5. Setup
5.1. Charging the Device
Before first use, fully charge the endoscope unit using the provided USB charging cable and a standard 5V/1A USB power adapter (not included). The charging indicator will show the charging status.
5.2. Inserting an SD Card
To save photos and videos, insert a MicroSD card (Class 10, 32GB-128GB recommended, not included) into the SD card slot on the side of the monitor unit. Ensure the card is inserted correctly until it clicks into place.
5.3. Attaching Accessories
The accessory kit includes a hook, magnet, and side mirror. These can be screwed onto the tip of the camera head for specific tasks, such as retrieving small objects or viewing at a 90-degree angle (though the side camera often negates the need for a side mirror attachment).

6. Operating Instructions
6.1. Power On/Off
Press and hold the power button (usually marked with a power symbol) for a few seconds to turn the device on or off.
6.2. Adjusting LED Brightness
The camera head features multiple LED lights. Press the LED brightness button (often indicated by a light bulb icon) to cycle through 3 levels of brightness or turn the lights off. This helps illuminate dark inspection areas.

6.3. Switching Between Front and Side Cameras
The DS620 is equipped with a dual-lens system. Press the camera switch button (often labeled with a camera icon or 'M') to toggle between the front-facing camera and the side-facing camera. This allows for different viewing angles without repositioning the probe.

6.4. Rotating the Screen
To adjust the orientation of the image on the monitor, press the screen rotation button (often indicated by a circular arrow). The image can be rotated 180 degrees for optimal viewing.
6.5. Capturing Photos and Videos
- To take a photo: Press the photo capture button (usually a camera icon) once. The image will be saved to the inserted MicroSD card.
- To record a video: Press the video record button (usually a video camera icon) once to start recording. Press it again to stop recording. The video will be saved to the MicroSD card.
6.6. Viewing Media
Enter playback mode by pressing the playback button (often a play icon). Use the navigation buttons to browse through your captured photos and videos. Press the playback button again to exit playback mode.
6.7. Connecting to a PC
To transfer files, connect the endoscope unit to a computer using the USB charging cable. The device will appear as a removable storage device, allowing you to access the contents of the MicroSD card.
7. Maintenance
7.1. Cleaning the Camera Lens and Cable
After each use, gently wipe the camera lens with a soft, dry cloth to remove any debris or moisture. The waterproof camera cable can be cleaned with a damp cloth. Ensure the cable is dry before storage.
7.2. Storage
Store the endoscope in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided drawstring bag to protect the device from dust and scratches.
7.3. Battery Care
To prolong battery life, avoid fully discharging the device frequently. If storing for an extended period, charge the battery to approximately 50% every three months.

8. Troubleshooting
- Device does not power on: Ensure the battery is charged. Connect to a power source and try again.
- No image on screen: Check if the camera cable is securely connected to the monitor unit.
- Image is blurry or dark: Adjust the LED brightness. Clean the camera lens. Ensure the object is within the camera's focal range (3-10 cm for front, 2-6 cm for side).
- Cannot save photos/videos: Ensure a compatible MicroSD card is inserted correctly and has sufficient free space. Format the SD card if necessary (refer to device settings).
- Device freezes: Press and hold the power button for 10 seconds to force a restart.
