<Note>
- Initial inspection for ASL adjuster must be done before measurement.
(Sound pressure transfer part must be 100dBSPL.)
- Never turn the SW Off even when waiting for over 20 seconds before appearing the waveform.
<Environmental Conditions>
This adjustment should not be done because it tends to be affected by vibrations and winds.
