If you have any questions or problems
concerning your recorder, please consult your
nearest Sony dealer. (If a trouble occurred when
the disc was in the recorder, we recommend that
the disc be left in the recorder when you consult
your Sony dealer so that the cause of trouble
may be better understood.)
