After the [EJECT] key is pressed keys other than the [EJECT] key should not be pressed, until disc ejection is complete.
When the key [2] or [3] is pressed during the Focus Search, the power supply should be immediately turned off (otherwise the lens sticks
to Wall, causing the actuator to be damaged).
.
100TR Jump, the mechanism shall be set to the Tracking Close mode when the key is released.
When the power is turned on/off the gain of the RFAMP is reset to 0 dB. At the same time all the self-adjusting values shall return to the
default setting.
Do not do Tracking Servo Close before doing Focus Servo Close. (Because the overcurrent flows)
