NOTES:
THESE INPUTS/OUTPUTS ARE DESIGNED FOR A STANDALONE SYSTEM AND SHOULD NOT BE CONNECTED WHEN INTEGRATING THE RADIO WITH AN AUDIO PANEL.
MOST AUDIO PANELS WILL HAVE DEDICATED CONNECTIONS FOR THESE FEATURES WHICH SHOULD BE USED INSTEAD.
THE 500 OHM AUDIO OUTPUTS ARE BALANCED AND THE PHONE GND MUST BE CONNECTED. IF THE AUDIO PANEL DOES NOT HAVE AN AUDIO LO IT SHOULD BE
CONNECTED TO A GROUND LUG AT THE AUDIO PANEL.
SCREENED CABLE TO MIL 22750 OR 27500 AND THE SCREEN SHOULD ONLY BE EARTHED AT THE AUDIO PANEL END.
