Problem
Possible Cause and Solution
When the PSR-280 is turned on or off, a popping
sound is temporarily produced.
This is normal and indicates that the PSR-280 is receiving electrical
power.
When using a mobile phone, noise is produced.
Using a mobile phone in close proximity to the PSR-280 may produce
interference. To prevent this, turn off the mobile phone or use it fur-
ther away from the PSR-280.
There is no sound even when the keyboard is
played or when a song is being played back.
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.
Playing keys in the right hand section of the key-
board does not produce any sound.
When using the Dictionary function (page 45), the keys in the right
hand section are used only for entering the chord root and type.
The sound of the voices or rhythms seems unusu-
al or strange.
The battery power is too low. Replace the batteries. (See page 8.)
The auto accompaniment doesn’t turn on, even
when pressing the [ACMP ON/OFF] button.
Make sure the Style mode is active before using the auto accompa-
niment. Press the [STYLE] button to enable style operations.
The accompaniment or song does not play back
even when pressing the [START/STOP] button.
When External Clock (page 70) is set to “on,” style playback CAN-
NOT be controlled from the PSR-280 panel controls.
The accompaniment does not sound properly.
Make sure that the Accompaniment Volume (page 41) is set to an ap-
propriate level.
Make sure that the Split Point (page 44) is set to an appropriate value.
When playing back one of the Pianist styles (#086
- #100), the rhythm cannot be heard.
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 section of the keyboard.
Not all of the voices seem to sound, or the sound
seems to be cut off.
The PSR-280 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 “stolen”)
from the accompaniment or song.
A strange “flanging” or “doubling” sound occurs
when using the PSR-280 with a sequencer. (This
may also sound like a “dual” layered sound of two
voices, even when Dual is turned off.)
When using the accompaniment with a sequencer, set MIDI Echo (or
the relevant control) to “off.” (Refer to the owner’s manual of your par-
ticular device and/or software for details.)
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 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 sound of the voice changes from note to note.
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.
