1. Remove the Back Panel
At the back of the Form 1+, remove two black button-head screws on either
side using the 2.5mm hex wrench. Lift the cover and remove two silver
countersunk screws under the cover. Some machines may also have two
silver countersunk screws along the rear edge on the bottom of the Form
1+.
Carefully remove the back panel after all screws have been removed.
Properly label the galvanometer cables so they will not be switched when
plugging them back in. Unplug the connectors to the Y-Galvanometer, the
X-Galvanometer, and the laser.

easily accessible. Gently wipe the mirror from the base of the mirror to the
end of the mirror. Rotate the swab and wipe again.
