2.1.1.3  

VOL

 (Phones Volume Control) 

WARNING

: Loud noise can cause hearing damage. Before using the headset, set the volume to 

minimum, and then slowly increase it to a comfortable listening level. 

The volume control is a rotary knob marked VOL (volume) located on the top left of the JB66 Headset Adapter. To 

reduce the volume of the audio heard in the headset rotate the VOL knob counterclockwise. To increase the volume 

of the audio heard in the headset rotate the VOL knob clockwise. 

2.1.1.4  

TX

 

PTT

 (Push To Talk) Button  

The Transmit Push To Talk button is a square push button switch marked TX PTT on the lower front of the JB66 

Headset Adapter. When the TX PTT button is pressed and held, microphone audio is routed to the Intercom Adapter 

and the TX Key output is also activated. 

This is the user’s Transmit ‘Push To Talk’ (TX PTT) button. While this button is pressed, the 

wiJAC2™

 system will 

allow the user to transmit on the transceiver selected on the audio controller.  If the TX PTT button is used, the VOX 

threshold will be overridden (see section 2.1.1.2 above). 

While the TX PTT button is pressed, all other linked JB66 Headset Adapters are prevented from transmitting. 

2.1.1.5  

ICS

 

PTT

 (Push To Talk) Button  

The intercom Push To Talk button is a hexagonal push button switch marked ICS PTT located on the upper front of 

the JB66 Headset Adapter. When the ICS PTT button is pressed and held, the VOX threshold is overridden, 

microphone audio is routed to the paired Intercom Adapter, and the ICS Key output is also activated. 

2.1.2  

JB66 Connectors 

2.1.2.1 

Headset Jack  

The headset jack is a 4-pole TJT-120 jack on the top of the JB66 headset adapter. An appropriate 

mating headset 

connector can be inserted directly into the jack 

(see 

section 3.3.2.1

 for adapter cables).

 

2.1.3  

JB66 Annunciators  

2.1.3.1  

PWR ON

 (Power On)  

The power on (PWR ON) annunciator is a green LED located on the front left of the unit.  

  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. 

2.1.3.2  

LOW BATT

 (Low Battery Warning) 

The low battery (LOW BATT) warning annunciator is a red LED located on the front right of the unit. When the unit is 

turned on, the LOW BATT annunciator will illuminate for 2 seconds. 

When the JB66 battery voltage is low the LOW BATT annunciator will flash once every 1.5 s and output a low battery 

notification (a triple beep) in the headphones once every minute until the battery charge reaches critical voltage level. 

(A similar but higher pitched tone will be heard if the paired JB67 Intercom Adapter battery charge is low.) 

 

Note

:

 JAC recommends that the batteries should be charged or replaced immediately if the LOW BATT 

warning illuminates during use. 

When the unit battery charge is less than or equal to the critical battery voltage, the unit will turn off.
