SAFETY
Do not disassemble any parts of the microscope, except where noted in
the instruction manual.
In case of a problem with the microscope, contact a professional
repairman or the manufacturing factory.
The microscope should be kept at temperatures between 0C –40C / 32F
–104F, with a maximum humidity of 85%.
Do not place the instrument in direct sunlight or under direct indoor light.
This environment can influence the quality of the specimen imaging.
Do not place the instrument in a dusty environment. When not in use,
cover the microscope with a dust cover.
Keep the instrument on a level and sturdy surface.
Carry the microscope with two hands, one hand underneath the base unit
and the other grasping the “neck”of the microscope.
PARTS LIST

One eyepiece: Widefield 10x
Three (3) objectives (4x, 10x, 40x)
One AC/DC adapter power block (OM136CL only)
One plastic dust cover
One manual
FEATURES
The OM136C and the OM136CL are full featured monocular microscopes
designed for research, instruction and experiments in universities and technical
secondary schools. This microscope has a magnification range of 40x to 400x.

ASSEMBLY
1. Remove microscope from Styrofoam packing and place it on a stable
worktable. Remove all plastic bags and paper covering (these can be
discarded).
2. Connect cord to power supply and your microscope is ready for use.
OPERATION
1. Make sure the 4x objective lens is in position for use. This will make it easier to
put your slide in place as well as to position the item you wish to look at. (You start
at low magnification and work up.) Put a slide on the stage and clamp it carefully
with the moveable spring clip.
2. Connect the power and turn on the switch.
3. Always begin with the 4x objective. Turn the coarse focus knob until a clear
image is obtained, then use the fine focus knob to enhance the observation of
the specimen to its clearest image. When the desired view is obtained under the
lowest power (4x), rotate the nosepiece to the next magnification level (10x).
The nosepiece should “click” into position. Adjust the focusing knobs as needed
to once again find a clear view of the specimen.
4. Turn the coarse adjustment (large) knob, observing the image of the specimen
through the eyepiece. Use the fine adjustment (small) knob for more clarity.
5. The iris diaphragm below the stage can be opened (slide lever forward) or
closed (slide lever back to left) to control the amount of light directed through the
condenser. The condenser assembly under the stage can be shifted up or down
by means of the control knob (left hand side under stage) to effectively move the
light beam closer to (up) or away from (down) the specimen under observation.
Try experimenting with various settings to get the most effective view of your
specimen.
6. It is important to remember when adjusting the focus that the objective should
never touch the specimen. When increasing to OPTIONAL 100x objective, the
objective will appear to be very close to the slide. Because the 100x is an oil
immersion objective, a drop of cedar-wood oil or other immersion oil should be
applied in the gap between the objective and the specimen. (Note: All slides
should be prepared with cover slips over the specimen for observation under the
100x objective.) The 100x oil immersion objective should be wiped off with a
piece of soft clean cloth or lens tissue to remove the immersion oil immediately
after using. It is strongly recommended if requesting the 100x objective to also
purchase the mechanical stage option.

MAINTENANCE
1. The microscope should be kept out of direct sunlight in a cool, dry place, free
from dust, fumes and moisture. It should be stored in a case or covered with a
hood to protect it from dust.
2. The microscope has been carefully tested and inspected. Since all lenses
have been carefully aligned, they should not be disassembled. If any dust has
settled on the lenses, blow it off with an air blower or wipe off with a clean soft
camel hairbrush. In cleaning mechanical parts and applying non-corrosive
lubricant, take special care not to touch the optical elements, especially the
objective lenses.
3. When disassembling the microscope for storage, always put the covers on the
nosepiece opening to prevent dust settling inside the lenses. Also keep the neck
of the head covered.
4. The 100x oil immersion objective should be wiped off with a soft, clean cloth or
lens paper immediately after using.

Power and Illumination for the OM136L
The input voltage is.110v~240v AC 50/60hz. into the AC/DC
adapter power block.
The output voltage is 4.5v @1000ma out of the AC/DC adapter
power block.
Do not overcharge the internal batteries. Remove AC power
when batteries are charged (approximately 2 hours).
If the internal batteries need replacement, slide the battery
cover forward (in direction of arrow) and lift off. Three NiMH
“AA”s are used. Replace when microscope fails to hold a
charge.
The LEDs do not require maintenance.
