INTERCOM-ONLY HEADSETS
The Intercom-Only Headsets receive both intercom and radio communications at all times,
but are
NOT
radio-transmit capable. Intercom-Only Headsets are typically used at the
jumpseat positions, due to the high ambient noise level at these locations (engine noise, etc.).
There are 4 models of Intercom-Only Headsets: the UH-20, the FH-20, the UH-40 and the
FH-40.
•
The UH-20 and the FH-20 have a
BLACK PTT
button on the ear dome. Press
and hold this black PTT to speak on the intercom.
•
The UH-40 and the FH-40 have a
YELLOW PTT
on the ear dome. Press and
release the yellow PTT to turn the microphone on. Press and release the yellow
PTT again to turn the microphone off.
