and protect the user's hearing from damage.

IMPORTANT USER INFORMATION

For the best protection, ear cushion sealing ring should seal firmly against head, Anything

that interferes with the seal - such as long hair(pull back to the extent possible), thick or

poorly fitting eyeglass temples, pencils or caps - will lessen the protection.

Earmuffs must be regularly inspected for cracks or worm parts, it may affect the acoustic

performance of the earmuffs. Typical life for foam cushion sealing rings is 12 months.

Clean the exterior of the hearing protector regularly with soap and warm water. Do not

immerse the whole headset in water.

Do not store the hearing protector behind a windshield or at temperatures above 131°F

(55°C).

Certain chemical substances may damage this product. Contact the manufacturer for more

information.

CAUTION

To reduce the risks associated with harmful noise or chemicals:

If instructions are not followed, bodily injury may result or protection may be severely

affected.

When interference increases or the sound level becomes too weak, it is time to change the

batteries.

Do not store the batteries installed. A leaking battery may cause bodily injury or damage to

the hearing protector.

These hearing protectors help reduce exposure to hazardous noise and other loud sounds.

Misuse or failure to wear hearing protectors at all times when you are exposed to noise may

result in hearing loss or injury.

If there is any drainage from your ear or if you have an ear infection, consult with your

physician before wearing hearing protection. Failure to do so may result in hearing loss or

injury.

The EARMOR M32 Mark 3 MilPro is a tactical communication and hearing protection headset designed to safeguard hearing, enhance situational awareness, and facilitate communication in noisy environments. This advanced headset offers multiple functions and levels of environmental listening, making it adaptable to various scenarios. For user convenience, it also features a replaceable bracket designed for helmet rail installation.

Function Description

The primary function of the M32 Mark 3 MilPro is to provide hearing protection by suppressing harmful noise while allowing users to maintain situational awareness and communicate effectively. It achieves this through a combination of passive noise reduction and electronic sound amplification/suppression.

The headset incorporates a "Super fast attack time" of less than 1 ms, which instantly suppresses ambient sound to protect the user's hearing from sudden loud noises. It also features "Clear voice tracking," which seeks out and reduces background/environmental noise to improve speech intelligibility, ensuring clear communication.

For enhanced communication in electromagnetically interfered (EMI) environments, the headset includes an "Increased RF immunity" feature. Its EMI and RFI (Radio Frequency Interference) filter suppresses interference generated by devices or other equipment, allowing the M32 Mark 3 to effectively manage electromagnetic interference signals.

The headset offers several distinct listening modes, selectable via the "+" and "-" buttons:

Quiet Mode: Automatically shields outside sounds in high-noise environments, allowing the user to focus on radio communication.
In-car or Indoor Noisy Environment Mode: Features a long release time to prevent echo damage, suitable for specific indoor or vehicle settings.
Conversation Mode: Restores real environmental sound, completely simulating normal human hearing for natural interaction.
Patrol Mode: Appropriately amplifies ambient sound to enhance perception of the surrounding environment.
Observing Mode: Provides maximum amplification of surrounding environmental sound to heighten hearing acuity and facilitate the detection of subtle sounds.

Usage Features

The M32 Mark 3 MilPro is designed for ease of use and adaptability.

Fitting the Headset:

To wear the headset, users should fully extend the sliders and place the cups over their ears, ensuring the microphones face forward. The headband can then be tightened for a secure fit.

Adjusting Helmet Padding:

For users wearing a helmet, the headset can be adjusted by removing the dome pad from the top of the helmet and replacing it with two oblong pads. These oblong pads create a channel for the headband, ensuring a proper fit with the helmet.

Power and Volume Control:

The headset is powered on or off by pressing and holding the power button for 3 seconds. The same button, along with the "+" and "-" buttons, is used to adjust volume and switch between the different listening modes.

Detachable Microphone:

The external communications boom microphone is detachable and can be assembled for either left or right-handed users, offering flexibility based on preference.

Auto Shut-off:

To conserve battery life, the hearing protector automatically powers down after 4 hours of non-activity, signaled by three beeps. Users can reactivate it by pressing the ON/OFF button.

Battery Installation:

To install batteries, the cover should be twisted counterclockwise to open. After inserting the batteries, the cover is twisted clockwise to close.

M11 Bracket Replacement:

The manual provides detailed instructions for replacing the M11 bracket, which involves several steps:

Separation: This includes removing the microphone plug, detaching rotatable parts, separating the microphone and headphones, uncovering Velcro to access wires connecting the earmuffs, and carefully separating the ear cups from the ear pads. Users are advised to wear gloves during this process to prevent cuts from sharp components.
Replacement: This involves taking out the M11 bracket from the accessories, aligning holes, inserting rotating nails (component E) into the bracket, and then installing the positioning fastener (component D). Attention must be paid to the position of the wire connecting the ear cups on both sides. Finally, the ear pads and ear washers are aligned and pressed firmly onto the ear cups, and the microphone is installed on the desired left or right side.

Maintenance Features

Proper maintenance is crucial for the longevity and performance of the M32 Mark 3 MilPro.

Regular Inspection:

Earmuffs should be regularly inspected for cracks or worn parts, as these can affect acoustic performance. The typical lifespan for foam cushion sealing rings is 12 months, after which they should be replaced.

Cleaning:

The exterior of the hearing protector should be cleaned regularly with soap and warm water. It is important not to immerse the entire headset in water.

Storage:

The hearing protector should not be stored behind a windshield or at temperatures above 131°F (55°C) to prevent damage.

Battery Management:

When interference increases or the sound level becomes too weak, it is an indication that the batteries need to be changed. It is important not to store the hearing protector with installed batteries, as a leaking battery can cause bodily injury or damage to the device.

Chemical Exposure:

Users should be aware that certain chemical substances may damage the product. For more information regarding chemical compatibility, users should contact the manufacturer.

Medical Considerations:

If there is any drainage from the ear or an ear infection, users should consult a physician before wearing hearing protection to avoid potential hearing loss or injury.
