The 'CHECK' message on your Pioneer Recording Equipment means that the source player was already playing when the SYNC button was pressed. To fix this, stop the source player. After a short time, SYNC–1 or SYNC–ALL will be displayed, and the recorder will enter synchro–record-pause mode.
What to do if my Pioneer PDR-W839 Recording Equipment says 'REC FULL'?
If your Pioneer Recording Equipment displays 'REC FULL', it means you can't record any further onto the disc. This happens either because the disc is full, or you've already recorded 99 tracks. The solution is to use a new disc or erase the CD–RW disc.
Why does my Pioneer PDR-W839 Recording Equipment display 'REPAIR'?
The 'REPAIR' message on your Pioneer Recording Equipment indicates that the device was turned off or unplugged after recording without ejecting the disc. As a result, the recorder couldn't save essential recording information to the disc. While 'REPAIR' is shown, the recorder will automatically check the recorded area and update track numbers and recording time data. This might take about 40 minutes for a fully recorded disc. Once the 'REPAIR' message disappears, you can finalize the disc or record further.
What to do if my Pioneer PDR-W839 Recording Equipment displays 'D.IN UNLOCK'?
If your Pioneer Recording Equipment shows 'D.IN UNLOCK', it signifies that the digital source was interrupted, isn't audio, or is an incompatible format like a CD–ROM. To resolve this, verify that the digital input cable is correctly connected and that the source player is powered on. Also, ensure that the source is a regular music source.
Why Pioneer PDR-W839 Recording Equipment says 'Can't REC'?
If your Pioneer Recording Equipment says 'Can't REC', it's because the input signal is digitally copy-protected with SCMS. A solution is to record the source through the analog inputs.
Why does my Pioneer PDR-W839 Recording Equipment say 'Pro DISC'?
The 'Pro DISC' message on your Pioneer Recording Equipment means that you've loaded a CD–R or CD–RW disc intended for professional use, which lacks the Consumer Use designation. To solve this, use a CD–R or CD–RW disc that is specifically marked for consumer use.
What to do if my Pioneer Recording Equipment says 'Can't SYNC'?
If your Pioneer Recording Equipment displays 'Can't SYNC', it means the digital source isn't recognized as a CD, MD, DVD, DAT, or DCC. If you're recording from a different source, try using the manual digital recording mode.
