How to choose lens
Lens L：
Working distance：90mm-300mm，
Magnification：15-60x（with3 times digital zoom)
Applications：circuit board observe, watch repair etc.

7
（pic 5 Go with lens L）
Steps：In pic 5 it marked out which parts of the microscope are involved to each step.
①Install and fix lens L to the bottom of the focusing tube.
②Bend the two goose-neck spot lights, make the field of view enough illuminated.
③Loose the Arm V-locker, locate the whole monitor part to a desire height (distance from the lens to the
specimen should be around 90mm to300mm), then fix the V-locker. In order to adjust object distance
more precisely, adjust the height of the secondary bracket. The shorter the object distance is, the bigger
magnification is.
④Turn the focusing tube to get a clear image. Turn it clockwise to zoom in and the other way to zoom
out.
Lens A：
Working distance：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.

8
（pic 6 Go with Lens A）
Steps：In pic 6 it marked out which parts of the microscope are involved to each step.
①Install and fix lens A to the bottom of the focusing tube.
②Bend the two goose-neck spot lights, make sure the light shines on the coin.
③Loose the Arm V-locker, locate the whole monitor part to a desire height (distance from the lens to the
specimen should be around 12mm to 320mm), then fix the V-locker. In order to adjust object distance
more precisely, adjust the height of the secondary bracket. The shorter the object distance is, the bigger
magnification is.
④Turn 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, get a clear image.
*Steps above can also be applied to observe plants, stones etc.

9
Lens D：
Working distance：4mm-5mm，
Magnification：450-510x（with3 times digital zoom)
Applications: Microscope slides etc.
（Pic 7 Go with lens D）
Steps：In pic 7 it marked out which parts of the microscope are involved to each step.
①Install and fix lens D to the bottom of the focusing tube.
② Place a slide on the slides holder and power on the slides holder. (goose-neck spot lights can not
provide proper illumination in this case, so leave them and use the same interface to power on slides
holder)
③Loose the Arm V-locker, locate the whole monitor part to a desire height (distance from the lens to the
specimen should be around 4mm to 5mm), then fix the V-locker. Since the focus range is very short in
this case, we recommend users to adjust the height of the secondary bracket instead, which is more
precisely. The shorter the object distance is, the bigger magnification is.
④Turn the focusing tube to get a clear image. Turn it clockwise to zoom in and the other way to zoom
out.
*Lens D’s magnification is quite big, which requires a short object distance. Meanwhile, any tiny
movement or shake of specimen would be displayed as huge on the monitor, which requires user to
operate very carefully and patiently.

Trouble shooting
1.The microscope can’t be switched on.
Please check the connection is exactly as pic 4 shows, 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 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 use a piece of 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 the 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.
4. It shows “card error” or “card is full” after inserting memory card to the device.
Please format the card after insert it into the device.（Format steps refer to chapter “Save files to micro
SD card”)
