*Report commands are divided into following three types.

System state report:

This report command informs the system state, such as busy,

when it changes.

Playback state report:

This report command informs the RX-V1's internal playback state

and Fs of source, when the source signal changes.

Operation report:

This report command informs the last state of the setting which is

controlled by I/R, RS-232C, or keys, when the transactions are

completed.

*RX-V1 reports the "Power Off" report (System state report), when a

control command except for the Ready, Power control, and System

command is sent to RX-V1.

*RX-V1 reports the Guard status, which indicates if transaction is

prohibited or not, and what is prohibiting the transaction when the guard is

on.

*RX-V1 send only one Report command for each types of control after the

control command is sent to RX-V1, which reports the last state of the

setting as a result of the series of transactions.

For example, If a user set the input selector in the unit to LD just after the

host send commands to change input to CD, RX-V1 report only that the

input was changed to LD by the system operation.
