Assembly QC
The manufacturer is responsible for QC during the assembly of the unit, including all
procedures to ensure that the final unit is clean and free of marks, scratches, and
smudges.
Before the cover is screwed on
The following suggested check is intended as a rough guide for inspecting the unit before
securing the cover of the unit:
1)
Check all components for quality such as scratches, marks, deformities in the
metal work, etc. Check the front lens for scratches, smudges, debris, and other
defects which might cause imperfect viewing of the LEDs behind it.
2)
Check all PCB mounting screws. All audio jacks should be secured to the rear
panel with BOTH a washer AND nut.
3)
Check all cabling for correct orientation and placement. Make sure the cabling is
secure and will not rattle when the unit is moved or turned upside down
4)
Check the fit of all mechanical parts for gaps between pieces that
should fit tightly together.
5)
Check sub-panel assembly for proper interaction with the front panel
such as switch mechanical operation and lens fit. Make sure the lens has been
properly glued and does not extend beyond the front panel.
6)
Check the silkscreen on the front and rear of the unit for correctness of color and
content against the latest design. Make sure that all artwork is clear and correctly
aligned.
7)
Quickly plug the unit into an Alesis P3 type power supply to ensure LEDs light
and proper startup screen appears. While the LEDs are on, check to make sure
that the front lens is clear and working as anticipated.
