defective pixels
or pixel groups can be corrected
manually. Please note that the correction
of a pixel group from its edges to the
center must be done by gradually
reducing the radius of the group.
By turning the MENU controller (4), the
marking cross can be moved over the
field of view (note: with constant
rotation, the increment of the shift
increases!).
The coordinate axis of the cross
movement can be changed by briefly

18
EN
pressing the MENU controller (4). After
the cursor is positioned as precisely as
possible over the defective pixel, briefly
press the ON / OFF button (1). The pixel
then changes colour.
Repeat the process with other defective
pixels if necessary. To save the changes,
press and hold the MENU controller (4).
