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. 

2.7  Installing the mirror (optional, your model may not have one) 

1)  Unplug the power cord. 
2)  Screw off the light cover on the base. 
3)  Screw the black disc onto the base and then insert the mirror 

into the hole at the center of the black disc. You may try to get 
reflected ambient light on either side of the mirror with different 
angles for best result. 

Note: 

The mirror is only used when there is a power failure or you are in the field and no 

power is available.
