• As for the double speed (2x), audio output cannot be supported
www
*) • 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).
.
• In the case of TR jump other than to 100TR, the function shall continue to be processed even if the TR jump key is released. As for
the CRG Move and 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 jump mode is reset to the Single TR (91) while 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.
