Troubleshooting
Symptom
Power does not turn on.
No sound from the BK-5 OR.
The volume level of the instrument is too low
when it is connected to an amplifier.
The pitch of the selected rhythm/song is incorrect. Is the "Tuning" setting appropriate?

Can't hear the melody of SMF files.
A "buzz" is heard from the external amplifier

Backing Keyboard BK-5 OR
Action
Is the included AC adaptor/power cord correctly connected to an
AC outlet and to the BK-5 OR?
Do not use any AC adaptor or power cord other than the ones
included. Doing so will cause malfunctions.
Did you switch the BK-5 OR on?
Could the [VOLUME] knob be turned down? Select a higher set-
ting.
Can you hear sound through headphones?
If you can hear sound through headphones, it may be that the
connection cables are broken, or that your amp or speaker has
malfunctioned. Check the cables and your equipment once again.
Could the part volume settings have been minimized?
Check the "Volume" setting of each part.
Could a MIDI message received from an external MIDI device (vol-
ume message or exclusive message) have lowered the volume?
Could you be using a connection cable that contains a resistor?
Use a connection cable that doesn't contain a resistor.
Did you transpose the rhythm/song? Also check the "Rhythm
Scale Tune" parameter.
If the [TRACK MUTE] (CENTER CANCEL) button is lit, the vocal
sound will be attenuated.
If the [TRACK MUTE] button is lit, the melody of the MIDI files will
be muted. Switch it off.
Is the external amplifier or other device used with the BK-5 OR
connected to a different AC power outlet?
Connect the amplifier or other device to the same AC outlet as the
BK-5 OR.
Is the song in a format that the BK-5 OR is able to read?
The BK-5 OR may be receiving on a MIDI channel on which the
MIDI controller doesn't transmit. Correct the MIDI controller's
transmit channel.
Are you using an (optional) Roland USB memory (M-UF series)?
Reliable performance cannot be guaranteed if you use non-
Roland USB memory products.
Check the format of your USB memory. The BK-5 OR can use USB
memory that has been formatted as FAT. If your USB memory was
formatted using any other method, please re-format it using the
BK-5 OR.
Could the USB memory be write protected?
Is there sufficient free space on the USB memory?
