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 such as a Q-tip or cotton swab, 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 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
