SAFETY NOTES
1. Open the shipping carton carefully to prevent any accessory, i.e. objectives or eyepieces, from
dropping and being damaged.
2. Keep the instrument out of direct sunlight, high temperature or humidity, and dusty environments.
3. 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.
4. LAMP REPLACEMENT -- CAUTION: the glass envelope of the lamp may be extremely
hot. DO NOT attempt to change the lamp before it is completely cooled or without
wearing adequate skin protection.
5. All electrical connectors (power cord) should be inserted into an electrical surge protector to prevent
damage due to voltage fluctuations.
6. FUSE REPLACEMENT -- For safety when replacing the fuse (ONLY replace with the
same size, type and rating of original fuse), be sure the main switch is in the off position,
disconnect the power cord from outlet, and replace the fuse. Reconnect the power cord
and turn unit on.
7. Confirm that the input voltage indicated on your microscope corresponds to your line voltage. The
use of a different input voltage other than indicated will cause severe damage to the microscope.
NOTE: Always plug the stereomicroscope power cord into a suitable grounded electrical outlet. A
grounded 3-wire cord is provided.
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, lint free 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.
4. Store the instrument in a cool, dry environment. Cover the microscope with the dust cover when not
in use.
5. UNITRON® microscopes are precision instruments which require periodic servicing to maintain
proper performance and to compensate for normal wear. A regular schedule of preventative
maintenance by qualified personnel is highly recommended. Your authorized UNITRON® distributor
can arrange for this service.

ASSEMBLY
The following photos show how to assemble the various modules in the order of assembly.
When assembling the microscope, make sure that all parts are free of dust and dirt, and avoid scratching
any parts or touching glass surfaces.
Installing the Focus Arm
For microscopes ordered with the Plain Focusing or LED stands the focus mount should be positioned at
the higher position on the track. There are two positions on the dovetail track in which the focus mount
can be installed. The positions are spaced 55mm apart. Should you need to lower the position of the
focus mount for the future please follow the following steps:
1. Remove the viewing head, optical body and objective from the focus mount by loosening
the locking screw on the focus mount.
2. Using the allen key that was supplied with your stand loosen the allen screw at the rear of
the focus mount that connects the focus mount to the dovetail.
3. Align the screw hole opening on to the lower screw opening on the dovetail.
4. Align the two pins on the focus arm into the grooves on the dovetail slider.
5. Tighten the allen screw into place.
6. Reinsert the viewing head, optical body and objective into the focus mount and lock the
assembly back into the focus mount by tightening the locking screw.

Adjusting Interpupillary Distance (Fig. 6)
Different users have different interpupillary
distances (this distance is between the centers
of the pupils of each eye). When the operator of
the microscope changes, it will be necessary to
adjust the interpupillary distance.
While looking through the eyepieces, hold the
left and right eyetubes of the viewing head and
adjust the eyetubes by opening or closing them
until the left and right fields of view coincide
completely and you are able to see a complete
circle.
Adjusting Diopter Ring/Focusing (Fig. 7)
Set the diopter rings ② of both eyepieces to “0”
position. (Do this when users change, because
different users will have different diopter
settings.)

magnification, and turn the focusing knob ④ to
focus the specimen.
Rotate the zoom knob ③ to the lowest
magnification, looking only into the left eyepiece,
adjust the diopter ring on left eyepiece to focus
the specimen. Then repeat this procedure for
the right eyepiece.
NOTE: The working distance (the distance
between the microscope objective to the top of
the specimen) of the microscope is 78mm (with
the 1x Plan objective).
