With the AC power adaptor connected or 
with batteries installed, simply press the 
power switch until it locks in the ON posi-
tion.  When the instrument is not in use, be 
sure to turn the power off.  (Press the switch 
again so that it pops up.)

For private practicing and playing without dis-
turbing others, connect a set of stereo headphones 
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.
 Connecting a Keyboard Amplifier or Stereo System  • • • • • • •
Though the PSR-290 is equipped with a built-in 
speaker system, you can also play it through an 
external amplifier/speaker system.  First, make 
sure the PSR-290 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 PSR-290.
 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.
 Using the MIDI Terminals  • • • • • • • • • • • • • • • • • • • • • • • • • • •
The PSR-290 also features MIDI terminals, 
allowing you to interface the PSR-290 with other 
MIDI instruments and devices.  (For more infor-
mation, see page 67.)
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-290 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.
•  Never attempt to turn the power off when a “WRITING!” 
message is shown in the display. Doing so can damage 
the internal flash memory and result in loss of data. 
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.
