Yamaha PSR-S710 User Guide

A click or pop is heard when the power is turned on or off.

Electrical current is being applied to the instrument. This is normal.

Noise is heard from the instrument’s speakers.

Noise may be heard if a mobile phone is used near the instrument or 

if the phone is ringing. Turn off the mobile phone, or use it further 
away from the instrument.

There is a slight difference in sound quality among different notes 
played on the keyboard.

This is normal and is a result of the instrument’s sampling system.

Some Voices have a looping sound.

Some noise or vibrato is noticeable at higher pitches, depending 
upon the Voice.

The overall volume is too low, or, no sound is heard.

The master volume may be set too low. Set it to an appropriate level 

with the [MASTER VOLUME] dial.

All keyboard parts are set to off. Use the PART ON/OFF [RIGHT 1]/
[RIGHT 2]/[LEFT] button to turn it on.

The volume of the individual parts may be set too low. Raise the vol-
ume in the BALANCE display (page 48).

Make sure the desired channel is set to ON (pages 47, 54).

Headphones are connected, disabling the speaker output. Unplug the 
headphones.

The [FADE IN/OUT] button is on, muting the sound. Press the [FADE 
IN/OUT] button to turn the function off.

The sound is distorted or noisy.

The volume may be turned up too high. Make sure all relevant volume 
settings are appropriate.

This may be caused by certain effects or filter resonance settings. 
Check the effect or filter settings and change them accordingly, 
referring to the Reference Manual.

Not all simultaneously played notes sound.

You are probably exceeding the maximum polyphony (page 104) of 

the instrument. When the maximum polyphony is exceeded, the earli-
est played notes will stop sounding, letting the latest played notes 
sound.

The keyboard volume is lower than the Song/Style playback vol-
ume.

The volume of the keyboard parts may be set too low. Raise the vol-
ume in the BALANCE display (page 48).

The Main display does not appear even when turning the power on.

This may occur if a USB storage device has been installed to the 

instrument. Installation of some USB storage device may result a long 
interval between turning the power on and appearance of the Main 
display. To avoid this, turn the power on after disconnecting the 
device.

Some characters of the file/folder name are garbled.

The language settings have been changed. Set the appropriate lan-

guage for the file/folder name (page 16).

An existing file is not shown.

The file extension (.MID, etc.) may have been changed or deleted. 
Manually rename the file, adding the appropriate extension, on a 
computer.

Data files with names of more than 50 characters cannot be handled 
by the instrument. Rename the file, reducing the number of charac-
ters to 50 or less.
