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.

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. For functions, see section 3.2.1.5
