After the [EJECT] key is pressed keys other than the [EJECT] key should not be pressed, until disc ejection is complete.
When the key [UP] or [DOWN] 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).
In the case of 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.
F
Do not do Tracking Servo Close before doing Focus Servo Close. (Because the overcurrent flows)
