battery types other than NiMH or NiCad may cause the batteries to
leak or explode and cause damage or injury.

Loss of Audio
If there is no audio heard in the headset, check the PWR ON annunciator on
the JA60 Headset Adapter and the JA61 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 JA60 Headset Adapter and
the JA61 Intercom Adapter and connect the headset directly to the audio
panel.
If another aircraft system is experiencing a fault, turn off and remove the
JA60 Headset Adapter and the JA61 Intercom Adapter and connect the
headset directly to the audio panel. Do not use the JA60 Headset Adapter
and the JA61 Intercom Adapter if they are the cause of the fault.

Batteries
JAC recommends Duracell 800 mAh (or higher) NiMH or Duracell alkaline
batteries for use in the wiJAC
™ system to obtain the typical battery life.
The JA60 and JA61 each require three AAA batteries.
Removal of the batteries WILL NOT change any internal configuration of the
unit.
