You can confirm the approximate amount of remain-
ing battery power at the top left of the display.

Connecting Headphones or
External Audio Equipment

Any pair of stereo headphones with a 1/4” stereo
phone plug can be plugged in here for convenient
monitoring. The speakers are automatically shut off
when a plug is inserted into this jack.
The PHONES/OUTPUT jack also functions as an
external output. You can connect the PHONES/OUT-

PUT jack to a keyboard amplifier, stereo system,
mixer, tape recorder, or other line-level audio device
to send the instrument’s output signal to that device.

Connecting a Footswitch to the
SUSTAIN jack

You can produce a natural sustain as you play by
pressing an optional footswitch plugged into the
[SUSTAIN] jack. Although the footswitch works as
the Sustain pedal for most Voices, it features other
functions such as Sostenuto and Arpeggio Hold (for
Voices 242–287). One of these functions can be
assigned to the footswitch on the Function display
(page 50).

Indicates that the power will be turned off
immediately. When rechargeable batteries are
used, this icon flashes before the power is
turned off.

Indicates that remaining power is insufficient
for operation. Before the power runs out,
replace all the batteries with new ones, or fully
recharged ones (when using rechargeable
types). Note that the instrument may not work
properly, including unusually soft volume and
poor sound quality when remaining power
becomes low.

Indicates that the remaining power is suffi-
cient.

Only one of these is shown.

Harmnum1

• Do not use the instrument/device or headphones for a long

period of time at a high or uncomfortable volume level,
since this can cause permanent hearing loss. If you experi-
ence any hearing loss or ringing in the ears, consult a phy-
sician.

• Before connecting the instrument to other electronic com-

ponents, set all volume levels to the minimum, then turn
off the power for all components.

• When the instrument’s sound is output to an external

device, first turn on the power to the instrument, then to
the external device. Reverse this order when you turn the
power off.

• When Split is on, the sustain function does not affect the cur-

rent Split Voice (page 17) while sostenuto and Arpeggio Hold
(page 39) affect only the current Split Voice.

• Make sure that the footswitch plug is properly connected to

the SUSTAIN jack before turning on the power.

• Do not press the footswitch while turning the power on. Doing

this changes the recognized polarity of the footswitch, result-
ing in reversed footswitch operation.
