Table 4 - Checklist B (General)
CHECKLIST B (Paragon-III)
General Check out (part1 of 2)
Paragon-III 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
performance degradation is noticed combined with out-of-tolerance items.

BDLC-III beeps once, all LEDs come ON for about four seconds, the green LEDs then
flash in a “ripple” pattern for close to two seconds. All LEDs go OFF except the CK that
should flash 6 to 8 times per second.
