Caution  

 

1.  Find the “UP” sign and place the Styrofoam container on your table or bench so 

that the arrow is pointing upward. Open the shipping carton carefully to prevent 
any accessory items (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.  For safety when replacing the halogen lamp or fuse, be sure the main switch is off, 

unplug the power cord, and only replace the halogen bulb after the bulb and the 
lamp house has completely cooled.   

 

8.  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.
