The 990's remote includes discrete "on" and "off" commands (something that Outlaw started doing with the Model 950 due to numerous requests from Model 1050 owners) to make remote macros easier. That way, folks with universal remotes that support macros can set up one macro to turn the system on (turn on TV, cable box, processor, and so forth) and another macro to turn everything off. The "Power" button is the "off" command (but, as cappra points out, the remote needs to be set to the "TNR" device in order to send commands to the 990). Any of the input buttons will turn the 990 on and set it to that input (again, assuming the remote is set to the "TNR" device at the time).
