PROBLEM TO BE SOLVED: To provide a communication KARAOKE device which can download new music and enables continuous operation without connecting a telephone line all the times. SOLUTION: It is possible to make a choice between on-line operation for downloading music data, gathering a log, and receiving a reset signal for an operation permission timer on-one from a maintenance center 1 through the telephone line and off-line operation for downloading the music data, gathering the log, and receiving the reset signal for the operation permission timer from this copy terminal device. When the off-line operation is selected, the maintenance center 1 indicates maintenance to the copy terminal device without calling the KARAOKE device. |
