1. Adjusting the coarse focus knob until the support device of the mechanical stage reaches its low limit
position.
2. Screw the lowest magnification objective into the nosepiece from the left or the right side, then
revolve the nosepiece clockwise and mount other objectives by the sequence of low to high magnifi-
cation.
Installing objective this way will make the change of magnification to be easier during using.
• Clean the objective regularly, for lens is susceptible to dust.
• When operating, use 10× magnification objective to search and focus specimen firstly, then replace
with higher magnification objective if necessary.
• When replacing the objective, slowly turn the nosepiece until you hear "clicked", that means the ob-
jective is in place.
