.as~ required by Technical Specifications, when it was identified j-Lthat output voltage was outside the acceptance criteria of a i
surveillance requirement. _The Notice also states, "Your response may, reference or include previously docketed correspondence, if
_i the correspondence adequately addresses the required response."

Full compliance was achieved on the discovery date, August 26, 1996, when the affected inverter was verified to f
be operable by measuring.its output voltage with a digital
.multimeter and confirming output voltage was within the 118 to 4
122.vAC band.
