Interchangeable Audio Module
The Stealth can operate with our acoustic coil or helmet speakers which use the 3.5mm
recess/thin audio connector. This is done by installing the appropriate audio module.
To properly attach these modules, they need to be turned clockwise and tightened very
firmly until the IASUS logo is horizontal and right side up. This position ensures proper
alignment with the contacts. Note: It should be tightened to the point where it will not
turn anymore in order for the silicon ring to maintain a waterproof seal.
When connecting the helmet speaker’s 3.5mm jack, be sure to insert the plug all the
way into the jack until a click is felt to ensure the waterproof seal has been established.
Magnetic Breakaway Clasp
The Stealth neck strap is equipped with a magnetic breakaway clasp. It is designed for
emergency situations where a rapid release of the headset is required by pulling on
either strap away from the other to disengage.
Under normal usage, separate the top clasp from the base clasp with a light twisting
motion – Only a very light force is required. Disengaging the clasps any other way during
normal every day usage is unnecessary and not recommended.
Throat Mic Optimization
For users with no prior experience with throat mics, please keep in mind the sound
quality will never be as clear as a standard phone. This is because the audio is created
from vibrations of the larynx through the body of the throat. Since air is not the medium,
nasal sounds will be absent. Basically, the audio quality is similar to a person with a cold,
hence the “muffled” sound that is commonly associated with throat mics.
That being said, the Stealth benefits from a vast improvement of sound quality through
our in-house advancement.
It is important to note to NOT HAVE THE THROAT MIC AND STRAP TOO TIGHT AROUND
THE NECK. When worn properly, the neck strap should rest on the back of the neck and
only very little pressure should be felt.
