How to refocus
The entire stage can be lowered by setting a finger
on the refocusing lever or top surface of the stage
and pushing down. When the finger is released, the
stage slowly returns to its original position.
If the stage is lowered to the lowest position, it will
be locked in that position.
Push down once again to disengage the lock,
allowing the stage to slowly return to the original
position.
This function is useful when replacing specimens.
Be sure to lower the stage slowly.
