Description of Battery Installation
Application of Color Palette
Image effects out of photo taken by six kinds of color palettes:
Prompt: When this product lies idle for long, it shall be charged at
least every three months to prevent irreversible loss of capacity due
to too low battery power arising from its own discharge as it is kept
too long.
The palette menu can change the pseudo color of the infrared
thermal image, and provides 6 palettes: rainbow, hot metal, white
heat, black heat, yellow saturation and bird watching mode.
Choosing an appropriate palette can better display the details of the
target object. For rainbow, the hot metal palette focuses on displaying
colors, which is very suitable for high thermal contrast and is used to
improve the color contrast between high and low temperatures.
However, the white hot palette provides uniform linear colors.
1. Open the battery cover: Unscrew the battery cover counterclock-
wise.
2.Install the lithium battery: Put the battery into the battery
compartment with the negative pole of the battery facing outward.
3. Install the battery cover: Tighten the battery cover clockwise.

Application of Image Detail Mode
Calibration and Application of Cursors
Precautions for formatting an SD card
2. During actual use, visually check the prey distance, for example,
about 10m, and extract the cursor calibrated for 10m. At this time, the
center position of the cursor is the center position of the prey. Aim
directly according to the cursor of C8 product.
3. Visually check the prey distance, for example, about 100m, and
extract the cursor calibrated for 100m. At this time, the center position
of the cursor is the center position of the prey. Aim directly according
to the cursor of C8 product.
When the SD card inside the machine is connected to the computer
through USB to format the SD card, the SD card needs to be re-iden-
tified when using the machine for the first time. This process takes
3~5 minutes, during which all keys cannot be operated. This is a
normal appearance.
1. Only one of the image edges or image details can be selected for
the adjustment to image quality.
2. If you want the image edge to be clearer and more stereoscopic,
then select the image edge before selecting the corresponding value
on the image detail value to make the image edge clear.
3. If you want the overall image quality to be clearer, select details,
and then select the corresponding value on the image detail value to
make the overall image quality clear.
1. Before use for the first time, mount the C8 product onto the
equipment. As customers maintain a variety of equipment, it is
necessary to complete the matched setting for the C8 product and
the equipment. At different distances, the landing point and the C8
cursor must be calibrated consistently. Select the landing point
distance (10m, 30m, 60m, 100m, 300m, 600m or user-defined
distance). Perform cursor calibration for each item. Please refer to
the previous operation for cursor calibration.
Note: As the target distances are different and the coordinates of the
cursor are not located at the same point, so it is necessary to select
the calibration distance according to the distance so as to achieve
the purpose that the landing point coincides with the C8 cursor and
aims at the target more accurately.
