Installing a new Laser Optics Housing Unit

install the new unit, do not remove the bracket until near the end of the installation
procedure (the correct time is stated in the manual).
This bracket protects a capacitor on the unit. If the bracket is removed too early,
you could break the capacitor on the corner of the main frame when you install the
new unit.
