Tempo (BPM) isn't measured properly. Why not?

When the audio input level is too high or too low, the BPM value may not be measured. As a guide, adjust the [TRIM] knob so the channel level indicator lights up with the peak level between [0] - [9].

Depending on the track, the BPM value may not be measured correctly. In this case, use the [TAP] button to manually enter the BPM value.
