Setting Up Turning On the Power With the AC power adaptor connected or with batteries installed, simply press the power switch until it locks in the ON position. When the instrument is not in use, be sure to turn the power off. (Press the switch again so that it pops up.) CAUTION • Even when the switch is in the "STANDBY" position, electricity is still flowing to the instrument at the minimum level. When you are not using the PSR-450 for a long time, make sure you unplug the AC power adaptor from the wall AC outlet, and/or remove the batteries from the instrument. Accessory Jacks ■ Using Headphones For private practicing and playing without disturbing others, connect a set of stereo headphones to the rear panel PHONES/OUTPUT jack. Sound from the built-in speaker system is automatically cut off when you insert a headphone plug into this jack. ■ Connecting a Keyboard Amplifier or Stereo System Though the PSR-450 is equipped with a built- in speaker system, you can also play it through an external amplifier/speaker system. First, make sure the PSR-450 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 Stereo System PSR-450. ■ Using a Footswitch This feature lets you use a footswitch (Yamaha FC4 or FC5) to sustain the sound of the voices. 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. ■ Using the MIDI Terminals The PSR-450 also features MIDI terminals, allowing you to interface the PSR-450 with other MIDI instruments and devices. (For more information, see page 64.) CAUTION • 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. NOTE • 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. MIDI instrument PSR-450 Owner's Manual 11

Even when the switch is in the “STANDBY” position,
electricity is still flowing to the instrument at the
minimum level. When you are not using the PSR-450
for a long time, make sure you unplug the AC power
adaptor from the wall AC outlet, and/or remove the

CAUTION
•
To prevent damage to the
speakers, set the volume of
the external devices at the
minimum setting before con-
necting 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 lev-
els and gradually raise the
volume controls while play-
ing the instrument to set the
desired listening level.
CAUTION
Stereo System
•
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 recog-
nized polarity of the footswitch,
resulting in reversed footswitch
operation.
