2.13 Electromagnetic immunity
When properly installed in a representative host system, the drive operates without errors or degradation in
performance when subjected to the rradio frequency (RF) environments defined in the following table:
A - 1) No upset or degradation in performance beyond manufacturer’s specified limits.
2) No data loss.
B - 1) Unit self recovers without user intervention.
2) No data loss.
C - 1) Upset OK provided that unit will function after user intervention.
