Technical information

To Enable Auto Shut Off

The ENABLE position provides automatic shut off of power to the ENC system if the

headset is unplugged or the aircraft audio system power is turned off. To operate

the Auto Shut Off switch remove the battery, and using a small pointed tool gently

move the switch to the desired position. Replace battery (see Fig. 1).

Power Indicator

A bi-color LED, mounted on the top of the battery pack indicates the status of the

battery (see Fig. 2).

When the battery is good and the headset is powered, the LED will blink green

approximately once per second. When the battery is low, the LED will be red until

the battery is fully discharged (see Fig. 2).
