Power does not turn on
Is the power cord connected correctly?
Nothing appears in the screen

graphics appear in the screen if the temperature is below zero degrees Celsius
(32 degrees Fahrenheit).

Touch panel does not respond
correctly
The touch panel position may drift due to changes in the environment or the
passage of time. Correct the drift as described in “Calibrating the Touch
Screen (Touch Screen).”

Press the [VIDEO MONITOR] button or the [EXIT] button so the [VIDEO
MONITOR] button is turned off.

location, the song list will not appear.
The song list will not appear if you select “Ext Memory” or “CD” as the song
location when USB memory or the CD-ROM do not contain any songs.
You won’t be able to select “Ext Memory” or “CD” as the song location if USB
memory is not connected or if no CD-ROM is inserted in the CD drive.
