2.5  Installing (or changing) the halogen bulb 

1)  Turn off the power switch and disconnect the power cord.   
2)  Allow some time to cool down the lamp.   
3)  Turn over the microscope on its side; find the bulb compartment at the bottom. 
4)  Open the cover of the bulb compartment by loosening the thumb screw.   
5)  Take out the dead halogen bulb and insert the new halogen bulb.   
6)  Be sure the pins on the bulb are completely inserted into the lamp socket. You may 

also loosen the two screws on the cover to adjust the position of the bulb to get 
centered and even brightness. See 

Fig. 3

.   

7)  Screw the cover on.   

 
 
 
 
 
 
 
 
 
 

Caution:   

Before you turn over the microscope, be sure to take the eyepieces off and be certain 
that the head is securely locked by the thumb screw. 

2.6  Replacing the fuse 

1)  Turn off the power switch and disconnect the power cord.   
2)  Turn over the microscope on its side; find the fuse holder at the bottom of the base. 
3)  Turn the fuse holder counter-clockwise to take it off, replace the fuse, and then turn 

it on clockwise. See
