Tuning an Instrument (Tuner)

The BR-900CD has a built-in “chromatic tuner function” that allows you to tune your instrument quickly.

Check the following points before you begin.

•That your guitar is connected to the GUITAR/BASS jack.

•That [GUITAR/BASS/MIC2] indicator on the INPUT SELECT button is lit.
