iMportant user inforMation
Warning: 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.
fitting instructions
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.
personalizeD heaDBanD aDJustMents
• 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.
iMportant: While wearing the Denali, you should feel very little pressure
on top of your head. THIS IS NORMAL AND OPTIMAL.
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.
inDiViDual ear DoMe aDJustMents
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.
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 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 lit LEDs indicate full battery voltage capacity. As the battery voltage decreases, so does
the number of lit LEDs. 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. The ANR function, cell phone and auxillary jacks will no longer work.
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.
sure power system™ (sps)
To conserve battery life, the V90 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 at the factory. To disable any of the factory default settings, 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 a 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 until it snaps into place.
