i. Caution

1. Open the carton carefully with a knife or paper cutter. Find the “UP” sign and place

the Styrofoam container on the side that makes the arrow upward. If the “UP”sign

is missing, please open the Styrofoam container gently to prevent any accessory,

i.e. objectives or eyepieces, from dropping and being damaged.

2. Do not discard the molded Styrofoam container. The container should be retained

should the microscope ever requires reshipment.

3. Keep the instrument out of direct sunlight, high temperature or humidity, and dusty

environments. Ensure that the microscope is located on a smooth, level and firm

surface.

4. If any specimen solutions or other liquids splash onto the stage, objective or any

other component, disconnect the power cord immediately and wipe up the spillage.

Otherwise, the instrument may be damaged.

5. Important: the lamp, lamp housing and adjacent parts will become very hot. Do

not touch these parts until they have completely cooled. Never attempt to handle a

hot halogen bulb.

6. All electrical connectors (power cord) should be inserted into an electrical surge

suppressor to prevent damage due to voltage fluctuations.

7. Confirm that the input voltage indicated on your microscope corresponds to your

line voltage. The use of a different input voltage other than that as indicated will

cause severe damage to the microscope.

ii. Care and Maintenance

1. Do not attempt to disassemble any component including eyepieces, objectives or

focusing assembly.

2. Keep the instrument clean; remove dirt and debris regularly. Accumulated dirt on

metal surfaces should be cleaned with a damp cloth. More persistent dirt should be

removed using a mild soap solution. Do not use organic solvents for cleansing.

3. The outer surface of the optics should be inspected and cleaned periodically using

an air stream from an air bulb. If dirt remains on the optical surface, use a soft cloth

or cotton swab dampened with a lens cleaning solution (available at camera

stores). All optical lenses should be swabbed using a circular motion. A small

amount of absorbent cotton wound on the end of a tapered stick makes a useful

tool for cleaning recessed optical surfaces. Avoid using an excessive amount of

solvents as this may cause problems with optical coatings or cemented optics or

the flowing solvent may pick up grease making cleaning more difficult. Oil

immersion objectives should be cleaned immediately after use by removing the oil

with lens tissue or a clean, soft cloth.

4. Observe the specimen with the 4X, 10X and 40X objectives in order, then observe

the specimen with the 100X objective. Apply the immersion oil on the slide cover

with the 100X objective. Do not let the immersion oil to contact with the dry

objectives lens (especially the 40X). Clean the dry objective lens using the lens

cleaning paper if the immersion oil is on the dry objectives lens. Clean the 100X

objective lens first using the lens cleaning paper after observing the specimen with

the 100X objective, then clean the specimen. More persistent dirt should be

removed using a little bit alcohol. Do not use organic solvents for cleansing.

5. Store the instrument in a cool, dry environment. Cover the microscope with the

dust cover when not in use.

2Installation

2.1 Installation of the binocular viewing head

1) Loosen the head thumb lock screw on the top of the microscope body and remove

the plastic cover on the top.

2) Remove the cap on the dovetail of the binocular viewing head.

3) Seat the dovetail completely of the viewing head into the socket on the top of the

microscope body and tighten the head thumb lock screw.

Caution:

Do not release the viewing head from your hand grip until you are sure the viewing

head is installed securely.

2.2 Installation of the eyepieces

1) Remove the protective caps from the eyepiece tubes.

2) Insert the eyepieces into the eyepiece tubes.

2.3 Installation of the objectives

1) Adjust the coarse focus knob until the mechanical stage is at its lowest position.

2) Turn the caps counter-clockwise to remove them from the nosepiece.

3) Take the objectives out from the plastic cases and turn each one clock-wise into the

holes on the nosepiece. Install the 4X objective into the nosepiece first. Then in a

counter-clockwise direction, rotate the nosepiece and install each succeeding higher

magnification objective as shown in Fig. 1.

Note:

Inspect the objectives frequently for dirt or oil; clean if necessary.

Use the 10X objective to initially focus the image of your specimen.

When changing the objective magnification, rotate the objective nosepiece until

you hear a “click” sound or have a clear "in position" feeling. This ensures the

objective is centered in the optical light path.

2.4 Installation of the glass filter

1) Swing out the color filter holder under the condenser.

2) Place the filter into the holder as shown in Fig. 2, swing the holder in.

3Operation

3.1 Adjusting illumination

1) Plug the power cord into the power socket on the microscope and connect it to the

power outlet.

2) Turn on the power switch.

3) Rotate the brightness intensity dial to increase or decrease the brightness.

Caution:

A diffusion filter is attached beneath the condenser to get uniform light and protect

your eyes from strong light when a low power objective applied. The diffusion filter

can be swung out to make the view field brighter when observing with a high power

objective, such as 100X objective.

3.2 Placing specimen

1) Place the slide on the mechanical stage.

2) Use the slide holder to gently secure the slide.

3) Turn the X and Y stage moving knobs to position the specimen in the center of

viewing field.

Caution:

Be sure not to allow an objective to touch a specimen slide when changing objectives.

3.3 Adjusting interpupillary distance

While observing with both eyes, hold the left and right eyepiece tubes then slide the

tubes in and out. The interpupillary distance is correct when the left and right fields of

view converge completely into one image.

3.4 Adjusting eyepiece diopter

1) Rotate the 10X objective into position.

2) Rotate the diopter rings on the eyepiece tubes

until its numerical value is the same as your

interpupillary distance, for example, 70 in the

figure (See Fig. 7).

3) Close your left eye and bring the specimen

into focus following the focusing procedures in

3.5.

4) Close your right eye and bring the same

specimen into clear sharp focus by adjusting

the diopter ring on left eyepiece tube only. Do

not use focus knobs at this step.

5) Since both sides are adjustable, you may also

do the above in the opposite way, in other

words, left eye first and right eye second.

3.5 Focusing

1) With the 10X objective in position, raise the mechanical stage using the coarse

focus knob until the specimen is close to the objective.

2) Turn the coarse focus knob until the specimen is in focus.

Fig.7

3) Use the fine focus knob to obtain a sharp image.

4) To get a good focused image, you may need to combine the focus knob adjustment

and interpupillary distance adjustment, along with eyepiece diopter adjustment

stated in 3.3and 3.4.

5) You may now switch to another magnification objective.

Tips:

To prevent your specimen slide from making contact

with an objective, raise the stage to its highest position

without contacting the 100X objective, then tighten the

focus stop lever (Fig. 8). Give the stage a tiny extra

moving space to ensure the objective can be focused

every time.

3.6 Applying the immersion oil

1) Rotate the objective nosepiece to seat the observing position between the 40X and

100X objectives as shown in Fig. 9 (a).

2) Place a drop of immersion oil on the slide cover as shown in Fig. 9 (b).

3) Rotate the objective nosepiece to seat the 100X objective to the observing position

until you hear a “click” sound.

4) After observing the specimen, use the lens cleaning paper to clean the 100X

objective lens gently and the specimen in time.

5) If it is hard to clean, you need a little bit alcohol to clean the 100X objective lens and

the specimen.

Caution (important):

When you use the 100X objective to observe the specimen, you have to finish

observing the specimen with the 4X, 10X, 40X objectives.

When you use the 100X objective to observe the specimen, you have to apply the

immersion oil on the top of the slide cover.

When you apply the immersion oil with the 100X objective, do not let the

immersion oil to contact with the dry objective lenses (especially the 40X). If the

immersion oil is on the dry objectives lens, please use the lens cleaning paper to

clean the objectives lens in time. The oil will damage the dry objective lenses.

After observing the specimen with the 100X objective, clean the 100X objective

lens first.
