Connect the included miniature speaker to the ‘SPEAKER’ connector SK7 using the supplied wire. If you decide
to use a different speaker, get one with an impedance between 4 and 8 ohms, and a power rating of 0.25W to 2W.
Higher power ratings will result in poor performance.

the ‘RECORD’-button to end the recording. If LD1 turns off during recording, the memory is full and recording is
stopped. Max. recording time is 20 seconds.
