TUNING THE KEYBOARD

Although your keyboard never goes out
of tune, it does let you adjust its pitch to
match other instruments or musical re-
cordings.
Note: You cannot tune the keyboard
while a prerecorded tune is displayed or
playing.
Follow these steps to tune the keyboard.
1. Repeatedly press
until the display shows
TUNE/MIDI
and the current pitch setting.
Tune
Note: The number on the display is
the number of "cents" to which the
keyboard is currently tuned, com-
pared to its default pitch. A cent is
the measurement that represents
the acoustical interval between two
tones. 1200 cents equal 1 octave.
You can tune the keyboard to within
50 cents (101 levels) of its default
pitch.
2. Within 5 seconds, repeatedly press
or to lower or raise the key-
– +
board's pitch. Each time you press
the key, the number on the display
decreases or increases by 1 (cent).

Notes:
• You can use the number keypad to
raise the pitch by entering the cent
change value.
• The keyboard automatically resets
the tuning pitch to the default value
of 00 (cents) each time you turn off
the keyboard or play the pre-
recorded tunes.

make music, you can connect an option-

your local RadioShack store). A sustain
pedal lets you sustain the keyboard's
sound.
To connect a sustain pedal to your Con-
certmate 980, insert the plug on the ped-
al's cord into
