For all TR jumps (except for 100TR jump), the track jump operation continues even after the key is
released. For the CRG Move and 100TR jump, the tracking closes at the same time when the key is released.
With the Power Off/On, the Jump Mode is reset to the Single TR(91).
Note: • If [TRACK UP] or [TRACK DOWN] key is pressed during Focus search, turn off the power
immediately to prevent the actuator's damage caused by the lens stuck.
After pressing the EJECT key, do not press any other key until the disk is completely ejected.
