TUNING THE KEYBOARD

Although your Concertmate 970 never goes out of tune, it does let you adjust its pitch to match other instruments or musical recordings.

Note: You cannot tune the keyboard while the juke box mode is turned on.

1.Press and hold SOUND, then press and release JUKE BOX. The display shows the current pitch setting.

0	1	2	3	4	SOUND
					MELODY
					ON/OFF
5	6	7	8	9	RHYTHM

Note: The number on the display is the number of “cents” to which the keyboard is currently tuned, compared to its default pitch. A cent is the measurement that rep- resents the acoustical interval between two tones. 1200 cents equal 1 octave.

2.Within 5 seconds, repeatedly press TRANSPOSE/TUNE s or t to raise or lower the keyboard's pitch. Each time you press the key, the number on the display increases or decreases by 1 (cent).
