Memory Contents
Even when the keyboard is turned off, user song data saved
as Song Bank tunes are retained as long as power is being
supplied to the keyboard.
Unplugging the AC adaptor when batteries are not loaded
or when batteries are dead cuts off the power supply. This
causes all keyboard settings to be initialized to the initial
factory defaults, and clears all data stored in memory.
Power Requirements
Note the following precautions whenever you want to ensure
that current keyboard settings and memory contents are not
lost.
•Make sure the keyboard is being supplied power through
the AC adaptor before replacing its batteries.
•Before unplugging the AC adaptor, make sure that fresh
batteries are loaded in the keyboard.
Make sure that keyboard power is turned off before replacing
batteries or unplugging the AC adaptor.

Connecting Headphones (Figure 1
)
Connecting headphones cuts off output from the keyboard’s
built-in speakers, so you can play even late at night without
disturbing anyone.
Audio Equipment (Figure 2
)
Connect the keyboard to an audio equipment using a
commercially available connecting cord with a standard plug
on one end and two PIN plugs on the other end. Note that
the standard plug you connect to the keyboard must be a
stereo plug, otherwise you will be able to output only one of
stereo channels. In this configuration, you normally set the
input selector of the audio equipment to the terminal (usually
marked AUX IN or something similar) where the cord from
the keyboard is connected. See the user documentation that
comes with your audio equipment for full details.
Musical Instrument Amplifier (Figure 3
)
Use a commercially available connecting cord to connect the
keyboard to a musical instrument amplifier.
NOTE
•Be sure to use a connecting cord that has a stereo
standard plug on the end you connect to the keyboard,
and a connector that provides dual channel (left and
right) input to the amplifier to which you are connecting.
The wrong type of connector at either end can cause
one of the stereo channels to be lost.
When connected to a musical instrument amplifier, set the
volume of the keyboard to a relatively low level and make
output volume adjustments using the amplifier’s controls.

•With piano tones, depressing the pedal causes notes to
linger, much like a piano’s damper pedal.
•With organ tones, depressing the pedal causes notes to
continue to sound until the pedal is released.
Sostenuto Pedal
•As with the sustain pedal function described above,
depressing the sostenuto pedal causes notes to be sustained.
•This difference between a sostenuto pedal and sustain pedal
is the timing. With a sostenuto pedal, you press the keys
and then depress the pedal before you release the keys.
•Only the notes that are sounding when the pedal is
depressed are sustained.

•When one of the drum sets is selected (tone numbers
256 through 263), each keyboard key is assigned a
different percussion sound. See page A-4 for details.
Polyphony
The term polyphony refers to the maximum number of notes
you can play at the same time. The keyboard has 32-note
polyphony, which includes the notes you play as well as the
rhythms and auto-accompaniment patterns that are played
by the keyboard. This means that when a rhythm or auto-
accompaniment pattern is being played by the keyboard, the
number of notes (polyphony) available for keyboard play is
reduced. Also note that some of the tones offer only 16-note
polyphony.
•When rhythm or auto accompaniment is playing, the
number of sounds simultaneously played is reduced.
