This set is a component of the MHC-S7AV, MHC-SV7AV and
MHC-S3.
The MHC-S7AV/SV7AV/S3 system configuration is as shown be-
low, and therefore it does not operate normally unless all four com-
ponents are connected.
In performing the repair, connect all components with the system
cables.
Note: The precaution to the users is described on the label stuck on
the back panel (CD player) and in the troubleshooting section in
the Operation Manual.
