provided by two switches.

on.

headset.

the XMIT SELECT switch is set to.

iii. "BOTH" position permits you to hear both the
aircraft radio(s) and the FM radio at the same
time.
4. The AUXliary audio source is selected by the AUX/OFF
switch. In the "AUX" position, you can hear it, and in the
"OFF" position you cannot.
5. Receive Volume Controls (REC VOL) are general volume
controls, meant to provide overall listening level for all
three radios simultaneously - A/C, FM, and AUX. Finite
volume adjustments of any individual radio should be done by
altering the radio volume control at the radio itself.
