The locking nut of the digital aiming fixing clamp is twisted counterclockwise,and the fixing clamp slot of the digital aiming fixing clamp is corresponded to the pickup guide rail. The bottom of the clamping groove of the fixing clamp is attached to the top surface of the pickup guide rail. The locking nut of the clamping fixture is tightened clockwise to complete the installation of the aiming device.When observing the image of the external environment, if the observed image is not clear, it is necessary to adjust the eyepiece visibility and the focal length of the objective lens. When the eyepiece is adjusted, please refer to the cursor only.Turn the eyepiece hand wheel clockwise or counterclockwise. When the clearest cursor is observed, stop turning. Complete eyepiece visibility adjustment.

Rotate the battery cap counterclockwise, remove the battery cap，let three CR123 batteries toward "+" electrodes position in the battery cartridge（P①）. Then the three negative poles of the battery cover are pointed at the three negative poles of the battery canister (P. 2). The screw teeth of the battery cover and the battery canister are pointed at. The battery cover is pushed slightly. The battery cover is rotated counterclockwise first. When the screw teeth are matched, the battery cover is rotated clockwise until the battery cover is put in place. Twist until tight. It needed to hold the battery cover to reduce friction between the battery cover threads When the battery cover is twisted clockwise.DT-DS8X is Detyl Optoelectronic company with the trend of the time, actively adjust their development to build a high-performance professional digital day-and-night dual-purpose scope, one-button return to zero, self-adaptive electronic dividing (electronic dividing and tracking)；Low illumination adaptability is strong, high image quality, high precision, can be dual-use day and night ，ratio is large, light weight, high cost performance, etc. It also has day and night t camera, videos, GPS, wireless Wi-Fi transmission and other supporting functions, fully meet the needs of modern people "show", is the optimal choice for outdoor hunting.Press the "Power/Menu" button in the operation button to enter the setup menu.

How to install IR illuminator Please refer to 《IR illuminator source instructions》.If the environmental image is not clear enough and the eyepiece vision has been adjusted, the focal length of the objective lens needs to be adjusted. When focusing the objective lens, first select the object to be observed, then clockwise or counter-clockwise rotation of the objective hand wheel, until the clearest image is observed, complete the objective lens focusing.

Mode：The mode menu is used to set up the working mode of the system. Color mode, black and white mode and night vision mode.Click the up and down arrow keys to light the corresponding mode, and then press the "OK" button to confirm the selection. The color mode is used for daytime or strong lighting. The sharpest image can be observed. In the night vision mode, the system improves the sensitivity of the sensor. At the same time, the effective spectral bandwidth is increased to achieve the best night vision effect. Target Calibration: Target calibration is used to correct the deviation between the aiming target and the actual impact point, to correct the installation accuracy of the sight, and to calibrate the environmental error to design a quick correction function. In the shooting training, when the impact point deviates from the position of the target, and the shooting accuracy is insufficient, the target calibration operation is required. When using the target calibration function, first activate the function menu and select the target calibration function. When the yellow cross flashes on the red cross, and the Target calibration icon flashes in upper left corner of the screen, indicating that the target calibration mode has been entered. At this time, the sight cross is lined up with the target and shot. After this while ensuring that the original red dotted line is aligned with the target, then Press the direction key of the operation keyboard to move the flashing yellow cross to the impact point. After pressing the confirmation, the yellow cross will stop flashing and become a red cross. The red cross that is originally aligned with the disappears to complete the target calibration operation. In actual use, to ensure better gun quality, it is recommended to cycle several times to improve the target calibration accuracy. Electronic compass：This menu is used to open and close the azimuth and dip Angle detection of geomagnetic field. Choose to open or closed and confirmed, electronic compass will open or stop working.(the system default electronic compass open). After open the electronic compass, ensure the accuracy of the test, when the line of sight to open, please try to keep the level of the fuselage，DT-DS8X series digital sighting is DETYL Optoelectronic company with the trend of the time, actively adjust their development to build a high-performance professional digital day-and-night dual-purpose sighting, one-button return to zero, self-adaptive electronic dividing (electronic dividing and tracking).When a compass data display for the green (color and black and white mode) or display data for white (night vision mode), suggests that the magnetic field calibration has been completed.  Current magnetic field data displayed in the upper right corner of the screen, in two rows, according to the above row shows the magnetic field orientation, southwest (WE: 320.5 ,320.5 degrees Celsius);The following line shows the tilt Angle, (U up dip 12.3 degrees, 12.3 D 25.1, 25.1 degrees) Recording: This option is used to open or close the machine built-in Mic. The system is off by default.

(Note: Photography is prohibited when the battery voltage is less than 2.5V <ordinary battery > or less than 3.5V < rechargeable lithium battery >)The digital targeting is digital OLED display，The division and adjustment range is +/-25 lattice ，each checks is a pixel. In the vertical and horizontal direction, the adjusting range is exactly the same as that of the adjustment.In actual use, the movement of the dividing cursor can be adjusted by the upper and lower / left and right keys. When enter graduation adjust，short press arrow key for each ，The cursor moves one pixel. （electron multiplying at 1.0X），The cumulative number of moving figures will be displayed on the screen. The number displayed is the offset value of the current cursor position and zero bit.turn up and turn right is‘+’, turn left and turn down is ‘-’，Long press the arrow keys to speed up the movement. For electron multiplying over 1X ，press arrow key for each，The number of mobile digits is the same as that of 1.0X, but the distance of actual movement varies with different rates.but, the position of the cursor corresponding to the target does not vary with the electron multiplication rate.In the normal sight mode, short press the up and down arrow keys can change the electron multiplying rate.("Z: x1.0--Z: x4.0") Up arrow key increases electron multiplication, downward direction key reduces electron multiplication. The rate of change is 0.1 times per time, and the maximum is 4.0 times. Note: in order to ensure the accuracy of aiming, electronic zoom occurs. The crosswise line of sight is automatically corrected according to the magnification and the current position of the crosswise line of sight, but the value of the cursor position remains unchanged.In the photo mode,long press (10sec)the "OK" button to enter the playback mode, in the playback mode. Press the "OK" button to start playback, and press the "OK" button again to stop playing. Short press the up and down arrow keys to turn back and forth. Short click the left and right arrow keys, fast forward and quickly return the current video playback.In the playback mode,long press(10sec) the "OK" button to return to the normal sight mode (video mode).This digital aiming support is used for day and night. During daytime use, the color mode can be used to make the observed targets more real and clear. In order to achieve the best day effect, do not open the lens cover. In order to reduce the effect of strong light on high sensitivity image sensor.Under normal observation mode, press the "Power/Menu" button to enter the menu mode. Click the up / down button to highlight the "mode" menu, and the "OK" button enters the mode setting. Press the up/down direction key again, select the mode you want, confirm the" OK" key, enter the mode you want, and then press Power/Menu to exit the settings. Since the digital targeting uses a highly sensitive CMOS sensor, You can also get very good night vision at night. Night time sensor is more sensitive when used at night. Under the starlight environment, we can achieve the desired sighting effect. Please open the lens cover at night.
