the metronome while either of the two above operations
is already in progress causes the metronome to sound
in time with the Auto Accompaniment played by the
keyboard. At this time, the tempo of the metronome beat
changes to that of the default tempo for the Auto
Accompaniment being played.

Using a Microphone for Sing Along
You can select any of the 50 Song Bank/Sing Along Group
tunes and sing along with its accompaniment.
Using the microphone jack
Connecting a commercially available microphone* to the MIC
jack makes it possible to sing along with the keyboard’s built-
in tunes or with output from a MIDI device. When connecting
a microphone, be sure to first adjust the MIC VOLUME to a
relatively low setting, and then adjust to the level you want
after connecting.
*If a microphone was included with your keyboard, use that
microphone. If your keyboard did not come with a
microphone, use a commercially available microphone that
satisfies the stipulated specifications.
1Set the MIC VOLUME knob setting so it is on the
“MIN” side.
2Turn on the microphone’s ON/OFF switch.
3Use the MIC VOLUME knob to adjust microphone
volume to the level you want.

off the microphone and to disconnect the microphone
from the keyboard whenever you are not using it.Required Microphone Specifications
•Microphone Type : Metal shielded (microphone
body)
•Microphone and Cord
Connector : Cannon type (3-prong)
•Keyboard Jack Connector : Standard plug (monaural)
IMPORTANT!
•Connection to the MIDI terminal of an external device
can cause static in the microphone signal. Use of a
Cannon type microphone with a metal-shielded body
helps to prevent static.
•Be sure to disconnect the microphone from the keyboard
whenever you are not using it.
Howling (Feedback Noise)
Any of the following conditions can cause howling (feedback
noise).
•Covering the head of the microphone with your hand
•Positioning the microphone too near to a speaker
Should howling occur, try grasping the microphone further
away from the head, and move away from any nearby
speaker.
Static Noise
Fluorescent lighting can cause static noise in the microphone
signal. When this happens, move away from the lighting you
suspect may be causing the static.

accordance with the chords you finger. The bass and chord
parts are played using sounds and tones that are
automatically selected to select the rhythm you are using.
All of this means that you get full, realistic accompaniments
for the melody notes you play with your right hand, creating
the mood of an one-person ensemble.

							E-37
NOTE
•Except for the chords specified in note*1 above, inverted
fingerings (i.e. playing E-G-C or G-C-E instead of C-E-
G) will produce the same chords as the standard
fingering.
•Except for the exception specified in note*
2 above, all
of the keys that make up a chord must be pressed.
Failure to press even a single key will not play the desired
FINGERED chord.
FULL RANGE CHORD
This accompaniment method provides a total of 38 different
chord types: the 15 chord types available with FINGERED
plus 23 additional types. The keyboard interprets any input
of three or more keys that matches a FULL RANGE CHORD
pattern to be a chord. Any other input (that is not a FULL
RANGE CHORD pattern) is interpreted as melody play.
Because of this, there is no need for a separate accompaniment
keyboard, so the entire keyboard, from end to end, can be
used for both melody and chords.
