SET MODE**

**The SET MODE command allows the user to set a specific audio decode mode using RC 5 commands. The code is set by sending the unit the SET MODE command, then the two DIGIT commands which define the mode. These three commands must occur in sequence; any command sent after the SET MODE command, other than the DIGIT commands, causes the SET MODE sequence to be reset. Refer to the list of audio decode modes on page 20. Modes that do not apply to the current input stream are ignored.
