IMPORTANT SAFEGUARDS
Read these instructions carefully and retain them for future use.
If this product is passed to a third party, then these instructions
must be included.
When using electrical appliances, basic safety precautions should always
be followed to reduce the risk of fire, electric shock, and/or injury to
persons including the following:
WARNING It is prohibited to disassemble the machine.
WARNING Risk of serious injury! Dyes are harmful by inhalation,
harmful in contact with skin, harmful if swallowed.
Methylene Blue Dye: Avoid eye and skin contact. Causes serious eye
irritation. Do not swallow. Do not inhale.
First aid in case of eye contact: Immediately flush eyes with
excess water for 15 minutes, lifting lower and upper eyelids
occasionally. Remove contact lenses if wearing any. Get
medical attention if irritation develops.

without medical advice. Consult a physician if necessary.
NOTICE Methylene Blue dye has been classified by the International
Agency for Research on Cancer (IARC) as Group 3: Not classifiable as
carcinogenic to humans.
NOTICE Use the product within the correct ambient conditions to
avoid mildewing and damage.
• Keep the work area clean, clear and away from any food storage.
Prepare the slides in a well-lit area and close to a water supply. Use a
solid table with a heat-resistant top.
• Do not allow dyes to come into contact with any part of the body
particularly mouth and eyes.
• Do not eat, drink or smoke in the work area.
• Clean all the accessories and the work area after each use.
Wash hands thoroughly after handling and carrying out
experiments.

EN
• A separate tin or bucket should be used for the disposal of specimen
samples and dyes. Any wasted solution should be poured directly
down a drain, but never into a sink basin.
• Dispose of used specimen samples a household trash immediately
after use.
• Do not discard any equipment into the fire to avoid violent
combustion or explosion.
• If the product has to be moved, carry with one hand holding the

damaged housing, or parts. In the event of such damage, the set
should not be used until it is properly repaired.
• Store the set in its original packaging out of reach of children and
animals.
Grounding Instructions
This product must be grounded while in use to protect the operator
from electrical shock. The appliance is equipped with a 3-conductor
cord and a 3-prong grounding-type plug to fit the proper grounding-type
receptacle. The appliance has a plug that looks like sketch A in the figure
below. An adapter, sketch B, should be used for connecting sketch-A
plugs to two-prong receptacles. The grounding tab which extends
from the adapter must be connected to a permanent ground such as a
properly grounded outlet box as shown in sketch C using a metal screw.

To use the mirror instead of the transmitted light lamp (I):
• Attach the mirror (AD) onto the mirror stand (AE)
• Unscrew the diffuser of the transmitted light lamp (I) from the base.
• Screw the mirror stand (AE) onto the base.
NOTICE Using the mirror does not require electrical connection.
Operation
Switching on/off
• Connect the power cord (AF) to a power outlet and the other end to
the power socket (P).
NOTICE To prevent the bulb in the lamp (I) from burning, turn the
brightness adjustment wheel (Q) setting to the lowest before turning on
or off.
• Flip the power switch (R) to “I” to turn on the lamp (I).
• After use, flip the power switch (R) to “O” to turn off.
Calculating magnification power
Total magnification power is calculated by multiplying the magnification
power of the eyepiece and the objective lens.

• Remove the eyepiece covers (A) and place in eyepieces (Z/AA).
• Turn the coarse focus knob (L) to adjust the height of the stage (G) to
the lowest position.
• Rotate the nose piece (E) to the lowest magnification power setting.
NOTICE Start with the lowest magnification power every time a
new slide is placed on the stage (G). Most observations are made at low
magnification power.
• Clip a slide (not included) onto the stage (G), securing with the stage
clip (F).
• Without looking into the eyepiece (Z/AA), turn the coarse focus knob
(L) until the objective lens is close to the slide. The objective lens
should not touch the slide.
• Adjust the position of the slide using the X and Y translation controls
(N, O).
NOTICE If the lamp (I) is used, adjust the brightness of the lamp (I)
using the brightness adjustment wheel (Q).

NOTICE To use the color filter (AB), slide open the base of the
condenser (H) and place the color filter (AB) inside.
• Look into the left eyepiece (Z/AA), rotate the fine focus knob (M) and
the left diopter adjustment (B) slowly until the image is clear. Adjust
the position of the slide if needed.
CAUTION Risk of damage! Never force the adjustment knobs
(M), (L) and, (U) to turn further once the knob is already restrained from
turning. It may cause friction and scratch the lenses.
• The condenser (H) is adjusted to focus the light unto the specimen.
Tinker around with the condenser (H)’s vertical knob (U), diaphragm
(T), and the locking screw (AG) to achieve the sharpest image.
NOTICE The condenser diaphragm (T) gathers the available light
and concentrates it to illuminate over the specimen with uniform intensity.
• Look into the right eyepiece (Z/AA), rotate the right diopter
adjustment (B) until the image is clear.

• Look into both eyepieces (Z/AA), adjust the distance of the
interpupillary distance adjustment (C) until the two images merge
intoone.
NOTICE After focusing, there is an option to push up the locking set
(S) to keep the adjustment knobs (L, M) in place.
• Rotate the nose piece (E) to the next objective lens, increasing in
magnification power. Re-adjust the focus using the fine focus knob
(M) if needed.
• After using the microscope, remove the slide from the stage (G), take
off the eyepieces (Z/AA) and place the eyepiece covers (A) back on.
• Turn to minimum the adjustment wheel (Q).
• Switch off (R) and disconnect the power cord (AF) from the power
outlet.
• Clean the work area and dispose of the used specimens.
Cleaning and Maintenance
CAUTION Risk of electric shock! To prevent electric shock,
unplug the product before cleaning.
CAUTION Risk of electric shock! During cleaning do not immerse
the product in water or other liquids. Never hold the product under
running water.
Cleaning
• To clean the lenses (V, W, X, Y, Z, AA), only use lens cleaning tissues.
Do not use cloth, paper or hands. Rotate the objective lenses (V, W,
X, Y) counter-clockwise to remove them from the nose piece (E).
