Introduction
Minuendo Smart alert earplugs (Earplug) is an in-ear hearing protector with
continuous personal exposure monitoring. It provides:
• Continuous personal noise exposure monitoring and data logging.
• Noise level and cumulative exposure indications, through audible, haptic
and LED feedback.
• Passive attenuation filtering with flat response for natural ambient sound.
• Data logging for synchronization to secure cloud data service.
First Use
When Earplug is turned ON for the first time the LED will blink PURPLE.
Connect the Earplug to the Dock (if available) or a PC connected with a Cable
to the Smart Alert cloud to download updates if needed and configure for first
use. If the Earplug is not connect as described, it will continue to function as
described herein. However, the data logging capability will not be available.
Charging and Power
Cable (if available):
Connect the charging cable to the Earplug and then to the power charger.
Plug the charger into a wall socket and switch the charger on. Earplug LED will
indicate status.
Dock (if available):
Insert the right-hand side of the Collar Unit [R] into an available station on
the Dock. Ensure that the Earplug is fully inserted.

Blinking GREEN x 4 GOOD > 9 hrs operational time remaining
Blinking ORANGE x 4 MEDIUM < 5 hrs operational time remaining
Blinking RED x 4 LOW < 30 mins operational time remaining
Low BatteryIndicator
When the battery level is LOW (< 30 mins remaining) the Earplug will beep
every 15 seconds. Place the Earplug on charge.
Low BatteryShut-down
If the battery level reaches a critically low state it will automatically turn OFF. The
Earplug must be recharged before further use. When turned ON the Earplug LED
will blink PURPLE, the Earplug must be connected to a Dock or the Cloud service
(via a PC and charging cable) to reset the internal timing clock before further use.
Safety Information
Please read before first use and follow all safety information contained with
these instructions. Retain them for future reference.
Warning:
• The protection afforded by the Earplug and your hearing health may be
severely impacted if you do not follow the instructions in this manual.
• Improper fit of this device will reduce its effectiveness in attenuating noise.
Consult these instructions for proper fit.
• Failure to act upon the Noise Alert or Exposure Alarm may increase your
risk of Noise-Induced Hearing Loss.
• Misuse or failure to wear hearing protection at all times when exposed to
hazardous noise may result in hearing loss or injury.
• The Earplug should not be used in environments that are considered
flammable or explosive atmospheres. The Earplug contains a battery
and electrical components that may cause ignition. Do not use it in
environments where sparks may cause fire or explosion.
• The Earplug should not be used where there is a risk that the Collar Unit to
Earpiece cable or the Collar Unit could be caught up during use.
• Do not submerge the Earplug into the water. Dry fully before charging or
connecting with the Dock.
• Do not puncture the seal at the end of the Earpiece nozzles. If damaged
replace the Earplug.
• To avoid the risk of choking Ear Tips or Ear Hooks should not be eaten or
placed in the mouth.

Caution:
• Ensure that the Earplug and EarTips are regularly inspected for serviceability.
• Do not put dirty or damaged EarTips into your ear. If uncertain, replace EarTips.
• Only use authorised Ear Tips detailed in this instruction manual.
• Do not remove Earpieces by pulling on the cable or Collar Unit.
• Sudden or fast removal of Earpieces out of the ear canal may damage the
eardrum.
• Do not tap or bang the Earpieces when fitted in your ear.
• Seek medical assistance if an Ear Tip remains in your ear when the
Earpiece is removed.
• The Earplug battery should be recharged on a frequent basis.
• Battery charging should be undertaken indoors.
• Do not use the Earplug if a fault is displayed via the LED or alternatively,
if the Cloud or Dock are being used; a product fault is notified to you by
email/SMS text message. Contact manufacturer for details.
• Ensure that the Earplug firmware is always at the latest version. Contact
manufacturer for details.
• The Earplug should not be used for more than 10 years from the date of
manufacture stated on the packaging.
Wearing and Fitting Instructions
Assemble Earpieces Before first use
Ear Hooks: (Reference Fig. 2)
Select the largest Ear Hook you think will fit comfortably. Put the Ear Hook (by
itself) into the ear. Rotate the Ear Hook to ensure the hook is secured in the
arch (concha) of the ear. Try a different size if preferred. When the preferred
size is selected, remove it from the ear and push it onto the base of the
corresponding Earpiece (L or R). Repeat the process for the opposite ear.
Ear Tips: (Reference Fig. 3)
Choose the style of ear tip, then the size of the ear tip you feel will provide a
comfortable but tight fit. Push it fully onto the nozzle of the earpiece. There
should be no gaps between the Ear Tip, the Ear Hook (if fitted) and the base
of the earpiece.
Advisory
• It is possible to wear the Earplug earpiece without the Ear Hook fitted.
• Video instructions for earpiece assembly and Ear Tip fitting at https://help.
minuendo.com/en/support/smart-alert-earplug
• The Ear Tips should be correctly fitted for optimal performance and comfort.
• Ears and ear canals can vary in size between Left and Right. Choose the
correct size for each ear.
Put Earplug On
Use both hands to pass the Collar Unit around the back of your neck. The
Collar Unit shall rest on your shoulders, with the R side on your right shoulder.

Advisory
• The Collar Unit can be worn over clothing, or underneath a jacket. Wearing
underneath a jacket may impact your awareness of the Earplug feedback;
Haptic may increase & audible signal may decrease.
• Avoid over-stretching the Collar Unit pulling it over your head or helmet (if
fitted).
• If using a helmet with a chin strap, fit the chin strap first.
Fit the assembled Earpieces into each ear.
Ensure the correct sized Ear Tip is fitted to the Earpiece. If using Foam Ear
Tips, gently compress and roll the Ear Tip ensuring there are no creases. Insert
Ear Tip into the ear canal. Apply gentle pressure to the Earpiece to hold it
while foam expands. The Earpiece should sit firmly in the ear.
Advisory
• Gently pull the ear outward to straighten the ear canal before inserting the
ear tip.
• The right combination of Ear Hook and Tip will ensure wearing comfort.
• Rotate Earpieces to align the hook into the concha (if using Ear Hooks).
Otherwise rotate to align the Earpiece nozzle within the ear canal.
Take Earplug Off
To remove the Earpieces from each ear, slowly pull and while twisting them.
Remove heavily soiled Ear Tips and discard in an appropriate waste collector.
Use both hands to remove the Collar Unit from around the back of your neck.
Place the Earplug on charge.
Advisory
• Avoid over-stretching the Collar Unit pulling it over your head or helmet (if
fitted).
• Remove helmet chin strap first , if fitted over the Earplug (Earpieces).

Earplug Warnings (Alerts and Alarms)
The Earplug provides feedback regarding noise level and cumulative average
exposure.
Noise Indicator (optional feature):
Activates when the noise level measured by either noise sensor in
each Earpiece has exceeded the alert threshold. The default threshold
approximately corresponds to 85 dB.
Blinking ORANGE
Noise Alert:
Activates when the noise level measured by either noise sensor in
each Earpiece has exceeded the alert threshold. The default threshold
approximately corresponds to 85 dB*. The Noise Alert system is designed
to reduce false alerts when the Earpiece is correctly fitted in your ear (*as
measured within the ear canal with the Earpiece correctly fitted).
