wiJAC2™System Operation
4.1
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.
4.1.1
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.
4.1.2
VOX Speaking Operation
To use the JB66 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.
4.1.3
ICS PTT Speaking Operation
To use the JB66 Headset Adapter in high-noise environments, adjust the VOX control fully counter-clockwise until the
knob clicks into detent position. To communicate, press and hold the JB66 Headset Adapter's ICS PTT button and
speak in to the headset's microphone.
4.1.4
Live Speaking Operation
To use the JB66 Headset Adapter so that the microphone audio is always turned on, adjust the VOX control fully
counter-clockwise.
4.1.5
Low Battery Warning
When the unit's battery charge is low, the LOW BATT annunciator will triple flash every 1.5 seconds. When the JB66
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 when 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.
4.1.6
Operation during Charging
The units will still operate while the Charging Port is connected to a USB power source, but the batteries will charge at
a slower rate. Additional noise may be heard on the audio system while the Charging Port is connected to a USB
power source.
4.1.7
Loss of Audio
If there is no audio heard in the headset, check the PWR ON annunciator on the JB66 Headset Adapter and the JB67
Intercom Adapter. If a unit is off, turn it on and verify connection and operation.
If the battery charge is low, replace or recharge the batteries or connect the headset directly to the aircraft audio
system.
If audio is unintelligible, turn off and remove the JB66 Headset Adapter and the JB67 Intercom Adapter and connect
the headset directly to the audio panel.
