Products from these brands have been testedand certified for use with the CDR 20. While discs from other brands may also work, we cannotguarantee proper operation of the unit when they are used.CD-R Audio Disc Manufacturers:TDK Electronics Corporation Maxell Corporation of AmericaLG Electronics, Inc.

When in doubt as to the origin of a disc, check with the brandshown on the package.When a CD Audio disc is recorded on a computer, it is often possible to record a set of tracks,finalize the disc, and then add additional tracks and finalize the disc again in a second recordingsession. This produces what is called a “multi-session” disc. Please note that these discs will workproperly when played back on a computer, or on the CDR 20’s Record (CDR) deck. However, dueto differences in the way CDs are played back on computers, as opposed to consumer CD Audioplayers, multi-session discs will NOT play back properly on the CDR 20’s Play (CDP) deck, or onmost consumer CD players. When a multi-session disc is played in the CDP deck, only the tracks inthe first session will play. This is not a defect or problem with the CDR 20, but is due to differencesin the formats between computer recordings and CD Audio products or commercially recorded CDs.The CDR 20 prohibits the track incrementing function during the first six seconds for each trackduring recording. Thus, if a source track is less than six seconds long, it will be recorded, but it willnot be assigned a track number. The track with less than six seconds will be combined into the nexttrack number that is recorded on the disc. This feature prevents the recording of empty tracks whenthe source signal was not cued up to start playing at the same time a recording session begins.
