Roland RG-3 用户手册

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. 70).

Could you be using a connection cable that contains a resistor?
Use a connection cable that does not contain a resistor.

Do you have different external devices plugged into different power outlets?
When connecting external devices, always draw power from the same outlet.

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.

Try the following procedure. If after these steps you are still unable to get the CD to eject, read 
the CD drive owner’s manual.
1. Turn off the power to all connected devices.
2. Turn on the RG-3.
3. Turn on the CD drive.
4. Wait a few moments after the power is switched on, then firmly press the eject button.

Is the external display or television properly connected? (p. 45, p. 47)
Is the external display’s power turned on?
Are you using a display that is compatible with the RG-3? 
Refer to “Displays That Can Be Connected to This Instrument” (p. 45).
Is the television format or display setting correct? (p. 46, p. 47)

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-3.

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).

Is the volume level of the RG-3 (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 speaker stops playing.
Could the keyboard volume be turned down completely in the volume balance settings? 
(p. 72)
Could the levels of all frequency ranges be turned down completely in the equalizer settings? 
(p. 60)
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. 94).

Have all devices been switched on?
Are the MIDI cables connected correctly? (p. 99)
Does the MIDI channel match the connected instrument? (p. 100)

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. 100).

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.

Do you have the Layer tone selected? (p. 54)
When the RG-3 is connected to an external sequencer, set it to the Local Off mode (p. 100). 
Alternatively, the sequencer could be set so its Soft Thru feature is Off.
