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.) • 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-275/273 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 I 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. I Connecting a Keyboard Amplifier or Stereo System Though the PSR-275/273 is equipped with a built-in speaker system, you can also play it through an external amplifier/speaker system. First, make sure the PSR-275/273 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 Stereo System jack on the PSR-275/273. I Using a Footswitch This feature lets you use an optional 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. I Using the MIDI Terminals The PSR-275/273 also features MIDI terminals, allowing you to interface the PSR-275/ 273 with other MIDI instruments and devices. (For more information, see page 55.) • 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. • Make sure that the footswitch plug is properly connected to the SUSTAIN 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 11

Turning On the Power
• Even when the switch is in the “STANDBY” position,
electricity is still flowing to the instrument at the mini-
mum level. When you are not using the PSR-275/273 for
a long time, make sure you unplug the AC power adap-
tor from the wall AC outlet, and/or remove the batteries
from the instrument.
Accessory Jacks
Stereo System
•
To prevent damage to the
speakers, set the volume of the
external devices at the mini-
mum setting before connect-
ing 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 grad-
ually raise the volume controls
while playing the instrument to
set the desired listening level.
• Make sure that the footswitch
plug is properly connected to the
SUSTAIN 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.
