PX-600 Parasound IR Learning.doc 

OVERVIEW 

The IR bursts on Parasound remotes are short quick bursts.  If the button on the Parasound remote is held too 
long the px-600 programmer will lock up.  To avoid this from happening the button on the remote must be pressed 
and released quickly and then the volume up button press to fill up the IR. space inside the PX-600. 

LEARNING IR. CODES 

1.  Hold the remote in front of the IR. window on the programmer. 

2.  Press and release the button for the command being learned. 

3.  Press the VOLUME UP button and hold until programmer says STORAGE SUCCESSFUL. 

NOTE : For the volume up or down commands this step should be skipped. 

4.  Repeat the previous steps until all buttons IR. commands are learned
