[. . . ] 5 When tuning an acoustic guitar If you're using a separately sold Korg CM-100 contact mic, connect the CM-100's plug to the GA-40's INPUT jack.

The name of the note closest to the note you played will appear in the upper left of the display. Tune your instrument so that the desired note name appears. If you're using the internal mic, position the mic as close as possible to your instrument, and ensure that extraneous background sounds are not picked up by the mic while tuning. While playing a single note, tune your instrument so that the indicator in the center of the tuning guide is lit (if the tuning reference is A=440 Hz). The left indicator of the tuning guide will light if the pitch of your instrument is too low, and the right indicator will light if the pitch is too high. Each step in the meter is approximately 2 Hz. Power supply Be sure to turn the power switch to OFF when the unit is not in use.
