■ Using the MIDI Terminals
• Make sure that the footswitch plug is properly connected to
the FOOT SWITCH 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.

ACCESSORY JACKS
■ Using Headphones
For private practicing and playing without
disturbing others, connect a set of stereo head-
phones to the rear panel PHONES/OUTPUT jack.
Sound from the built-in speaker system is auto-
matically cut off when you insert a headphone
plug into this jack.
FOOT SWITCH
■ Using a Footswitch
This feature lets you use an optional footswitch
(Yamaha FC4 or FC5) to sustain the sound of the
voices, or control a variety of other functions.
(See page 91.) When this is used for sustain, the
footswitch functions the same way as a damper
pedal on an acoustic piano — press and hold
down the footswitch as you play the keyboard
to sustain the sound.
■ Connecting a Keyboard Amplifier or Stereo
System
Though the PortaTone is equipped with a built-
in speaker system, you can also play it through
an external amplifier/speaker system. First,
make sure the PortaTone and any external
devices are turned off, then connect one end of
a stereo audio cable to the LINE IN or AUX IN
jack(s) of the other device and the other end to
the rear panel PHONES/OUTPUT jack on the
PortaTone.
PHONES/
OUTPUT
The PortaTone also
features MIDI termi-
nals, allowing you to
interface the
PortaTone with other
MIDI instruments and
devices. (For more
information, see
pages 20, 93.)

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.
