temperature will rise. The power supply may shut down
automatically to protect the device from high temperatures.
Startup does not complete
In some cases, the KRONOS will not start up properly if
certain USB storage devices are connected. In this case,
disconnect the USB devices from the KRONOS, wait about
10 seconds, and then turn on the power again. You may be
able to solve the problem by formatting the USB device on
the KRONOS (see “Formatting media” on page 206).

The power is turned on, but the LCD screen does
not display normally, or an error message is
displayed. There is no sound when you play the
keyboard, and the KRONOS does not function
normally.

factory state.
HD-1 Program P0: Play page display

or other images representing the sound, or the
Overview/Jump graphics which show the settings of various
important parameters (such as EGs, LFOs, and so on).
