3.3.3 Turn On Adapters and Verify Connection
On the JB66 Headset Adapters, turn the VOL knob fully counterclockwise to minimum. Turn on the JB66 Headset
Adapters and the JB67 Intercom Adapter. On both units the PWR ON and LOW BATT annunciators will illuminate for
two seconds.
• When a unit is turned on, the PWR ON annunciator will illuminate for 2 seconds, and the unit will start to search
for units it is paired with.
• While the unit is searching for its paired units, the PWR ON annunciators will triple-flash every 1.5 seconds.
• When the unit is connecting to its paired unit, the PWR ON annunciators will double-flash every 1.5 s until
connection is established.
• After connection, the PWR ON annunciator will illuminate steady green until the unit is turned off.
3.3.4 Verify Audio Operation
Set the aircraft audio system's VOX mode to live or key the aircraft audio system's ICS PTT for the headset
connection used by the JB67 Intercom Adapter.
Adjust the JB66 Headset Adapter's VOX control to fully counter-clockwise, then slightly clockwise to move it out of
detent position. Adjust the VOL control to achieve a comfortable listening level. Confirm that the microphone audio is
live - all microphone audio is heard in the phones. Confirm that the audio level increases as the VOL control is rotated
clockwise and decreases as the VOL control is rotated counterclockwise.
Adjust the Headset Adapter's VOX control to fully clockwise and confirm that the microphone audio is off.
Press the Headset Adapter's ICS PTT button and confirm that microphone audio is heard in the phones.
Adjust the Headset Adapter's VOX control for a comfortable speaking level and return the aircraft audio system's
controls to its previous settings.
