PSR-E303/YPT-300 Owner’s Manual 9
Make all necessary connections BEFORE turning the power on.
The PSR-E303/YPT-300 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 an optional footswitch. Plug
the Yamaha FC4 or FC5 footswitch into this jack and
use it to switch sustain on and off.
The instrument also features MIDI terminals, allow-
ing you to interface the instrument with other MIDI
instruments or computers. (For more information, see
page 58.)
Turn down the volume by turning the [MASTER
VOLUME] control to the left and press the
[STANDBY/ON] switch to turn on the power. Press-
ing the switch again turns the power off.
Backup data in the flash memory (page 29) is loaded
to the instrument when the power is turned on. If no
backup data exists on flash memory, all instrument
settings are restored to the initial factory defaults
when the power is turned on.

•To prevent damage to the speakers, set the volume of the
external devices at the minimum setting and turn power
off the devices before connecting them. Failure to
observe these precautions may result in electric shock or
equipment damage. Also, be sure to set the volumes of all
