# The focus adjustment knob is installed on the right side of the micro-
scope when it left the factory.

ence with hand during manipulation of the focus adjustment knob or X/
Y-axis knobs.
Usually attach the knob on the opposite side to the stage feed knobs.
1. Loosen the clamping screw @ and remove the focus adjustment knob
².
2. Remove the seal from the focus adjustment knob screw hole on the
other side and attach the knob by reversing the removal procedure.
3. Attach a provided seal on the screw hole | of the focus adjustment dial
³, from which the focus adjustment knob has been removed.
}The focus adjustment dial ³ can be operated with your fingertip or finger
surface at the same time as manipulating the X/Y-axis knobs.
