them inside a car for extended periods may damage them and make playback impossible.
≥
The unit may not successfully play back a CD-R/RW that was made by the combination of writing software, a
CD recorder (CD-R/RW drive) and a disc if they are incompatible one another.
≥
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 data.
≥
Be sure to observe the instructions of CD-R/RW disc for handling it.
