™System Operation
5.2.1
Overview
When both units are turned on and connected, phones audio from the
aircraft audio system is transmitted from the Intercom Adapter, received by
the Headset Adapter and output on the headset's phones. Microphone audio
from the headset's microphone is transmitted from the Headset Adapter,
received by the Intercom Adapter and output to the aircraft's audio system.
5.2.2
Listening Operation
The Headset Adapter's Phones Volume (VOL) controls the level of audio
heard in the headset's ear phones. As ambient noise levels change, the
volume can be adjusted.
5.2.3
VOX Speaking Operation
To use the JA60 Headset Adapter hands-free, adjust the VOX control so that
the microphone audio is turned on when speaking in to the headset's
microphone at a comfortable level, or at a level to keep the ambient noise
from turning on the microphone audio.
5.2.4
PTT Speaking Operation
To use the JA60 Headset Adapter in high-noise environments, adjust the
VOX control fully clockwise. To communicate, press and hold the JA60
Headset Adapter's PTT button and speak in to the headset's microphone.
5.2.5
Live Speaking Operation
To use the JA60 Headset Adapter so that the microphone audio is always
turned on, adjust the VOX control fully counterclockwise.
5.2.6
Low Battery Warning
When the unit's battery charge is low, the LOW BATT annunciator will triple
flash every 1.5 seconds. When the JA60 Headset Adapter battery charge is
low, a triple-beep will be heard in the headset once every minute.
Note:
JAC recommends that the batteries should be charged or
replaced immediately if the LOW BATT warning illuminates during
use.
When the battery charge level is critical, the unit will turn off. When one unit
is off the other unit will begin searching for its paired unit and its PWR ON
annunciator will flash.
