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.  All electrical connectors (power cord) should be inserted into an electrical surge 

suppressor to prevent damage due to voltage fluctuations.   

6. 

Important:

 the lamp, lamphouse and adjacent parts will become very hot during 

or short after operation. Do not touch these parts until they have completely 
cooled. Never attempt to handle a hot halogen bulb or mercury bulb. 

7.  Make sure there is sufficient room around the microscope base for heat 

elimination. 

8.  For safety when replacing the lamps or fuses, be sure the main switch is off, 

unplug the power cord, and only replace the bulb after the bulb and the 
lamphouse has completely cooled. 

9.  Do not touch the surface of halogen bulbs with bare fingers. If so, clean the 

surface with soft cloth. 

10. 

Important: 

confirm that the input voltage 

(220V version available, contact seller) 

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.
