wing should be facing downwards, while the primary but- ton should be on the left side of the throat and the acoustic coil or 3.5mm module attachment should be on right side. The optimal position for a throat mic is about 1-1.5” to the side of the voice box where the Stealth is positioned. The throat mic wing shape was designed for aerodynamic applications so that there would not be pressure applied to the neck under high wind situations. Ergonomics are comfortable and intuitive to use. NOTE: The transponders should rest comfortably on the neck and be in contact with your neck at all times. They should not be too tight. The adjustable straps have flex in order for to maintain the Stealth in position. Dot not over tighten the straps. For users with no prior experience with throat mics, please keep in mind the sound quality will never be as clear as a standard headset. 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. The audio quality is similar to a person with a cold, hence the “muffled” sound that is commonly associated with throat mics. The Stealth benefits from a vast improvement of sound quality through our in-house advancement. IMPORTANT: DO NOT WEAR 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 1 to 1.5 in.

When using a headset, the device uses the primary mic to compare to secondary mic inputs and processes accordingly. When the throat mic is not worn, the secondary mic provide slight voice inputs because no audio is picked up from the throat mic. However, once the throat mic is activated, the audio will perform back to normal.

and ready for use.When charging is needed, connect the included USB cable to the micro-USB port covered by the Primary Button Ring. To access the charging port, remove the Primary Button Ring by turning it counter-clockwise. A full charge takes about 90 minutes to complete and a red LED will remain lit until it is fully charged. Please note to charge with a computer USB port only. Fast chargers (>500mA) may damage the Stealth’s charging mechanism. To avoid damage to the battery, refrain from draining the battery completely and leaving it without charge for an extended amount of time. CHARGING 100% CHARGED C H A R G I N G

• The accoustic coil module • The 3.5mm recess/thin audio connector module. To use the Stealth with helmet speakers or earbuds, please connect the 3.5mm recess/thin audio connector to the throat mic. Each module can be switched and replaced as follow: To properly attach either module, it needs to be turned clockwise and tightened firmly until the IASUS logo is horizontal and right side up. This position ensures proper alignment with the electrical contacts. It should be tightened to the point where it will not turn anymore in order for the silicon ring to maintain a waterproof seal. NOTE: When connecting helmet speakers or earbuds to the iASUS helmet speaker’s 3.5mm jack module, be sure to insert the plug all the way into the module until a click is felt to confirm a waterproof seal has been estab- lished. 3 • Turn clockwise to install the new module and tighten firmly. 1 • Turn counter-clockwise to unscrew the module 2 • Remove the currently installed module I N T E R C H A N G E A B L E M O D U L E S

E L A S T I C W R A P F O R A C O U S T I C C O I L M A G N E T I C B R E A K A W AY C L A S P The Stealth neck strap is equipped with a magnetic breakaway clasp, designed for emergency situations when a rapid removal of the headset is required. This is done by pulling on either strap away from the other to disengage. Under normal usage, always separate the top clasp from the base clasp with a twisting motion – left hand pushing down and right hand twisting up. Only a very light force is required. Disengaging the clasps any other way during normal every day usage is unnecessary and not recommended.

ble Primary Button Caps. The purpose of these two caps is to alter the visibility of the indicator LED. The regular cap allows the LED to shine through while the opaque cap blocks it. You may wish to swap in the appropriate cap depending on your use of the Stealth. To switch caps, turn the Primary Button Ring counter-clockwise, replace the cap, and tighten the ring.

Find “STEALTH” in the list of available devices in the Bluetooth menu of the device you are pairing. The STEALTH uses standard Bluetooth 5.0 protocols. When paired with newer devices, there is no need to enter a passcode. For older Bluetooth equipped devices, enter the code “0000” A list of supported protocols can be references in the Speci- fications section.

Find “STEALTH” in the list of available devices in the Bluetooth menu in the device you are pairing. Pairing the second device will disconnect STEALTH from the first device - this is normal. Go to your first device’s Bluetooth settings and manually reconnect to STEALTH.

The STEALTH is carefully designed and built on 3 main user actions to achieve a minimalistic appearance. • The Primary Button, located on the left side of the neck, has a silicone cap that doubles as an LED indicator when activated • A pair of + and - control buttons for volume control and skipping tracks located on the bottom of the wing All controls were designed for glove application.

O N M U S I C M O D E & P H O N E M O D E During Music Mode (music playback), STEALTH’s volume level is adjusted independently of the phone’s Bluetooth playback volume. During a phone call, STEALTH’s volume and the phone’s volume are linked, following standard Bluetooth protocol. TIP: If you experience low volume on Music Mode, be sure the volume is turned up on your phone as well as on STEALTH. Example: When adjusting STEALTH’s volume in Music Mode, the phone’s Bluetooth volume is not affected. However, in Phone Mode, adjusting STEALTH’s volume during a call affects the phone’s Bluetooth volume as well.

QUESTION SOLUTION I paired the Stealth to my PC and when Windows tried to automatically install the drivers for the Stealth, it comes back with multiple “Bluetooth Peripheral Device – No Driver Found” errors. Where can I find the drivers? I do not get any sound with my Acoustic Coil or Helmet Speakers. My voice sounds distorted and muffled on the other party’s device. The volume coming out of the helmet speakers or earbuds are too soft even when the volume level on the Stealth is at the loudest. The volume coming out of the Acoustic Coil sounds very low. How can I clean the necks trap? This means Windows was not able to find any Bluetooth drivers for your PC hardware. Please ensure you have your computer manufacturer’s Bluetooth driver installed and try to pair the Stealth again. It should automatically install all Bluetooth related functionalities of the Stealth upon pairing. • Please ensure the selected module is screwed on tightly. Check the outer edge of the module is lined up with its base and the IASUS logo is perfectly horizontal. This position ensure a proper connection with the headset. Try speaking in a low volume and in a soft, calm and clear manner. Loud volume will overwhelm the sensitive transponder microphone resulting in clipping of audio levels. Turn up the volume on your device during music playback. In Music Mode, the phone’s Bluetooth volume level is independent of the Stealth’s. Use an ear plug for your other ear when using Stealth in loud environments. In this scenario, your other ear becomes the dominant ear, making it difficult to get the audio from the Acoustic Coil. The neck strap can be taken off of the Stealth headset to wash by hand or put into a washer and dryer. • If using the 3.5mm jack module, make sure the 3.5mm jack plug of the speakers or earbuds is completely inserted. Use only helmet speakers or earbuds equipped with a slim 3.5mm plug.
