e) Snap in Power Switch
Snap in the Power Switch to the rectangular hole indicated below. For correct mounting ensure
that the “O” symbol on the switch is oriented as indicated in the figure.
f) Inspect the Completed UI Panel Sub-Assembly
After completing the sub-assembly inspect it to ensure that everything is correctly placed.
Check that:
• All knobs are uniformly seated and appear straight. If a knob is visibly skewed,
check for proper insertion and correct the problem immediately.
• Knobs turn smoothly and do not scrape the cover.
• Check that all knobs potentiometer knobs can turn to
exactly
the 12:00 position
• Pull on each knob until it starts to slide off the stem, then reposition it to its proper
height. This will help identify defective components. The knob must have the
ability to be removed without unseating the stem of its encoder or potentiometer.
• Check that the encoders have negligible wiggle (for missing or incorrect insertion
of the encoder shoulder washers).
• Check that all keycap assemblies have been mounted correctly in the up orientation.
• Test the buttons to ensure that they all have a uniform feel and are not pinched
under the cover. All buttons should depress and pop up freely.
• Re-examine the front panel for cosmetic defects. Look for any marks, scratches or
blemishes. Check for smudges or other defects in the silk-screening.
If the assembly passes the above tests, move on to the next step. Correct any problems
immediately. If you have any quality questions, consult your supervisor.
