Problem
The Song title is not correct.
Menu display cannot be
called up.
Rhythm does not start.
The contents of the Wireless
LAN is not shown in the
display even though the USB
wireless LAN adaptor is
connected.
The Bluetooth-equipped
smart device cannot be
paired with nor connected to
the instrument.
Sound input via the [AUX IN]
jack or Bluetooth is
interrupted.
*For information on whether Bluetooth functionality is included or not, refer to page 8.
The "Language" setting may be different than that is selected when you named the Song. Also, if the Song was
recorded on another instrument, the title might be displayed incorrectly. Set the "Language" parameter
(page 102) via the "System" menu display: "Utility"  "Language"  "Song" to change the setting. However, if
the Song was recorded on another instrument, changing the "Language" parameter setting may not resolve the
problem.
When Song is being played back, menu display other than "Voice" menu and "Song" menu will not appear. Stop
the Song by pressing the [PLAY/PAUSE] button. Also, in the recording ready mode, only "Recording" menu
display will appear.
"SynchStart" setting is on. Set "SynchStart" off in the "Metronome/Rhythm" menu display.
Disconnect the USB wireless LAN adaptor and connect it again.
Check the Bluetooth function of the smart device is activated. To connect the smart device and the instrument
via Bluetooth, both devices need to be functional.
The smart device and the instrument need to be paired to connect each other via Bluetooth (page 8).
In case there is a device (microwave oven, wireless LAN device, etc.) that outputs signals in the 2.4 GHz
frequency band nearby, move this instrument away from the device that is emitting radio-frequency signals.
The Noise Gate function of this instrument cuts unwanted noise from the input sound. However, this may result in
wanted sounds also being cut, such as the soft decay sound of a piano. This is normal and not a sign of
malfunction.
