Note that the supported output range is 200 to 4000 Hz. If an error occurs, tap [OK] and then perform the procedure from the beginning. (8) To terminate sound output, press the EA-200 [START/STOP] key.
9-15 E-CON Graph Window Operations (4) After the settings are configured is the way you want, tap [OK]. • This displays a dialog box like the one shown to the right. (5) Tap [OK]. • This outputs the sampled sound from the EA-200’s speaker. (6) To terminate sound output, press the EA-200 [START/STOP] key. (7) Tap [OK]. This returns to the Speaker Output window of step (1). • To return to the E-CON Graph window, tap the [Stop] button.
9-16 E-CON Graph Window Operations Tip • The time value is always stored as seconds. • The storage capacity of the above data storage operation is limited. If an error occurs, use [File] [Save List] to store the data as a list.
