Button&Connection

Bracket installation

Please see the attached installation diagram.

Quick Start

1. Connect the device to the power supply as followed in pic 4 to power on the microscope.
2. Press and hold the Power button (pic 2 #①) until the monitor lights up. (device may switch on automatically when you power it on, and it’s totally normal) *Troubleshooting
When the monitor image stops or froze, please pin the Reset hole (pic 2 #⑩) to reset the device first, then power on the device again. (Reset hole is very tiny, located at the back of the monitor. You may need to use the help of other tools with this process. All settings of the microscope will be back to factory setting after this, but it won’t delete any files saved in the memory card).

How to choose a lens

Lens A：

Focus range: 12mm-320mm，
Magnification: 4.5-180x（with3 times digital zoom)
Applications: observe whole size or part of coins, stones/stamps collect, circuit board observe, etc.

（Pic 5 Use lens A to see a coin）

Steps: In pic 5 it marked out which parts of the microscope are involved in each step.

1. Install and fix lens A to the bottom of the focusing tube.
2. Place the black or white backdrop board to the loophole on the stage, then place the coin on the stage.
3. Bend the two goose-neck spotlights, and make sure the light shines on the coin.
4. Lose the arms locker, located the whole monitor part to the desired height, meanwhile adjusting the height of the mechanical stage, making sure the final object distance is within  12mm to 320 mm. The shorter the object’s distance is, the bigger magnification is.
5. Turn the focusing tube to get a clear image. Turn it clockwise to zoom in and the other way to zoom out.

In order to observe part of the coin, please lower the arm height to shorten the object distance, then turn the focusing tube, to get a clear image.
Steps above can also be applied to observe plants, stones, etc.

Lens B &C：

Lens B: Focus range: 7mm-8mm，Magnification: 390-510x (with3 times digital zoom）
Lens C: Focus range: 3mm-4mm，Magnification: 690-1020x (with3 times digital zoom)
Applications: Microscope slides etc.

（Pic 6 go with Lens B&C）

Steps: In pic 6 it marked out which parts of the microscope are involved in each step.

1. Install and fix the nosepiece set with Lens B&C to the bottom of the focusing tube.
2. Place the translucent backdrop board to the loophole on the stage, and place slides on it.
3. Remove the two USB spotlights.
4. Lose the arms locker, located the whole monitor part to the desired height, meanwhile adjusting the height of the mechanical stage, making sure the final object distance is within 7- 8mm(lens B). The shorter the object’s distance is, the bigger magnification is. Or if you want to zoom in, even more, revolve the nosepiece to lens C and make the object distance within 3-4mm. The shorter the object’s distance is, the bigger magnification is.
5. Turn the focusing tube to get a clear image. Turn it clockwise to zoom in and the other way to zoom out. Or, we recommend users to gently adjust the stage height to get a clear image, this way causes less shake.

*Lens B &C’s magnification is quite big, which requires a short object distance. Meanwhile, any tiny movement or shake of a specimen would be displayed as huge on the monitor, which requires the user to operate very carefully and patiently.

Digital zoom

Press the “up” button on the monitor (pic 2 #③) to apply digital zoom in, and “down” to zoom out( pic 2#④)

Save files to a micro SD card

To save images and videos to a memory card, please insert a card into the TF slot at the back of the monitor before powering on the device.

Attention:

1. TD cards are not included in the standard package. Please purchase it from quality suppliers. We recommend a 10-grade high-speed TF card.
2. The metal strip side of the card faces outward.
3. Push the card deeply into the card slot until you hear a clicking sound. Otherwise, it would bounce back.
4. When the monitor shows “card error” or “card is full”, please format the card first before taking pics. Format steps are: Press and hold button M until it shows a  menu→press M button again to get into the Setting menu→Press up or down button to select→choose” Format” and confirm
5. Do not insert a card while the microscope is working. If you do, the microscope would switch off automatically. And you will have to turn it on again.

In order to take videos, pictures, or playback files we have taken, we need to get into different modes first. The MODE button（pic 4 #②, marked as“M”）can be used to select among three modes, video( ), photo( ), and playback( ).

Record videos

In video mode( ), press the OK button to start recording. Press it again to stop.
It works the same way with the OK button on the remote.
In video mode, the right upper corner of the monitor shows time and “1080FHD”(white font).
Time here shows how long a video the memory card is capable to record, and “1080FHD” shows the current video resolution.

Take photos

In Photo mode( ), press the “OK” button to take pictures.
The button marked as a camera on (pic 2 #⑥), can also take pictures, but only while the camera is recording videos.
* In playback mode the microscope can not take photos or videos

Playback & manage files

Use button M to get into Playback mode, and press “up” or “down” to browse files.
In order to play videos, press OK to play it, OK to pause, and M to stop.

Remote

Freeze: Stop the image on the display, works in video mode, photo mode, and while recording.
Illumination+ & -: exposure compensation from +2.0 to -2.0.
Sharpness up&down: three levels of sharpness: Soft/Normal/Strong. Those two buttons are both used to switch the levels but in different orders.
Contrast up down: the same principle as Sharpness

（Pic 7 Remote）

Settings

In any mode, press and hold the M button until it shows the video/photo/playback menu, press M again, and get into the Setting menu.
For example. In video mode, press and hold the M button, and it would show the video menu in pic 8:
And then, press M again to get into the settings menu as pic 9：

Date/Time Setting
Select “Date/Time” in the setting menu, and press the OK button to get into the time setting. Use the “up” and “down” buttons to select the correct number, OK to confirm, and jump to the next one.  After it’s all done, press M to back to the setting menu.

Save Setting
In order to let the microscope memorize the setting changes, please turn off the microscope by  PRESSING THE POWER BUTTON ON THE MONITOR (press and hold until it switch off).
Setting changes won’t be saved if you switch off the device in other ways.

Troubleshooting

1. The microscope can’t be switched on.
   Please check the connection is exactly as pic 4 shows, the power supply is strong enough (5V 2A & above) and stable. If the device still can be not switched on, please pin the reset hole at the back side of the monitor.

2. Images are not clear.
   Please confirm the illumination work properly, and shine directly to the surface of the specimen.
   Adjust the height of the boom arm, or the secondary bracket lift to change the distance from the lens to the specimen, and turn the focusing tube properly. If the image is still blurry, please clean the bottom of the lens using a piece of a clean and soft cloth.

3. Setting changes can’t be memorized.
   After changing settings, press and hold the button on the monitor to switch off the device. DO NOT cut off the power supply directly or use the dimmer cable to switch off the device.

4. The microscope reboots repeatedly.
   Please check if the cable connection is firm and if the power supply is stable and strong enough.
   Please check your power adapter is high-quality 5V 2A.

5. It shows “card error” or “card is full” after inserting the memory card into the device.
   Please format the card after inserting it into the device. (Format steps refer to chapter “Save files to micro SD card”)
