turned on, adjust the VOX control fully CCW.
6.6
Low Battery
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 every three minutes. When the
battery charge is low replace or recharge the batteries.
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 triple flash.

Battery Life
The duration the wiJAC-001 system will operate on fully charged batteries,
before battery replacement is required, depends on the following factors:
Distance between Headset Adapter and Intercom Adapter:
The closer together the units are the lower the radio frequency (RF)
power required for connection and will increase the battery life.
Obstacles between the Headset Adapter and Intercom Adapter:
Reducing the aircraft metal structures, human bodies, cargo and other
obstacles between the units will reduce the RF power needed for
connection and increase the battery life.
Charge capacity of the batteries installed:
The higher the capacity of the batteries, typically specified as 500 to
1000 mAh (milliamp-hours), the longer the battery life.
The type and temperature of the batteries installed:
During low temperature operation, rechargeable batteries will lose
capacity. When operating in low temperatures use alkaline batteries for
a longer battery life.
The phones volume level and usage rate:
The lower the volume level and the less often audio is output to the
phones the longer the battery life.

Operation during Charging
The units will operate while the Charging Port is connected to a USB power
source. Additional noise may be heard on the audio system while the
Charging Port is connected to a USB power source.
