* 1 ... When Focus Search operates continuously more than 10 minutes, the protection circuit is activated due to heat generation of the driver IC.
In this case, turn off the power, wait for approximately 10 minutes so that heat is released, and then restart.
* 2 ... When Focus Search fails three times, the gain is switched for CD-RW at 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 pickup is located in
