Setting Up
Be sure to do the following operations BEFORE turning on the power.
Make sure that the [STANDBY/ON] switch of the
instrument is set to STANDBY.
Connect the AC adaptor to the power supply jack.
Plug the AC adaptor into an AC outlet.
Make all necessary connections below BEFORE turning the power on.
The instrument 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/OUTPUT 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.
The sustain function lets you produce a natural sustain
as you play by pressing a footswitch. Plug the Yamaha
FC5 footswitch into this jack and use it to switch sustain
on and off.
Power Requirements
• Use the specified adaptor (PA-5D or an equivalent recom-
mended by Yamaha) only. The use of other adaptors may
result in irreparable damage to both the adaptor and the
instrument.
WARNING
• Unplug the AC Power Adaptor when not using the instrument,
or during electrical storms.

Connecting Headphones (PHONES/OUTPUT Jack)
• Avoid listening with the headphones at high volume for long peri-
ods of time; doing so may not only result in ear fatigue, it may be
damaging to your hearing.
WARNING
• To prevent damage to the speakers, set the volume of the external
devices at the minimum setting before connecting them. Failure to
observe these cautions may result in electric shock or equipment
damage. Also, be sure to set the volumes of all devices at their
minimum levels and gradually raise the volume controls while
playing the instrument to set the desired listening level.
CAUTION
Connecting a Footswitch (SUSTAIN Jack)
• Make sure that the footswitch plug is properly connected to the SUS-
TAIN 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, resulting in reversed
footswitch operation.
