1 Play a single string on your guitar or bass.
The LCD will show the note name and the calibration. If the pitch is more
than a semitone higher than the note name, a sharp symbol will appear at
the upper right of the note name.
2 The display area will act as a meter to show the pitch.
Tune each string of your guitar or bass so that the indicator above the center
mark is lit‐up.
Calibration (Standard pitch A = 440)
You can use the Value dial to adjust the calibration in the range of A = 438 Hz–
445 Hz. The calibration setting you make will remain until the power is turned
off. Once the power is turned off, calibration will be reset to A = 440 Hz.
