Action
For some types of music files, the lyrics may sometimes be displayed incorrectly. Some words may be
incorrectly shown outside the screen display area.
Could you be using a connection cable that contains a built-in resistor? Use a connection cable that
does not contain a resistor.

Press the [TRACK MUTE] (CENTER CANCEL) button to make its indicator go dark.
The file type of the song is not one of the file types that the BK-9 can play.
It may be that the song data is damaged.
If you use forward and rewind ([ENDING] / [& ] and [INTRO] / [' ] buttons) during a playback of mp3
file with a variable bit rate (VBR), this message could appear. It's a temporary synchronization failure.
You don't need to take any action.
The USB memory doesn't contain any Performance List files.
For some reason the USB memory is not recognized.
Use (optional) Roland USB memory (M-UF series).
• Make sure that your wireless LAN access point supports WPS.
If your wireless LAN access point does not support WPS, you can connect using the procedure
described in "Connecting to a Wireless LAN Access Point That You Select" (p. 163).

on the power, check and make sure the setting described in "Connecting in Ad-Hoc mode" (p.
164) is OFF.
• There is a limit to the connection data that can be remembered. Making a new connection may
cause older connection data to be deleted.

may be dropouts in the audio.
The following actions may improve the situation.
• Move the wireless LAN access point and the BK-9 closer to each other.
• Change the channel setting of the wireless LAN access point.
• Is the BK-9 powered up?
• Is the wireless USB adapter (WNA1100-RL) inserted to the BK-9?
• Is the BK-9 connected to the wireless LAN?
• Are the BK-9 and the iPhone connected to the same network (the same wireless LAN access
point)?
• Is the wireless LAN access point set to allow communication between wireless LAN devices?
For details on settings, refer to the owner's manual of your wireless LAN access point.
• Is the wireless LAN access point connected to the Internet?
• Could you be connected in Ad-Hoc mode?
The iPod touch or other wireless device connected in Ad-Hoc mode will be unable to
communicate with the Internet or with another wireless device. However, an iPhone or other
wireless device that has cellular capability will be able to connect to the Internet via the cellular
connection. Please be aware that if you use a cellular connection for Internet connectivity, you
may incur costs depending on your rate plan.
A wireless device such as an iPod touch that does not have cellular capability will become unable
to connect to the Internet in this case.
