2.8.5 Optical Alignment Tool
Product code: T55875.01
The optical alignment tool is used to align the MetroHopper for optimum
efficiency.
The optical alignment tool is fitted on the MetroHopper mounting assembly
before the MetroHopper is fitted. Upon switching on, a red dot is visible through
the eyepiece and this can be adjusted for brightness. A coarse then a fine
alignment is carried using the red dot.
The red dot is aimed towards the centre of the far-end radio and the mounting
assembly is aligned accordingly. During the course of alignment, appropriate
screws are tightened to lock the mounting assembly in the aligned position.
When satisfied that alignment is complete, the optical alignment tool is switched
off and removed from the MetroHopper mounting assembly. The MetroHopper
can then be fitted to the mounting assembly.
