The MOON 850P is equipped with a rear mounted 
IR input for use with aftermarket wired infrared 
remote control receivers. In the event that you want 
control the MOON 850P with a universal remote 
control and 
NOT the one included (FRM-3), you can 
change the RC-5 remote control system codes. This 
procedure is recommended when you have a large 
custom install setup that uses multiple integrated 
amplifiers and/or preamplifiers that operate on the 
RC-5 standard and you need to make each 
component unique w.r.t. remote control operation – 
up to 4 components. Before making the following 
change, you should have a basic understanding 
how to program a universal remote control. The 
following example shows how to change the IR 
codes that the MOON 850P will recognize:
