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)

NOTE
When a CD-DA (regular music CD) is played in the CD test mode, its sound quality
[Key]
will be temporarily deteriorated. The CD will then repeat normal, deteriorated,
normal... playback.
Contents
This is due to the difference in the playback modes between the normal operation
Display
mode and the CD test mode, and the interval of generating deteriorated mode and
the time taken to return to the normal mode depend on the error of each clock.
The time taken to turn to the deteriorated mode is at a minimum around 20
seconds while the time to return to the normal mode is maximum 40 seconds
approximately.
