Calibrating the tuner

Calibration specifies the reference pitch for tuning (expressed
as the frequency of the middle 'A' note on a piano). You can
adjust this in a range of 438 Hz–445 Hz.
NOTE: The calibration setting you specify here will be dis‐
carded when you turn off the power. When you turn
the power on again, it will automatically be set to 440
Hz.
1. Activate the tuner as described in step 1 of "Tuning pro‐
cedure" (p. 29).
2. While holding down the EXIT/TUNE switch, use the
BANK UP/DOWN pedals to adjust the reference pitch.
The bank/value display will indicate "38"–"45" (438 Hz–
445 Hz). Specify the desired reference pitch.

tion setting.
