FOOTSWITCH jack

The sustain function lets you produce a natural
sustain as you play by pressing a footswitch. Plug
an optional Yamaha FC4 or FC5 footswitch into
this jack and use it to switch sustain on and off.
The footswitch connected to this jack can also be
set to replicate the functions of some panel buttons,
doing things like starting and stopping accompani-
ment (page 121).
• Be sure that you do not press the footswitch while turning the power
on. If you do, the ON/OFF status of the footswitch will be reversed.
• When the sustain or sostenuto pedal functions are being used
(page 121), some voices may sound continuously or have a long
decay after the notes have been released while the pedal is held.

PHONES/OUTPUT jack

A standard pair of stereo headphones can be
plugged in here for private practice or late-night
playing. The internal stereo speaker system is
automatically shut off when a pair of head phones is
plugged into the PHONES/OUTPUT jack.
Do not listen with the headphones at high volume
for long periods of time. Doing so may cause
hearing loss.
CAUTION
• Connect the PSR-550 to external equipment only after
turning off power for all devices. 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.
