Important Note
This adapter converts the headset's audio and microphone connection for use with a U-174 helicopter jack. When converting from an aircraft-powered LEMO connection, aircraft power is not supplied through the U-174 plug. Headsets requiring power for active noise reduction or other electronic functions may therefore need to operate from their batteries.
