Microphone And Boom Adjustments; Installation; Care And Maintenance - Flightcom Denali D50ANR Operation Manual

MICROPHONe AND BOOM ADjUSTMeNTS

• Adjust the mic boom for proper fit and comfort. Place the microphone no
more than 1/8" from lips, at the corner of the mouth. This is critical to the
performance of the noise-canceling electret microphone.
IMPORTANT: All Denali mic booms are shipped from the factory for wearing
on the left side of the head only. Because the domes are canted to match the
angle of the ears, the boom can ONLY be worn on the left side.
CAUTION: Rotating the boom beyond the "stop" will cause non-warranty damage
to the boom

INSTAllATION

• Insert the larger headset plug into the jack marked "headphone" or "phone" (on your aircraft
com panel, intercom or radio).
• Insert the smaller headset plug into the jack marked "microphone" or "mic."
• Set the stereo/mono switch on the cable splitter box to the "M" position. If connecting to a
stereo intercom, set the switch to the "S" position.
• If you are not sure about the type of intercom in the aircraft, test the headset by selecting the
"S" position and talking into the headset. If you hear sidetone out of one ear only, you have a
mono intercom. Move the switch to "M."
• for the ANR model: The stereo/mono switch is located on the back of the in-line battery box,
near the clip.
• Adjust the headband sliders for proper fit and comfort, making sure the boom is being worn on
the left side of the head.
• Individual volume controls are located on the front of each eardome to reduce or adjust the
level of audio in each headset ear cup.
• for the ANR model: Once the 9-volt battery is installed, turn the ANR power to the ON
position, indicated with the symbol "|". The OFF position is indicated with an "o". A blinking
green LED indicates the active noise cancellation circuit is ON. A blinking red LED indicates
low battery life. (For proper battery installation, see the diagram in the Care and Maintenance
section of this guide.)
If the aircraft does not have a built-in push-to-talk (PTT) switch, a portable PTT switch must be
installed in order to use the radio.
An avionics technician should optimize the master gain control located in the aircraft radio
whenever adding a new model microphone to the system.
Sure Power System(SPS):To conserve battery life, ANR models will automatically shut off
the ANR circuit if no audio is sensed by the headset for a period of 28 minutes. Full passive
performance is maintained. ANR operation is reactivated by turning the ANR power switch to
the OFF position and back to the ON position, indicated with the symbol "|".

CARe AND MAINTeNANCe

geNeRAl CARe
As with most electronic equipment, it's important to protect your Denali headset from exposure to the
elements. Do not leave the headset on the seat of a plane or car, or in intense, direct sunlight exceeding
156° F. Do not leave the headset out in the rain or in freezing temperatures. Return the headset to its
carrying case and store in a cool, dry area.
