Important Note: Since the CDR 20 is a dual-deck player/recorder, there are two separate sets of indicators for the Random, Program, Repeat, Repeat
Status, Time, Total Time and Track Time. In addition, there is a separate Information Display, Play/Pause Indicator and CD Indicator for each deck. As the
function of these indicators is identical for both decks, they are described in this manual with a common letter. When the CDR 20 is playing or recording a
disc, any indicators that light on the left side of the display describe the status of the Play Deck, while those that light on the right side of the display
describe the status of the Record Deck. Depending on the activity of the unit and the settings you select, different indicators may light on the two sides at
the same time.
