AI igning the position ing dots on con -

denser mount and condenser, insert the

condenser into the mount from below.To remove the condenser, remove the

auxiliary lens first.

aliqned.

Prior to mount ing the stage, rack down

the condenser mount all the way. To re-

move the stage, remove the condenser

first .
