How to use: Regarding the names of the parts please refer
to Part II.
1, environmental requirement when in use:
Dry and dust-free. Room temperature should be between –5----+40 C
2, Illuminator control: Plug in the power cord and use the switch.
3, One pair of rubber eye guards is contained inside the packing. They
are used to prevent the extra light from entering the eyepieces, to
improve visibility.
Focusing, diopter, inter-pupillary adjustments:
Place a specimen onto the stage. Loose the body locking thumb
screw and hold the microscope head and move the body up and down
to fix it at the estimated working distance. Rotate the zooming knob
while looking through the right eyepiece until you see the image.
Using the focusing handles to get the sharpest image of the specimen.
Then look through the left eyepiece with your left eyes and turn the
diopter adjustment ring until you get an image as sharp as the right
one. Then grasp the right and left prism housing and move them
closer or father apart in order to match your pupils’ distance.
Adjustment is proper when the field of view becomes comfortable and
presents a full single field.
Lamp and fuse replacement:
Disconnect electric power supply before replacement! Make sure the
bulb to be replaced is not hot.
1, replacement of incident lamp: Take off the incident lamp tube
assembly and you will be able to replace the bulb.
2, Replacement of fuse: Unscrew the fuse holder at the back part of
the base and change the fuse .

damaged by dropping and hitting.
2, Do not keep microscope under sun. It should be kept in a dry and
clean environment and avoid heat and strong tremor.
3, To obtain clear image, do not touch lenses with your finger.
4, All lens surface should be kept clean. If the lens get dusty blow off
the dust with a rubber syringe. If necessary clean the lenses with a lint
free cloth dipped in aether.
5, Do not use any organic material to clean the microscope surface,
especially the plastic surface. It should be cleaned by neutral
detergent.
6, Because the assembly of all parts has been done by skilled optical
craftsmen at the factory, you should never attempt disassembly.
7, Apply a little bit grease regularly to the mechanical parts.
8, When not in use always cover the microscope with the dust cover
and place it in a cool and dry place.
