1. Overview
Xmini is a multifunction thermal imager with built-in VOx uncooled infrared focal plane array
detector. Xmini has small size, light weight, high performance, various purpose and many other
strengths. Moreover, a variety of sensors are equipped and it not only can be used as Monocular
hand-held thermal imager or portable infrared thermal image sight but also can be used as wearable
device when installed on the helmet. Xmini can be widely used in investigation, security, search
and rescue, outdoor sports and other application fields.

5. Operation Functions
The related function such as switch, peripheral, menu and other functions can be implemented
through operating the rotary encoder. And all the operations can exit through pressing the encoder
for 3 seconds.
5.1 Switching on/off
▶"$#The product will be switched on and display start up logo after pressing encoder for 3
seconds.
The status indicator icon is displayed in the upper left corner of the image and the battery
power icon is displayed in the upper right corner. As shown in figure 5-1 of normal display.
▶Switching off the encoder by putting the lens straight down and pressing the encoder for 3
seconds.
5.2 Electronic Magnification
▶When there is no menu, rotating the encoder can zoom image. The image will be zoomed
in with clockwise rotation and zoomed out with anticlockwise rotation between 1.0 and 4.0;
▶Slowly rotating the encoder, the magnification is adjusted with a step of 0.1 and rapid
rotation is amplified by x 1.0, x 2.0, x 3.0 and x 4.0;
▶The current magnification is displayed on the upper left icon;
▶The center of image is enlarged when there is no reticle and the center image of reticle is
enlarged when the reticle is displayed.

5.3 Context Menu
When there is no menu, short press the encoder to call up the context menu, as shown in figure
5-2. The four functions clockwise are image correction, image mode, brightness and laser. Rotating
encoder can achieve switch function and short press encode can start up the executive function. If
there is no operation within 30 seconds, it will exit the context menu automatically. Or it will exit
after pressing the encoder for 3 seconds.
◆Image correction：Short press the encoder to perform the background correction while the
lens is facing down and other orientations to perform shutter correction.
◆Image mode：W(white hot)、B(black hot)、R(red hot)、C(pseudo color).
◆Brightness：Screen brightness adjustment. There are 1~9 levels can be adjusted.
◆Laser：Turn on/off the laser designation.

5.4 Advanced Menu
When there is no menu, long press the rotary encoder for 3 seconds to call up the advanced
menu (when long press the encoder, don’t let lens vertically down, otherwise Xmini will be
shutdown). The advanced menu includes five functions which are Device, Function, Reticle,
Calibration and Setting. Each function contains several options and corresponding options item pop
out when select a certain function, as shown in figure 5-3.
