Yamaha PSR-125 Manual Do Utilizador

When the PortaTone is turned on or off, a buzzing sound

is temporarily produced.

The sound of the voices or rhythms seems unusual or

strange.

Not all notes are heard when playing a number of notes

simultaneously.

The sound of the Voice changes from note to note.

The power cannot be turned on.

This is normal and indicates that power is flowing into

the PortaTone.

The battery power is too low.  Replace the batteries.

Too many keys are pressed at the same time.  The

PortaTone is polyphonic up to a maximum of 12 notes.

(See the note on page 8.)

The AWM tone generation method uses multiple

recordings (samples) of an instrument across the range

of the keyboard; thus, the actual sound of the Voice may

be slightly different from note to note.

Quick, successive pressing of the STANDBY/ON button

may fail to turn the power on.  When using the

STANDBY/ON button, wait a short time between

successive presses.
