Troubleshooting
Problems with Bluetooth Functionality
Problem Cause Page
Can’t connect with Bluetooth headphones or
speakers
Check whether the Bluetooth device is able to connect.
If the Bluetooth device is too far away from the R-07, it might be unable to connect.
Place the Bluetooth device near the R-07.
Check the R-07’s “Pairing Audio” to see whether pairing data might be lost.
If the data is lost, perform the pairing operation once again.
No sound from the Bluetooth headphones
or speakers
No sound is output if the R-07’s volume is set to “0.” Raise the R-07’s volume.
No sound is heard if you’ve lowered the volume of the Bluetooth headphones or
speakers. Raise the volume of the Bluetooth headphones or speakers.
Noise is heard from the Bluetooth
headphones or speakers
Noise might be heard if there is a nearby device that uses the same frequency range
(2.4 GHz) as the R-07. Move the R-07’ away from other devices that use the same
frequency range (2.4 GHz).
Noise might be heard if there is an obstruction such as a wall or person between the
R-07 and the Bluetooth device.
Use the R-07 in an unobstructed location with a clear line of sight. The distance at
which communication is possible might be shorter for some Bluetooth devices. Use
the Bluetooth device as near as possible to the R-07.
The R-07’s Bluetooth indicator remains
blinking
Depending on conditions, a Bluetooth device connected to the R-07 might be
disconnected. Power-on the Bluetooth device and reconnect it. If it does not
reconnect, use the R-07’s “Disconnecting a Bluetooth device” function to end the
connection, and then reconnect.
Can’t connect to the R-07 from an app
Delete the “Roland R-07 MIDI” that is registered on your mobile device; then re-
register and connect.
