10. Mission-Critical Communications Soundscape ComTac™ VIII features soundscape to help promote speech intelligibility in noise. Soundscape enables automatic changes to product settings dependent on the user environment. When Soundscape is set to On, the following functions are activated: • Increased Radio volume in high continuous noise (when radio volume is set to auto). • Increased voice prompt volume in high continuous noise. • Reduced radio static/hiss between transmissions. Fail Safe External communications and environmental listening functions are independent for Rx/Tx fail safe; in the event of electronic failure or battery depletion, external device communications will continue to function Communications play a vital role in modern tactical operations. The ability to communicate is critical to react, coordinate and respond effectively. 10

12. Ballistic Helmet Integration Accessory Rail Connectors (ARC) 3M General Service Respirator Platform Microphone The ear cup has been designed to help provide the maximum amount of attenuation while limiting the thickness of the cup for compatibility with mid and low-cut ballistic helmets. • Easy donning/doffing • In the “open” position, the operator can easily don/doff the helmet/ headset and adjust for proper fit. • Heat relief • The ability to have an “open” position of the headset allows the user to ventilate in high-heat environments but can still monitor communications in low-noise environments. The 3M General Service Respirator Platform Microphone (7000556) is designed for use with the following 3M Defence and Public Safety Respirators only; - • General Service Respirator - (GSR) • General Service Respirator – Evolution – (GSRe) • General Service Respirator – Evolution Specialist – (GSReS) • First Responder Respirator – (FRR) NOTE: Subject to Export Control restrictions 12

7. Ambient listening Off - For maximum sound reduction when in high noise and monitoring a radio or NIB. Conversation - Intended to closely approximate open ear listening and sound localization. Ideal setting for extended use when other modes are not needed. Comfort - For comfort in a noisy environment. Intended for use in periods of loud noise (tactical vehicle, air transport) where environmental listening is not prioritized over communications.

8. Effective hearing protection without compromising communication Hearing Protection In critical situations, noise levels can be so high that they cause immediate, permanent damage to your hearing if proper protection is not worn. The 3M™ PELTOR™ ComTac™ VIII helps provide hearing protection and can also be worn in combination with passive earplugs, or 3M™ PELTOR™ Tactical electronic earplugs (TEP), to help provide additional protection if required. Dual Hearing Protection In military environments, high levels of steady state and impulse noise are common. When operating in high levels of noise, dual hearing protection may be required not only for protection but also to maintain clear communications. EarPlug Mode ComTac™ VIII offers “Ear Plug mode.” In ear plug mode, it is possible to use the headset in combination with passive ear plugs while maintaining a degree of auditory situational awareness. Environmental listening, radio volume and voice prompts is boosted to help compensate for the additional attenuation provided by the ear plug. 8

3. 25 Years of Changing the Game The first ComTac ™ headset was introduced in 1998. Designed to help give operators a tactical edge, it quickly became a trusted solution for military and law enforcement operations worldwide. With ComTac ™ VIII we bring forward the next generation communication and hearing protection platform.

Updated Earcup Designed to help provide the maximum amount of attenuation while limiting the thickness of the cup . A deeper cup with more space for ears, to help improve long term comfort, especially when worn in combination with ear plugs.  Soundscaping Automatic soundscaping to help promote speech intelligibility in noise. 5

6. Environmental Listening for Auditory Situational Awareness  Hearing as a sensor A Warfighters’ hearing is arguably their most sophisticated battlefield sensor. We can process large amounts of auditory information that can significantly affect lethality and survivability. Environmental Listening Feature The environmental listening feature, also known as “talk- through” is a means of allowing safe audio sounds to bypass the individual hearing protection electronically while still helping protect against harmful noises. A microphone receives the sounds outside of the headset and transmits them to a speaker inside of the headset. The level-dependent digital audio circuit senses noise levels above the desired threshold and compresses them to a safe decibel level or amplifies weak sounds to an audible level. Mission Audio Profiles (MAP) 3M™ PELTOR™ ComTac™ VIII Headset offers a way to adjust the auditory settings of your headset for your mission. Traditionally, a headset has a set frequency response, and the operator can only increase or decrease the volume. The MAP function provides new advanced ambient/environmental listening modes that allow access to a variety of gain settings, but with frequency shaping, to enhance auditory performance in five conditions. The MAP Profiles have been designed with a variety of combat and combat support operations in mind. Observation - For maximum auditory awareness and sound detection in a quiet environment. To be used when the user is still and in a quiet environment (overwatch, hide spot, stop to listen, etc). Patrolling - For high situational awareness when walking in a low noise environment. High volume with reduced high frequencies to limit sounds such as footsteps on gravel, grass moving under feet, or equipment moving on body. Mission Audio Profile 1 Mission Audio Profile 2 6

17. 17 Laboratory Noise Attenuation. Standard EN 352-1:2020 Impulsive Peak Insertion Loss (IPIL): ANSI/ASA S12.42-2010 (R2020) 3M strongly recommends personal fit testing of hearing protectors. Research suggests that users may receive less noise reduction than indicated by the attenuation label value(s) on the packaging due to variation in fit, fitting skill, and motivation of the user. Refer to applicable regulations and guidance on how to adjust attenuation label value(s). In the absence of applicable regulations, it is recommended that the attenuation label value(s) be reduced to better estimate typical protection. The attenuation rating (SNR) was obtained with the device powered off.
