Note: Automated Tip/Tilt alignment is an optional accessory that may or
may not have been purchased with your system. If your purchase

System Alignment (with Manual Tip/Tilt).
System alignment is the adjustment of the source and receiver components
relative to the variable angle base of the M-2000 system. It is required when the
system is first delivered, when first mounting the system onto a base or
chamber, or whenever the integrity of the alignment is in question. Figure 4-25
