to “Repeat” and recording time to “15 s”.
3. Press the [REC] key to enable trigger standby.
4. Record voice memo as necessary.

It is also possible to select “SLM” for the “Sens” item

the calibration signal. However, for optimum mea-
surement accuracy, recording the calibration signal
of the sound level meter is preferable.
