Contact your installing agency for any required changes. 3.2.1 Pairing Process The wiJAC2-002 Wireless Intercom System consists of one JB69 Intercom Adapter, and one factory-paired JB60 Headset Adapter. If either the JB60 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 JB60/JB69 pairing process is described in the following steps: 1. Turn off the JB69 and previously paired JB60. 2. Turn on the JB69. The JB69 enters the standby mode (Power Annunciator blinks in sets of two or three flashes). If the Power Annunciator stays on continuously, the JB60 is still powered on and connected to the JB69. Turn off the JB60. 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 JB60. 4. Turn on the JB60 to be paired with the JB69. The JB60 enters the standby mode (Power Annunciator blinks in sets of two or three flashes). 5. On the JB60, 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 JB60 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 JB60 and JB69 indicate they have completed the pairing process when the Power Annunciators are on continuously.

Operating Manual Rev A Page 14 4 wiJAC™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 JB60-002 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 JB60-002 Headset Adapter in high-noise environments, adjust the VOX control fully clockwise. To communicate, press and hold the JB60-002 Headset Adapter's ICS PTT button and speak in to the headset's microphone. 4.1.4 Live Speaking Operation To use the JB60-002 Headset Adapter so that the microphone audio is always turned on, adjust the VOX control fully counterclockwise. 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 JB60- 002 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 JB60-002 Headset Adapter and the JB69-002 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 JB60-002 Headset Adapter and the JB69-002 Intercom Adapter and connect the headset directly to the audio panel.

Operating Manual Rev A Page 15 If another aircraft system is experiencing a fault, turn off and remove the JB60-002 Headset Adapter and the JB69-002 Intercom Adapter and connect the headset directly to the audio panel. Do not use the JB60-002 Headset Adapter and the JB69-002 Intercom Adapter if they appear to be the cause of the fault. 4.1.8 Battery Life The operating duration of the wiJAC2-002 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): Minimising 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 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. 5 Compliance Statements 5.1 FCC compliance statement This device complies with Part ·15 of the FCC Rules for only portable part.
