MASTER TUNING

The piano is tuned to A = 440Hz when the power is
turned on. However, if desired, the tuning may be
adjusted in small increments from -64 to +63 cents
(one semitone).

TO CHANGE MASTER TUNING

Press the [METRONOME] and [TEMPO] buttons
together to enter edit mode.
Press the A#-1 key to select the master tuning
function.
Please note: the keyboard will now play middle
C, piano 1 voice (key C3) on every note across the
keyboard. Pressing any key from C3 down to A#1
will play note C3 but change the tuning setting
proportionately to tune down by a whole semitone,
as desired.
Pressing any key from C3 and up will play the C3
note but change the tuning setting proportionately
to tune up by a whole semitone, as desired.
The piano display will show the selected values.
