The device features a built-in 18650 rechargeable lithium polymer battery and supports USB interface charging.
4.2 Inserting a Micro SD Card
A Micro SD card (up to 128GB, not included) is required to save photos and videos.
- Locate the TF card slot on the monocular.
- Carefully insert the Micro SD card into the slot until it clicks into place. Ensure the card is oriented correctly.
- To remove, gently press the card until it springs out.
5. Operation
5.1 Powering On/Off
- To power on, press and hold the ON/OFF button until the display illuminates.
- To power off, press and hold the ON/OFF button until the display turns off.
- The device features an automatic shutdown function to conserve battery if no operation is detected for a period.
5.2 Focusing
Adjust the focus for a clear view of your target.
- While looking through the eyepiece, rotate the Focus Wheel (located near the objective lens) until the image on the display is sharp.
5.3 Zoom Function
The monocular offers 6x optical magnification and up to 8x digital zoom.
- Use the Zoom + button to increase digital magnification.
- Use the Zoom - button to decrease digital magnification.

Figure 5.1: Magnification. This image illustrates the 6X optical magnification and 8X digital zoom capabilities of the PUSOKEI Night Vision Monocular, showing how a distant object (a lion) can be brought into closer view on the display.
5.4 Night Vision and Infrared Illumination
For clear viewing in low light or complete darkness, activate the infrared illuminator.
- Press the IR Light button to cycle through infrared illumination levels (e.g., Level 1, Level 2, Level 3, Off).
- Higher IR levels provide greater visibility in darker conditions but may consume more battery.

Figure 5.2: Infrared Levels. This image demonstrates the three levels of infrared illumination available on the monocular. It shows how increasing the infrared gear adjustment leads to a longer observation distance and higher definition in dark environments, with example images of a lion at different IR levels.

Figure 5.3: Day and Night Visibility. This image compares the monocular's performance during the day (color image) and at night (monochrome image with IR activated). It highlights the clear viewing capability at 250-300 meters using the 3W/850nm infrared illuminator.
5.5 Taking Photos and Recording Videos
The monocular supports real-time photography and video recording (without sound recording).
- Press the Menu/Mode button to switch between photo and video modes. The current mode will be indicated on the display.
- In photo mode, press the OK button to take a picture.
- In video mode, press the OK button to start recording. Press it again to stop recording.
- Ensure a Micro SD card is inserted to save your media.
5.6 Playback and Data Transfer
View your captured media directly on the device or transfer it to a computer.
- Use the Menu/Mode button to enter playback mode.
- Navigate through your photos and videos using the zoom buttons or other directional controls (if available).
