Optical disc compatibility
This unit is compatible with a wide range of available optical 
discs for recording and playback. 
Hold a disc by the rim or with an index finger in the central
hole. Never touch the signal surface.
Finger prints or stains on the surface of the disc may cause 
signal loss. 
Use a soft cloth and wipe in a radiating manner from the 
center of the disc to the outer rims when cleaning the disc 
surface.
Never add labels or adhesive tapes on the discs and be 
careful not to scratch or damage the disc surface.
To prevent discs from becoming bent or deformed, they 
should be vertically kept in the disc storage case. To prevent 
damage, avoid leaving discs in your car, where they may be 
subject to direct sunlight and high temperature. 
Do not use any disc accessory to improve the audio quality, 
disc protective solutions or lens cleaner. These products may 
damage the disc surface.

Discs suitable for Recording and Playback
DVD Video: This unit plays DVDs recorded for a particular 
region. The region mark on the back of the player must 
correspond to that on any DVD discs you wish to play. Units 
sold in North America are coded for Region 1, and are 
compatible with discs marked accordingly.
You must us DVD+R or DVD+RW discs to record on this unit.
DVD+R: These discs can only be written to once. Existing 
recordings can be hidden but not deleted. So, any disc space 
already used by a recording cannot be regained. DVD+R discs 
are required to be "Finalized" before they will be compatible 
with standard DVD Players. Once a disc is finalized, no further 
recordings can be made.
DVD+RW: DVD+RW discs can be written to and erased 
multiple times. Existing recordings can be deleted and disc space 
regained. These discs do not require a finalization procedure. As 
soon as a recording is made, the disc will be compatible with 
standard DVD Players.
