reMoVal
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.

iMportant:
Contrary to popular belief, wrapping the headset cords around the headband is not
a proper storage method. In fact, by doing so you risk damaging the com cable, splitter, or battery
box. Instead, loosely loop the headset cord in your hand and place the cable in the headset bag,
next to the headset.
general cleaning
To clean the Denali headset, earseals, or headpad, dampen a non-abrasive cloth with water and mild
soap. After cleaning, wipe dry with a soft cloth. Note: do not allow any water to seep into the ear dome.
iMportant:
Do not immerse the headset in water. Never use bleach on ear seals, headpad, or
any other part of the Denali headset.
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.

installation
Lay 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.
