b. Remove 3 screws (
!0
) and then remove the AM/FM Tuner in Fig. 4.
c. Remove 2 screws (
!1

and 5.
g. Place the INPUT (1)/(2) P.C.B. as shown in Fig. 6 and check them for operation.
Note :
When DSP P.C.B., INPUT (1) P.C.B., OPE (2)/(3)/(5) P.C.B., and AM/FM TUNER have been
removed from the rear panel, the ground connection becomes open. Connect the ground of
each P.C.B. to the chassis by using a lead wire.
