-The G level should be upped to the sound
skip level from the less level slowly at the
frequency.
-Ignore the sound skip at the near of
resonance frequency(about 100Hz).
-In playing YEDS-10 Tr #5, shall perform with
vibration
-No sound skipping.
-No sound skipping in the specified range.
-The sound skipping does not include any
interpolating noise.
-No sound skipping at the ABEX 731RA Tr
No8
-The sound skipping does not include any
interpolating noise.
-Except from specified item due to the
reliability limits of TEST DISC in the HTO
TEST.
