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.
6.4.3
VOX Speaking Operation
To use the JA66 Headset Adapter hands-free, adjust the VOX control so that the
microphone audio is turned on when speaking into the headset's microphone at a
comfortable level, or at a level to keep the ambient noise from turning on the
microphone audio.
6.4.4
TX PTT or ICS PTT Speaking Operation
To use the JA66 Headset Adapter in high-noise environments, adjust the VOX
control fully clockwise. To communicate, press and hold the JA66 Headset
Adapter's ICS or TX PTT button and speak in to the headset's microphone.

Live Speaking Operation
To use the JA66 Headset Adapter so that the microphone audio is always turned
on, adjust the VOX control fully counterclockwise.

Low Battery Warning
When the unit's battery charge is low, the LOW BATT annunciator will triple flash
every 1.5 seconds. When the JA66 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.
6.4.7
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.
