Fitting Instructions

Properly fitting Flightcom's E-13 ANR headset to each user's head is crucial to proper

performance. The headpad should fit comfortably on top of the head without a gap

or space between the head and headpad. The headset should be centered on the

head and the ear seals should comfortably cover the ears without being placed too

far forward on the jawbone or face.

• The mic boom may be worn on the left or right side of the head.

When switching between right and left dress, rotate the mic

boom in an upward direction as shown in the diagram.

Rotating the mic boom in the wrong direction may damage

the boom or wiring.

• The mic should be no more than 1/8” from mouth to ensure

clarity and peak performance of the noise canceling mic.

• To increase the size of the headset, slide the domes in a

downward direction. To decrease the size of the headset,

slide the domes in an upward direction.

• Volume control is provided for each ear dome.

Installation

• Insert the headset plug into your aircraft comm panel jack.

• Volume controls are located on each ear dome. Adjust to the desired volume level

on each dome. Note: the ear dome volume control does not affect the volume of

auxiliary listening or cellphone devices.

•Reduce volume on aircraft interphone system before engaging the ANR circuit.

Aircraft interphone volume can be adjusted to a comfortable level after the ANR

circuit has been activated.

Battery Box

The battery box uses two AA batteries to supply power to the headset's ANR circuit.

The battery box also contains additional ports for cellphone and auxiliary listening

devices.

Power On

To turn the ANR power on, depress the “power” button located on the top of the

battery box for two to three seconds. The ANR power will be active immediately,

while simultaneously checking the battery voltage. The battery check first illuminates

the bottom yellow LED and then gradually builds through the green LEDs. The

number of green LEDs lit will be proportionate to the remaining battery life. Four

LED lights indicate full battery voltage capacity. As the battery voltage decreases,

so does the number of LEDs lit. If the yellow LED is continuously illuminated, the

batteries will need to be replaced. If the batteries are not replaced, the unit will

automatically shut off when voltage has dropped below 1.2V.

Sure Power System™(SPS)

To conserve battery life, the E-13 ANR will automatically shut off the system power if

no audio signal is sensed by the headset for a period of 15 minutes or the headset

is stored in a quiet location for more than 15 minutes. To turn the system power back

on, depress the “power” button located on the top of the battery box for two to three

seconds after which ANR power will be turned on, accompanied by a simultaneous

battery check.

DIP Switch

The battery box DIP switches enable or

disable the following features:

Position 1: AUX Enable

Position 2: CELL Enable

Position 3: AUX Mute on CELL enable

Position 4: Auto Power Off (Sure Power System)

All battery box features are enabled when you receive the headset from Flightcom.

To disable any of the factory default settings, you will need to access the DIP switches,

located in the battery box.

To access the DIP switches, open the battery compartment door by pushing down on

the battery release located next to the belt clip. While pushing down on the battery

release, simultaneously slide the unit's battery compartment door toward you.

Remove the AA batteries and set aside. A descriptive DIP switch label is visible

once the batteries have been removed.

Using a small screwdriver or slender tool, gently pull the edge of the label toward

you until you can see the DIP switches. To enable the feature, using your tool, push

the switch into the “up” position. Push the switch in the “down” position to disable

the feature. Once you have completed enabling or disabling the feature, push the

label back into its original position and place the AA batteries in the box. Slide the

unit's door away from you until the door snaps into place.

LED Light

A NVIS friendly, dome mounted Pelican light is provided with your headset. Please

see the enclosed Pelican user manual for operating, maintenance and warranty

instructions.

Troubleshooting

Audio Feedback

• Be sure to maintain good ear seal fit against the head on both sides.

• The electronics and acoustical cavity of the ear cup are tuned to the characteristics

of the ear seals and we recommend that you only use Flightcom replacement

parts when performing hygiene maintenance. Installing incorrect ear seals may

result in improper fit and potentially poor ANR performance.

Intercom volume too loud (or soft) in one ear dome

• Adjust volume knob on each ear dome to achieve comfortable volume balance.

Caution: Inside each ear cup of your headset, you will notice an oval fabric piece.

This is intended to prevent debris from entering the speaker element and to help

ensure proper headset performance. Do not operate the ANR function without these

fabric pieces in place.

Power Off

To turn the ANR power off, depress the “power” button located on the top of the battery

box for two to three seconds. Three quick flashes of the yellow LED will illuminate until the

power is shut off. Once the ANR power is off, the unit will continue to monitor for low battery

voltage and will illuminate the yellow LED if the battery voltage falls below 1.6 volts.

Replacing the Batteries

To install or replace the AA batteries, open the battery box door by pushing down on the

battery release, located next to the belt clip. While pushing down on the battery release,

simultaneously slide the battery compartment door toward you. The compartment door

stops halfway and is not intended to be removed. Do not attempt to remove the door

completely from the unit. Place the AA batteries in the box and slide the unit's door away

from you until the door snaps into place.

Battery life is dependent on the ambient noise in the aircraft, but it should provide an

average of 50 hours continuous use for standard alkaline-zinc batteries.

Caution: Leaving the batteries installed in the battery box when the headset is not in

use for extended periods may result in battery leakage and non-warranty damage to the

headset. Flightcom suggests using only high quality batteries for longer life and reduced

risk of leakage.

Auxiliary-In Audio Jack

The full stereo auxiliary-in audio jack is enabled when ANR power is activated. Follow

“Power On/Power Off” instructions in this manual to turn on system power.

An auxiliary audio jack interface cable is provided with your headset. Plug the cable into

the “AUX” battery box jack and connect the plug to your playback device. Please note

the volume control on the headset does not affect any auxiliary device. Volume must be

set to the appropriate level on the device.

Cellphone Interface Jack

The cellphone interface jack is enabled when the system power is activated. Follow

“Power On/Power Off” instructions in this manual to turn on system power.

A 6' standard 2.5 mm, 3-conductor audio cable is provided with your headset. Please

note that if your cellphone is not equipped with a standard 2.5 mm, 3-conductor headset

jack, you will need to purchase an adapter. You may need to check with the original

cellphone manufacturer or wireless system provider for the appropriate adapter.

To activate your cellphone, plug the cable into the “CELL” battery box jack and plug the

other end of the cable into the headset jack on your cellphone. Please note the volume

control on the headset does not affect the cellphone. Volume must be set to the appropriate

level on the device.
