TEXT
¡You may have trouble playing back some CD-R/RW discs recorded on CD recorders (CD-R/RW drives), either due
to their recording characteristics or dirt, fingerprints, scratches, etc. on the disc surface.
¡CD-R/RW discs are less resistant to high temperatures and high humidity than ordinary music CDs. Leaving them
inside a car for extended periods may damage and make playback impossible.
¡Some CD-R/RWs can not be played back successfully thanks to incompatibility among writing software, a CD
recorder (CD-R/RW drive) and the discs.
¡This player cannot play the CD-R/RW discs if the session is not closed.
¡This player cannot play the CD-R/RW discs which contains other than CD-DA or MP3/WMA data.
¡Be sure to observe the instructions of CD-R/RW disc for handling it.
Notes on CD/CD Media (CD-ROM, CD-R, CD-RW)
Your product is designed and manufactured to ensure the minimum of maintenance. Use a soft cloth for
routine exterior cleaning. Never use benzine, thinner, or other solvents.
