Your new Denali ear seals are permanently attached to the hard
plastic backing plate. Do not attempt to remove the ear seal from
the backing plate.
To remove the ear seal assembly, look inside the ear seal opening,
half way down either side of the ear cup. You will notice a small
cut-out just large enough to place your finger tip under the backing
plate. Pull the backing plate (with the ear seal) away from the ear
cup. Note: it will take a bit of force and the ear seal will pop off of
the ear cup.

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.

ay the gasket (for ANR models only) flat on the ear seal backing plate. The gasket must have no
wrinkles. Carefully position the backing plate (with the gasket) on the ear cup and apply even pressure
with your fingers spaced around the circumference of the ear seal/backing plate and then snap on to
the ear cup. Note: the backing plate must not have any space between it and the ear cup.
Your new Denali headpad is permanently attached to the backing plate. Do not remove the headpad
from the backing plate.
To remove the headpad, pull on each side of the headpad and it will snap out of position on the
headset. To install the headpad, line it up to the top of the headset and then snap into position.

Denali headsets accommodate the differences in head shapes and sizes of the pilot population
through angled ear domes, the shape and surface area of the ear seal, low side force and a light-
weight design. When worn properly, you will feel very little pressure on top of the head, which is a
refreshing departure from the traditional fit and feel of an older style aviation headset.
Additionally, personalized fit adjustments can be made in the length of the headband, the rotation
of each ear cup, both side-to-side and up and down, and the placement of the boom and microphone.

Do not store your Denali headset in temperatures that exceed 156°Fahrenheit. Do not
leave it in the sun, or hanging on the yoke of your aircraft, or exposed in conditions where the surface
area of the headset might exceed this high temperature.
Under certain conditions, a mic muff might be necessary. A mic muff is provided for your convenience.
We also recommend that in the interest of hygiene, you replace your ear seals at least annually.
• Hold the Denali headset in front of you. Place the dome that holds the mic boom in your left hand.
• Extend the headband to full extension. When you have reached the
maximum headband extension, the headband slider will stop. Make
sure you have extended the headband equally on both sides.
• Place the headset on your head. If the domes feel as if they’re sitting too
low on your ears, starting on one side of the headset, move the headband
slider to a smaller position, ensuring both sides are adjusted equally.
 While wearing the Denali, you should feel very little pressure
on top of your head. THIS IS NORMA AND OPTIMA .
If you’re an experienced headset wearer, you may have a tendency to reduce
the headband size until you feel a familiar pressure on the top of your head or
at the top of your jawbone. For Denali, this indicates you’ve actually reduced
the size of the headband too much. Extend the headband in a downward
direction, on both sides, until the top of the headset seems to "disappear."
Check for a secure fit by shaking your head from side to side. Denali should
remain firmly in place—without creating undue pressure on the top of the head.

Denali’s ear domes rotate not only in an up and down direction, but also from side-to-side. This allows
for maximum adjustment around the ear and jaw area.
• Once the headset is in place and the headband is
adjusted properly, you may want to individually rotate
the dome and ear cup around each ear, to determine
the most comfortable position.
• If during an extended flight you start to feel a bit of a
pressure point, adjust the ear cup or the length of the
headband to restore comfort. Outward dome rotation
Inward dome rotation
• 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.

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.

box also contains additional ports for cellphone and auxiliary listening devices.

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 ED and then gradually builds
through the green EDs. The number of green EDs lit will be proportionate to the remaining battery
life. Four lit EDs indicate full battery voltage capacity. As the battery voltage decreases, so does
the number of lit EDs. If the yellow ED 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. The ANR function, cell phone and auxillary jacks will no longer work.

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

Once the ANR power is off, the unit will continue to monitor for low battery voltage and will illuminate
the yellow ED if the battery voltage falls below 1.6 volts.

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.
