*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 can not be performed correctly.
In such a case, turn off the main power. After cooling down the machine, restart the machine.
*2: After the focus search is executed three times, the gain is changed to the CD-RW gain from the fourth time.
*3: Be careful not to damage the gear because the sled motor rotates while the FF or RWD button is being pressed even if the pick-up
is located in the innermost track or the outermost track.
