Troubleshooting

When the PSR-275/273 is turned on or off, a pop-
ping sound is temporarily produced.
When using a mobile phone, noise is produced.
There is no sound even when the keyboard is
played or when a song is being played back.
Playing keys in the right hand area of the keyboard
does not produce any sound.
The sound of the voices or rhythms seems unusu-
al or strange.
The auto accompaniment doesn't turn on, even
when pressing the [ACMP ON/OFF] button.
The style or song does not play back even when
pressing the [START/STOP] button.
The style or song does not sound properly.
When playing back one of the Pianist styles (#93 -
#100), the rhythm cannot be heard.
Not all of the voices seem to sound, or the sound
seems to be cut off.
A strange "flanging" or "doubling" sound occurs
when using the PSR-275/273 with a sequencer.
(This may also sound like a "dual" layered sound
of two voices, even when Dual is turned off.)
The footswitch (for sustain) seems to produce the
opposite effect. For example, pressing the foot-
switch cuts off the sound and releasing it sustains
the sounds.
The sound of the voice changes from note to note.

Problem Possible Cause and Solution
This is normal and indicates that the PSR-275/273 is receiving elec-
trical power.
Using a mobile phone in close proximity to the PSR-275/273 may pro-
duce interference. To prevent this, turn off the mobile phone or use
it further away from the PSR-275/273.
Check that nothing is connected to the PHONES/OUTPUT jack on
the rear panel. When a set of headphones is plugged into this jack,
no sound is output.
Check the Local Control on/off or PC Mode on/off. (See page 57, 58.)
When using the Dictionary function (page 42), the keys in the right
hand area are used only for entering the chord root and type.
The battery power is too low. Replace the batteries. (See page 10.)
Make sure the Style mode is active before using the auto accompa-
niment. Press the [STYLE] button to enable style operations.
Check the External Clock on/off. (See page 57.)
Make sure that the Style Volume or Song Volume (page 39) is set to
an appropriate level.
This is normal. The Pianist styles have no drums or bass — only pi-
ano accompaniment. The accompaniment of the style can only be
heard when accompaniment is set to ON and keys are played in the
auto accompaniment area of the keyboard.
The PSR-275/273 is polyphonic up to a maximum of 32 notes. If the
Dual voice or Split voice is being used and a style or song is playing
back at the same time, some notes/sounds may be omitted (or "sto-
len") from the accompaniment or song.
When using the style with a sequencer, set MIDI Echo (or the relevant
control) to "off." (Refer to the owner's manual of your particular de-
vice and/or software for details.)
The polarity of the footswitch is reversed. Make sure that the foot-
switch plug is properly connected to the SUSTAIN jack before turning
on the power.
The AWM tone generation method uses multiple recordings (sam-
ples) of an instrument across the range of the keyboard; thus, the ac-
tual sound of the voice may be slightly different from note to note.
