900K uses our Company’s GV-73 remote control. Press the lower right corner recording button in DVD mode, input the song number, pitch, and song name in sequence to complete the recording of this song. If it still doesn’t self-record, there are several possible issues. 1. The dealer added songs by copying and pasting, which caused the Company’s self-recording program to disappear and made it unable to self-record; 2. The VCD format is not compatible with the data; 3. DVD ROM malfunction reading failure; 4. Image decompression board failure or the program is too old; 5. This is an original encrypted anti-copy VCD which may cause it to not self-record. If you cannot troubleshoot the problem, please send it to a Service Center.
