3.10.3  Music Input 
When used as a music input, the front panel jack is treated as Music #1. However, thanks to the function 
controls, it can be distributed to all users, regardless of the intercom mode. A patch cord is available with 
2.5 mm to 3.5 mm (3/32 to 1/8” ) adapter cord (PS Part Number 425-006-2535). 
3.10.4  Smart Function Keys (SFK) 
With Virtual Tech Support, the configuration process is self-directed. Once you’ve set up your system, you 
don’t need to change it again, unless you want to. The unit will always remember your settings.  
SFK annunciations are heard by the pilot and copilot positions only. SFK annunciations will be heard by 
the copilot, even when the audio panel is in pilot isolate mode. These annunciations will be stopped by 
any audio received on the com radio selected for transmit (software level BPBC and above).
