2|ARGONAUT®COMMUNICATION EARPLUGS
Overview
The Aegisound Argonaut Communication Earplugs (ACE) are used with
Aegisound’s Argonaut DHPC headset, providing incoming communciations to the
ear. The Argonaut Communication Earplugs are also compatible with Aegisound’s
DANR THPC headset but do not provide active noise reduction functionality when
used with the DANR headset.
The Argonaut Communication Earplugs are compatible with Gentex Low Prole
Communication Earplugs (LPCCE) and Comply foam eartips.
Before Usage
Always evaluate the adequacy of your protective gear before entering
hazardous environments.
The wearer should ensure that:
•The earmuffs and earplugs are tted, adjusted, and maintained in
accordance with the manufacturer’s instructions (Improper t of this device
will reduce its effectiveness in attenuating noise – Consult the included
instructions for proper t)
•The earmuffs and earplugs have been inspected for serviceability
•The earmuffs and earplugs should be worn at all times in noisy
surroundings
The use of any hearing protective device will not guarantee adequate protection
for hearing loss for all persons under all circumstances. Consult your physician
or audiologist frequently when being exposed to high noise levels. If exposure
to high noise levels occurs during employment activities, also consult your
employer regularly.

Connecting ACE to Headset
1. Rotate the earcup to gain access to the earplug receptacle.
2. Grasp the earplug connector
and insert the connector into
either earcup by aligning the
red dot on the connector with
the red dot on the receptacle.
Gently press the connector
until it snaps in place.
3. To remove the connector,
grip the connector’s knurled
sleeve and pull in direction
indicated. DO NOT pull on
the earplug cable.

Attaching Eartips
Before use, inspect the earplug cable assembly for signs of damage or wear. See
the LPCCE User Manual for more detailed instructions for Gentex’s compatible
custom molded earplug products.
The nominal diameter designations of the Comply foam eartips, per EN 13819-1,
are as follows:
•Standard: 7 - 10 mm
•Slim: 8 - 12 mm
•Generic foam tips for the Argonaut Communication Earplug (ACE) come in two
different sizes: standard and slim
• Standard foam tips t most individuals
• If experiencing discomfort while using the standard foam tip, switch to
the slim foam tip
• Individuals with relatively small ear canals should use the slim foam tip
•The tip of the ACE is threaded and matches the foam tip threads
•Carefully, thread the foam tip on the ACE until the foam touches the
black housing
•Grip the housing and the foam tip and tighten an additional ¼ turn – Do not
over tighten
•This method ensures that anking sound paths are minimized

USER MANUAL |5
Fitting Earplugs
See the LPCCE User Manual for more detailed earplug tting instructions. The
instructions below apply to foam eartips.
1. Using the thumb and index nger, roll
the foam tip into the narrowest possible
crease-free cylinder
2. Reach over your head with your free
hand, pull your ear up and back, and
before it expands, insert the compressed
foam tip into your ear canal
3. Ensure that the foam tip is deeply
seated in the ear canal and hold it
to allow for expansion, such that it
cannot be easily seen by others when
fully inserted.
4. Fit the other ear in the same manner

6|ARGONAUT®COMMUNICATION EARPLUGS
Cable Routing
The earplug cable can be oriented straight down or over the ear, depending upon
the user’s preference.

USER MANUAL |7
If the headset is installed in a helmet, the helmet should be placed on the head so that
the earcups can be rotated away from the ears, allowing you to insert the earplugs
before donning the headset.

Fitting Headset
1. Position the headset so that the microphone is on the left side
2. Insert the right earplug into the right ear (Orientation not critical when using
Generic Foam Earplugs)
3. Insert the left earplug into the left ear
4. Place the headset on the head
5. Place the headset comfortably over the ears, ensuring that the outer ear is
completely seated in the earcups. Cinch the o-ring on the earplug cables to
prevent a snag hazard

Failure to comply with general safety precautions violates the safety intent of
this product and may result in bodily harm or damage to the product. Gentex
Corporation claims no liability for damage or injury resulting from a failure to
comply with the safety precautions outlined in this manual.
This product may be adversely affected by certain chemical substances.
Further information should be sought from the manufacturer.
The earplugs should not be used where there is a risk that the connecting cord
could be snagged during use.
The protection afforded by the earplugs will be severely impaired if:
•The earplugs are not tted and maintained in accordance with the
manufacturer’s instructions
•The earplugs are not regularly inspected for serviceability
•The earplugs are not worn at all times in noisy surroundings
Warning

USER MANUAL |11
Inserting or removing the earplugs too quickly may result in air pressure
or suction against the eardrum causing temporary pain. The earplugs
should be inserted or removed slowly with a twisting motion to prevent
excess pressure buildup. Gently moving the earplug while opening the
jaw fully may remove excess pressure buildup.
Prolonged use of earplugs (exceeding several hours) may result in
temporary soreness near the ear canal. Use of custom earplugs may
reduce the risk of this irritation when compared to expandable foam
type plugs. The use of earplugs may require a “break-in” period to
accustom the ear canal to the presence of the earplug.
In order to ensure maximum performance, the ear canal should be clean
and free of excess ear wax and debris before inserting the earplugs.
Long term usage of earplugs could result in the buildup of ear wax
within the ear. In the event that ear wax or debris becomes impacted in
the ear canal, seek medical consultation.
Custom earplugs should be cleaned periodically with warm, soapy water
to prevent buildup of dirt and bacteria. Generic earplugs should be
disposed of and replaced once they become soiled. Ear inammation,
otitis externa, or other infection could result from the use of dirty
earplugs. In the event of pain or discharge from the ear canal, seek
medical consultation.
Gentex custom t earplugs are made from an immunologically inert
material and allergic reactions would be rare. In the event an allergic
reaction is suspected, discontinue use and seek medical consultation.
DO NOT hang or swing the headset by the earplugs or the cables.
