meter 7Hz).

To connect the Amp unit and the DSP unit, use Jig GGD1153 and GGD1245.

Caution:

1) Before starting measurement, be sure to perform the initial check for the ASL adjustment jig. (The sound pressure

level should be 100dBSPL at the sound emission section.)

2) Note that it may take 20 seconds or more to obtain waveforms, in some cases. Do not switch off the jig soon after

starting measurement.

Conditions:

1) This adjustment is sensitive to external shocks or wind. During adjustment, keep away the product and jig from

them.
