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 101) 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.
This occurs infrequently when Grand Expression Modeling is set to "Dynamic."
If this happens, set Grand Expression Modeling to "Static" (page 29).
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 so that the instrument receives audio data from the smart
device via Bluetooth (page 78).
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.
