This receiver has electronic technology using the IC bus concept. It performs as a control

individually, many of the control functions are now performedby using “on screen display
menu”. (The service adjustment mode.)

It is suggested that the technician reads all the way through and understand the following
procedure for entering/exiting the service adjustment mode; then proceed with the instructions
working with the receiver. When becoming familiarwith the procedure, the flow chart for
