Pairing Process
The wiJAC2-D01 Wireless Intercom System consists of one JB69 Intercom Adapter, and one factory-paired JB68 Headset Adapter.

If either the JB68 or JB69 has been replaced, it will be necessary to re-pair the units. This may also be necessary if either of the units has undergone maintenance. To locate the pair switch, the battery cover must be removed from the unit. When the battery cover is removed, the pair switch (P) can be seen on the lower edge of the compartment.

The JB68/JB69 pairing process is described in the following steps:

1.  Turn off the JB69 and previously paired JB68.
2.  Turn on the JB69. The JB69 enters standby mode (Power Annunciator blinks in sets of two or three flashes). If the Power Annunciator stays on continuously, the JB68 is still powered on and connected to the JB69. Turn off the JB68.
3. On the JB69, press and hold the Pair Switch (4 seconds) until the Power and Low Battery Annunciators start flashing rapidly (10 flashes /second). Release the Pair switch. The JB69 enters the pairing mode (Power Annunciator is flashing at a medium rate (5 flashes /second) and can now be paired with the JB68.
4.  Turn on the JB68 to be paired with the JB69. The JB68 enters the standby mode (Power Annunciator blinks in sets of two or three flashes).
5.  On the JB68, press and hold the Pair Switch (4 seconds) until the Power and Low Battery Annunciators starts flashing rapidly (10 flashes /second). Release the Pair switch. The JB68 enters the pairing mode (Power Annunciator is now flashing at a medium rate (5 flashes /second) and will complete the pairing process automatically with the JB69. The JB68 and JB69 indicate they have completed the pairing process when the Power Annunciators are on continuously.

wiJAC™System Operation

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.

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.

VOX Speaking Operation
To use the JB68-001 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.

TX PTT or ICS PTT Speaking Operation
To use the JB68-001 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 JB68-001 Headset Adapter’s ICS or TX PTT button and speak in to the headset’s microphone.

Live Speaking Operation
To use the JB68-001 Headset Adapter so that the microphone audio is always turned on, adjust the VOX control fully counter-clockwise.

Low Battery Warning
When the unit’s battery charge is low, the LOW BATT annunciator will triple flash every 1.5 seconds. When the JB68-001 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.

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.

Loss of Audio
If there is no audio heard in the headset, check the PWR ON annunciator on the JB68-001 Headset Adapter and the JB69-001 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 JB68-001 Headset Adapter and the JB69-001 Intercom Adapter and connect the headset directly to the audio panel. If another aircraft system is experiencing a fault, turn off and remove the JB68-001 Headset Adapter and the JB69-001 Intercom Adapter and connect the headset directly to the audio panel. Do not use the JB68-001 Headset Adapter and the JB69-001 Intercom Adapter if they appear to be the cause of the fault.

Battery Life
The operating duration of the wiJAC-D01 system with 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. This will increase the battery life.

• Obstacles between the Headset Adapter and Intercom Adapter (VOL):
  Minimizing 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.

• The charge capacity of the batteries installed:
  The higher the capacity of the batteries, typically specified as 2000 to 2400 mAh (milliamp-hours), the longer the battery life.

• The type of batteries installed and the operating temperature:
  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.
