SAFETY NOTES
1. Open the shipping carton carefully to prevent any accessory, i.e. objectives or eyepieces, from dropping
and being damaged.
2. Do not discard the molded shipping carton; the container should be retained should the microscope ever
require reshipment.
3. Keep the instrument out of direct sunlight, high temperature or humidity, and dusty environments. Ensure
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. All electrical connectors (power cord) should be inserted into an electrical surge suppressor to prevent
damage due to voltage fluctuations.
6.
LAMP REPLACEMENT -- CAUTION
: the glass housing 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.
7.
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.
8. 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.
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 such as cotton swabs or
Q-tips, 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.

microscopes are precision instruments which require periodic preventative maintenance to
maintain proper performance and to compensate for normal wear. An annual schedule of preventative
maintenance by qualified personnel is highly recommended. Your authorized UNITRON
