Usage Features
- Quick Start: Connect to power, press and hold the power button until the monitor lights up. The device may switch on automatically upon power connection.
- Lens Selection: The manual provides detailed instructions for installing and using each of the three lenses (L, A, D), including recommended working distances and applications.
- Lens L (90mm-300mm working distance): Focus is achieved by adjusting the monitor height via the Arm V-locker and then fine-tuning with the focusing tube.
- Lens A (12mm-320mm working distance): Similar to Lens L, adjust monitor height and then use the focusing tube for clear images. For observing parts of objects, lower the arm height to shorten the object distance.
- Lens D (4mm-5mm working distance): Due to its high magnification and short working distance, it's recommended to adjust the height of the secondary bracket for precise focusing. Requires careful and patient operation due to high sensitivity to movement.
- Illumination: Goose-neck spot lights are provided for general illumination with Lens A and L. For Lens D, a slide holder with its own power source is used for proper illumination.
- Digital Zoom: Use the "up" and "down" buttons on the monitor (or remote) to digitally zoom in and out.
- Recording and Capturing:
- Video Recording: In video mode, press the "OK" button on the monitor or remote to start/stop recording.
- Photo Capture: In photo mode, press the "OK" button on the monitor or the camera button on the remote to take pictures. The camera button on the remote only works while recording videos.
- File Management:
- Micro-SD Card: Insert a micro-SD card (up to 32GB, Class 10 recommended) into the TF slot before powering on to save images and videos.
- Formatting: If "card error" or "card is full" appears, format the card via the Settings menu (Menu -> Setting menu -> Format).
- Playback: Enter Playback mode using the "M" button, then use "up" or "down" to browse files. Press "OK" to play/pause videos, and "M" to stop.
- Settings: Access settings by pressing and holding the "M" button until the video/photo/playback menu appears, then press "M" again to enter the Setting menu. Options include Resolution, Loop Recording, Exposure, Record Audio, Date Stamp, Date/Time, Language, Frequency, Format, Default Setting, and Version.
- Date/Time Setting: Select "Date/Time" in the settings menu, press "OK", use "up"/"down" to select numbers, and "OK" to confirm. Press "M" to exit.
- Remote Control: The remote offers functions such as Menu, Mode, Zoom, Brightness, OK/Start Record, 50/60Hz, Sharpness, Contrast, Inverse, Black&white, Cross line, Lock/unlock file, Default set, and Image rotate.
- Freeze: Stops the image on display in video/photo/recording modes.
- Illumination+/-: Adjusts exposure compensation from +2.0 to -2.0.
- Sharpness: Three levels: Soft/Normal/Strong.
- Contrast: Similar to Sharpness, adjusts contrast levels.
- Inverse/Black&white: Toggles image display modes.
- Image Rotate: Rotates the image.
Maintenance Features
- Safety Precautions:
- Read the manual carefully to avoid permanent damage.
- Contains tiny, non-edible parts; supervise children and teens.
- Not for outdoor use; not waterproof.
- Keep in a safe, clean, dry environment, away from oil, gas, water, and corrosive potions.
- Not for medical use.
- Cleaning:
- Lens: If the image is blurry, cut power, wipe the lens with a soft cloth moistened with alcohol, and ensure it's dry before powering on.
- Monitor: The screen is fragile. Clean with a soft, dry material. Do not drop, hard press, or expose to sharp objects. Only wipe the INSULATED part of the monitor.
- Troubleshooting:
- Monitor Stops/Freezes: Pin the Reset hole (pic 2 #⑩) at the back of the monitor to reset. This will revert all settings to factory defaults but will not delete saved files.
- Device Not Switching On: Check power connection (5V 2A and above) and stability. If issues persist, try resetting the device.
- Unclear Images: Ensure proper illumination, adjust boom arm/secondary bracket height, and turn the focusing tube. If still blurry, clean the lens.
- Settings Not Saved: To save settings, turn off the microscope by pressing and holding the POWER BUTTON ON THE MONITOR. Do not cut off power or use the dimmer cable to switch off.
- Microscope Reboots Repeatedly: Check cable connection firmness and power supply stability (high-quality 5V 2A adapter).
- "Card Error" or "Card is Full": Format the micro-SD card as described in the "Save files to micro SD card" section.
