3M™PELTOR™WS™
LiteCom Plus Headsets
Description
3M™PELTOR™WS™LiteCom Plus Headsets with Bluetooth®
opens up a world of communication. You become a mobile,
hands-free communication center, the built-in two-way radio

Fitting Instructions
Inspect the hearing protector before each use. If damaged,
select an undamaged hearing protector or avoid the noisy
environment.
When additional personal protective equipment is necessary
(e.g. safety glasses, respirators, etc.), select exible, low
prole temples or straps to minimize interference with the
earmu cushion. Remove all other unnecessary articles (e.g.
hair, hats, jewelry, headphones, hygiene covers, etc.) that
could interfere with the seal of the earmu cushion and
reduce the protection of the earmu.
Headband Headset
To t the hearing protector:
1. Slide out the cups and tilt the top of the cup out, as the
cable must be on the outside of the headband (Fig 1).
2. Pull the cups apart and place the earmus over the ears
so that the cushions form a snug seal around the ears.
3. Adjust the height of the cups by sliding them up or down
while holding the headband in place (Fig 2).
4. The headband should be positioned across the top of
your head (Fig 3).
Neckband Headset
To t the hearing protector:
1. Place the cups in position over the ears (Fig 1).
2. Keep the cups in position, place the head strap on top of
your head and lock it tight in position (Fig 2).
3. The head strap should be positioned across the top of
your head and should support the weight of the headset
(Fig 3).
Caution: The neckband earmus must be worn with
the head strap correctly attached to keep them rmly
in position to maintain an eective acoustic seal. The
protection level provided by neckband earmus may be
reduced if the head straps are not worn correctly.

Helmet Attach Headset
To t the hearing protector:
• Fit the cup: Push the attachment blade rmly into the slot
on the side of the helmet until it clicks into place (Fig 1 & 2)
• Working position: With the cups over the ears press the
arms inwards until you hear a click on both sides indicating
a rm seal (Fig 3).
• Stand-by position: Lift the cups to the xed stand-by
position. In a noisy environment the ear mus must be
worn in the working position at all times (Fig 4).
• Parking position: First lift the cups to the stand-by position
(Fig 4), then rotate them up to the next xed position.
• Ventilation mode: Avoid placing the cups against the
helmet as this prevents ventilation (Fig 5).
• Storage mode: When the helmet is not in use, lower the
earmus and press them inward. Keep the cups clean and
dry and store at normal room temperature.

Fit Check
When hearing protectors are correctly worn, your voice
should sound hollow and sounds around you should not
sound as loud as before.
Hearing Protector Fit Testing the 3M™
E-A-Rt™Dual-Ear Validation System
The success of your hearing conservation program requires
more than oering earplugs or earmus. Each worker
needs to wear the most eective hearing protector for the
environment and the correct t for their unique anatomy.
With 3M™ E-A-Rt™Dual-Ear Validation System, you can
quickly identify how much protection each worker receives
from their 3M hearing protectors.
The Technology Behind 3M™ E-A-Rt™
The 3M™ E-A-Rt™Dual-Ear Validation System is based on
Field Microphone-In-Real Ear (F-MIRE) technology that
measures the eectiveness of hearing protectors from inside
a worker’s ears, providing accurate, quantitative results.
The tester wears a pair of modied 3M™probed hearing
protectors connected to a dual-element microphone. A
loudspeaker is placed in front of the tester. When it emits a
broadband noise, the dual-element microphone measures the
signal in the ear canal and outside the ear plug. In less than
ve seconds, the dierence between the two measurements
is calculated and a Personal Attenuation Rating (PAR) is
displayed.
It Starts with PAR
The 3M™ E-A-Rt™Validation System puts the worker in the
context of their noise environment and helps you understand
their level of attenuation.
The results you get from the 3M™ E-A-Rt™is displayed as a
PAR. The PAR is a numerical value that shows the reduction in
sound level within the ear when a hearing protector is worn.
The resulting PAR, combined with the worker’s exposure
to noise, is used to determine if a worker is receiving
appropriate protection from the noise hazard.
Knowing the PAR lets you identify workers who are
inadequately protected, so you can provide real-time
intervention and training.
Key Benets of the 3M™ E-A-Rt™
Dual-Ear Validation System include:
• Tests both ears simultaneously in less than 5 seconds
• Science-based, quantitative testing
• Fast, clear, and accurate results
• Tests 7 frequencies 125Hz to 8000Hz
•3M™ Earplug, earmu and headset (comms) testing

* These earmus were tested in combination with the HC600 industrial safety helmet using the P3G adapter and may give
dierent levels of protection if tted to dierent helmets.
Mean = Mean attenuation value derived from testing in accordance with AS/NZS 1270:2002.
SD = Standard Deviation derived from testing in accordance with AS/NZS 1270:2002.
Mean-SD = Mean attenuation value minus Standard Deviation
SLC80 = Single number rating commonly used in Australia and New Zealand to compare acoustic performance of hearing
protectors. The subscript ‘80’ indicates that in well managed hearing protector programs, the protection provided is expected to
equal or exceed the SLC80 in 80% of protector-wearer noise spectrum combinations.
Class = A simplied process for selecting hearing protectors based on the wearers 8-hour equivalent continuous A-weighted
sound pressure level.
3M strongly recommends personal t 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 t, tting 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 eectiveness of a hearing protector reduces dramatically when the hearing protector does not t properly, is incorrectly
inserted or is not worn 100% of the time during ALL hazardous noise events. Removal of the hearing protector, even for brief
moments, substantially reduces protection and greatly increases the risk of hearing damage.

Cleaning and Maintenance
Follow recommended care and cleaning instructions in order
to maintain best noise reduction and function.
Cleaning
•Carry out a visual battery condition check. Replace if
battery leakage or defects are detected.
•Use a cloth wetted with soap and warm water to clean the
outer shells, headband and ear cushions.
NOTE: Do NOT immerse the hearing protector in water.
If the hearing protector gets wet from rain or sweat, turn
the earmus outwards, remove the ear cushions and foam
liners, and allow to dry before reassembly. The ear cushions
and foam liners may deteriorate with use and should be
examined at regular intervals for cracking or other damage.
When used regularly, 3M recommends replacing the foam
liners and ear cushions at least twice a year to maintain
consistent attenuation, hygiene, and comfort. In hot and
humid environments more frequent changes may be required
to maintain acceptable hygiene. If an ear cushion is damaged,
it should be replaced.
Maintenance - Changing the Hygiene Kit
Cushions and inserts can be replaced by using the approved
Hygiene Kits for your 3M
™
PELTOR
™
Product. See ‘Ordering
Information’ section.
1. Remove the cushions and inserts as shown.
2. Replace the worn or damaged cushions and insert with the
new pair from the approved hygiene kit.
•3M
™
PELTOR
™
HY100A Clean Hygiene Pads can be applied
onto the earmu cushions to help absorb sweat and
moisture for improved comfort and hygiene.
Storage
• Store the product in a clean and dry area before and after
use.
• Remove battery before storing the product for extended
periods
• Always store the product in the original packaging and
away from any sources of direct heat or sunlight, dust and
damaging chemicals.
