Caution 

1.  Open the carton carefully with a knife or paper cutter. Find the “UP” sign and place 

the Styrofoam container on the side that makes the arrow upward. If the “UP” sign 
is missing, please open the Styrofoam container gently 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.  For safety when replacing the LED light and the fuse, be sure the main switch is 

off, unplug the power cord, and replace the LED light and the fuse 

7.  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.   

8. 

Note:

 please read the instruction of the operation of camera in manual 

3.9

 below 

and the CD in the package before you start to use it.
