Case
Cause/Remedy
 
The power doesn’t come on
 
 
Depressing a pedal has no 
effect, or the pedal effect 
doesn’t stop
 
Is the pedal connected correctly?
Make sure the pedal cord is securely connected to the pedal connector (p. 19).
Has a different function been assigned to the pedal?
See “Assigning Functions to Pedals” (p. 72).
 
The volume level of the in-
strument connected to Input 
jacks is too low
 
Could you be using a connection cable that contains a resistor?
Use a connection cable that does not contain a resistor.
 
Low hum coming from 
external device
 
Do you have different external devices plugged into different power outlets?
When connecting external devices, always draw power from the same outlet.
 
Unable to load properly with 
USB memory
 
Is the USB memory you are using one that was produced by Roland? 
Performance is not guaranteed when other types of USB memory are used.
 
Connected Television or External Display Screen Looks Odd
 
Images not shown on external 
display or television when 
external display or television 
is connected
 
 
Thin horizontal lines visible 
in the television screen
 
While narrow horizontal lines may be visible in the television screen, this is a particular char-
acteristic of the television set and does not indicate any problem with the RG-3M.
 
Poor-quality of images 
displayed in television
 
Even when all recommended settings are used, images may still not be displayed well with 
the television set you are using (images may not match the screen size, and may be clustered 
towards the center of the screen).
 
No sound is heard
 
No sound is heard
 
Is the volume level of the RG-3M (p. 20) or connected device turned all the way down?
Are headphones plugged in? (p. 21) Has a plug remained connected to the Phones jack? 
When headphones or plugs are connected, the keyboard’s speakers stop playing.
Could the keyboard volume be turned down completely in the volume balance settings? 
(p. 74)
Could the levels of all frequency ranges be turned down completely in the equalizer settings? 
(p. 62)
Is V-LINK switched on? While V-LINK is switched on, no sound is produced when you press 
any of the twelve keys at the left end of the keyboard (p. 98).
 
No sound is heard 
(when a MIDI instrument is 
connected)
 
 
No sound is heard when the 
keyboard is played
 
Has Local Control been set to “Off”? 
When Local Control is set to Off, no sound is produced by playing the keyboard. Set Local 
Control to On (p. 107).
 
Not all played notes are 
sounded
 
The maximum number of notes can play simultaneously is 128. 
Frequent use of the damper pedal during playing along with a song may result in perfor-
mance data with too many notes, causing some notes to drop out.
 
The sound is strange
 
Sounds are heard twice (dou-
bled) when the keyboard is 
played
 
 
The tuning or pitch of the 
keyboard or song is off
 
 
Reverberation still audible 
even with Reverb turned off
 
Since the RG-3M’s piano sounds accurately reproduce the depth and reverberation of the orig-
inal acoustic piano, you may find that reverberation is audible when the Key Off Resonance 
function is enabled. If you want to eliminate the reverberation, turn off the Key Off Resonance 
function (p. 59).
