How to Use the Disc Locks

Locking and unlocking
The disc tray has four disc locks that prevent the disc from falling
when the drive unit is set up in vertical position.
Note:
When the drive unit is used in horizontal position, you do not need
to lock the disc.
All of the four locks are set in the unlocked position (facing
outward) when the drive is shipped from the factory. To set the lock
in the locked position, turn it with your fingers until you hear a click
so that it faces inward.
