•Switch 5: Set to A at the factory for operation with new headsets. Set it to B if you are installing a portable cable onto an older, exist- ing Aviation Headset 
that was manufactured before June, 2003.
Note: If you cannot determine the manufacture date of your headset, refer to “Locate the serial number for your product registration card” on page 10.

Set it for stereo (ST) if your aircraft has a stereo intercom.
