*Troubleshooting
If the display freezes, locate the “reset ” hole(as Figure 2 shows) on the
back of the monitor. Use a narrow object such as an unfolded paperclip to
depress the button located inside. This resets all settings to their factory
values and restarts the display . It does not erase saved images or video.

(Note: When observing the slides, try to use 3 different
light barriers and adjust the brightness of the built-in LED
light to obtain the desired image effect.)
Uniform light plate: When observing the
microscope slides, it can make the bottom
illumination more uniform and the image more clear.
Black backlight: When you need to observe the
details of small objects, it can make the sensor
increase the image gain and the details clearer.
White backlight: When a white background image
is needed, it can be used.
