CHECKLIST B (
Paragon4
)
General Check out (part1 of 2)
Paragon4 units are set and characterized at the factory to optimize performances.
It is not recommended to try readjusting units unless it is really required.
Misadjusting a unit may result in significant performance losses.
The proposed adjustments in the "IF NOT?" column below, should be tried ONLY if system data per-
formance degradation is noticed combined with out-of-tolerance items.
