™ Set-up and Connection
6.3.1
Insert Batteries
Ensure the batteries for all units are fully charged and installed in the battery
compartment with the correct polarity, and the battery lid is secured (section 6).
6.3.2
Attach JA66 Headset Adapter and JA67 Intercom Adapter
Insert a headset with a U-174/U or U93A/U type plug into the JA66 Headset
Adapter jack.
Connect the JA67 Intercom Adapter plug to the required
connector using the
appropriate cable (see sections 6.1 and 6.2 for system examples).
6.3.3
Turn On Paired Adapters and Verify Connection
On the JA66 Headset Adapters, turn the VOL knob fully counterclockwise to
minimum. Turn on the JA66 Headset Adapters and the JA67 Intercom Adapter.
On all 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 its paired unit.
•
While the unit is searching for its paired unit the PWR ON annunciator will
triple-flash every 1.5 seconds.
•
When the unit is connecting to its paired unit, the annunciator will double-
flash every 1.5 s until connection is established.
•
After connection, the annunciator will illuminate steady green until the unit is
turned off.

Verify System Audio Operation
For an aircraft system, 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 JA67
Intercom Adapter. For non-aircraft radio, increase the radio volume.
Adjust the JA66 Headset Adapter's VOX control to fully counterclockwise and the
VOL control to achieve a comfortable listening level. Confirm that the microphone
audio is live - all microphone audio is heard in the paired JA66 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 paired JA66 phones. For TX PTT, audio will be heard in the
aircraft audio system or transmitted by the attached radio transceiver.
Adjust the Headset Adapter's VOX control for a comfortable speaking level and
return the audio system's controls to the previous settings.
