Hearing Protection

Fit Checking

Choose smallest size that provides good seal and secure t, but large enough that the outer ange seal ear

canal at ear canal entrance. One quick and easy t check is the pump test. The seal can be tested by gently

pumping the plug in and out of the ear canal, while the rocker switch is in the Closed Mode position. When

a proper acoustic/pneumatic seal is present, the pumping motion will cause the pressure changes in the ear

which the wearer should be able to detect. They will be much less noticeable or totally absent while the rocker

switch is in the Open Mode position. If no difference can be detected between the Open/Closed Modes the plug

is probably not sealing the ear. Additionally, the users voice should sound louder and deeper when they speak

or hum.

The 3M Combat Arms Earplugs - Generation 4.1 are available in three sizes. Consult with your Hearing

Conservation Program Manager, health care provider or the manufacturer for advice on selecting the best earplug

size to properly t your ear canal.

The earplugs contain a housing assembly featuring a rocker switch with a tiny hole and CAE on the lower tab

and 3M logo on the upper tab. When the tab featuring the 3M logo is pressed (see Fig. 1) the device acts as

a conventional earplug providing protection against steady noise arising from aircraft, vehicles, generator and

watercraft, for example. This is called the Closed Mode. Notice that sounds are quieter in this mode. When the tab

featuring the CAE and tiny hole marking is pressed (see Fig. 2) the device allows some sound to pass through,

while still helping protect hearing from impulse noise such as weapons re. This is called the Open Mode. The

Open Mode may assist the user with improved situational awareness.

Step 1. Ensure that the plug labeled with an “L” is used for the Left ear and the plug with an “R” is used

on the Right ear. Ensure the retainer is oriented generally as shown relative to the rocker switch.

Step 2. Insert the plug into the ear canal while pulling the ear outward and upward with the opposite hand.

Ensure the rocker switch is in a vertical position. (see Fig. 3)

Step 3. Use index nger to push and bend the retainer into the concha to help ensure the earplug is seated

securely. (see Fig. 4)

Step 4. If properly inserted, the retainer should be fully secured in the concha and not protruding out of

the ear at any point. (see Fig. 5)

Step 5. If the retainer or earplug doesn’t t properly (see Fig. 6 & 7) it can be removed and reinserted.

Removing Earplugs

For greater comfort twist the earplug gently to break the seal before removing it from the ear canal.

Caution: Rapid removal may damage the ear. It is not recommended to remove the earplugs by

pulling the cord. (see Fig. 8)

Cleaning and Disinfecting

These earplugs are reusable and should be cleaned with mild soap and warm water only. Allow to dry at

room temperature. Do not immerse the rocker switch assembly in water as this can clog the lter. Do not

use alcohol or other disinfectant as these may damage the earplugs. Do not use heat to dry the product.

Hard plastic parts may be wiped clean. Discard the product immediately if there is any sign of damage.

Earplugs

1. Always be sure that the complete product is:

a) Suitable for the application b) Fitted correctly c) Worn during all periods of exposure d) Replaced when necessary

2. This product may be adversely affected by certain chemical substances. Further information should be obtained from the

manufacturer.

3. Earplugs tted with a connecting cord should not be used where there is a risk that the cord may be caught up during use.

4. When used in the Open Mode against continuous noise, the product may not offer adequate protection in all operating

environments which may lead to noise induced hearing loss.

5. Although test data from ISL laboratory for peak noise reduction shows that the product offers increasing level of protection

against peak impulse noise up to 190 dB peak, it is recommended the product should be restricted to a maximum external

level of 160 dB in order to ensure the level effective to the ear remains below the Peak Exposure Limit Value of 140 dB.

6. In the unlikely event of the earplug tip becoming lodged in the ear canal, seek medical attention.

7. Failure to follow all instructions on the use of these personal protection products and/or failure to properly wear the complete product

during all periods of exposure may adversely affect the wearer’s health, lead to severe or life threatening illness or permanent disability.

8. When individuals are ring weapons and exposed to impulsive sounds, the severity of exposure is inuenced by the weapon,

ammunition, number of rounds red, and numerous other variables. Proper selection, t, use, and care of the hearing protector are

very important. All of these factors make it difcult to predict the required and/or actual protection obtained. Regardless of the hearing

protector being worn, the user should be alert to his or her own hearing. If during or after an exposure, tinnitus (ringing or buzzing in

the ears) is heard or the user’s hearing seems mufed or dulled, or for any other reason the user suspects a hearing problem, the t,

condition, and adequacy of the protector should be carefully checked and/or a more protective device or combination of devices (such

as earmuffs and earplugs together) should be worn. For those exposed to weapons re on a regular basis, periodic hearing evaluations

are advised.
