To get into the emergency recovery system, you need to:

  • Switch off all graphic data output devices (TV, projectors, monitors).
  • Connect one main monitor to display the recovery system interface.


*If several graphic data output devices (TV, monitors, etc.) are connected to the karaoke system, then the recovery system boot selection menu will be displayed on one of the devices connected to different video outputs. The display devices will have the following priority:

  • DVI
  • HDMI
  • VGA


For example: if two display devices (TV and monitor) are connected to the karaoke system video outputs: the VGA output (monitor) and the HDMI one (TV), the boot menu will be displayed on the TV connected to the HDMI output.

  • Switch on the karaoke system using the power button on the front panel.
  • Immediately after you see the first boot image, press and hold the left Shift key on the keyboard until the karaoke system boot selection menu is displayed.

* If the boot menu is not displayed, you have to switch off and then to switch on the karaoke system again, and to repeat the procedure.
