*1: The driver IC heats up and the protection circuit starts working when the focus search is continued for 10 minutes or longer.
There can be a case that operations cannot be performed correctly. In such a case, turn off the main power. After cooling down
the machine, restart the machine.
*2: Be careful not to damage the gear because the sled motor rotates while the FF or RWD button is being pressed even if the
pickup is located in the innermost track or the outermost track.
