Jobsite Aware Mode
Jobsite Aware mode uses an auxiliary microphone
to let you listen to the noises around you. When
surrounding noises reach loud levels, the mode
actively reduces volume to decrease the intensity of
those noises. Audio will continue to play while using
this feature.
To turn ON, push the left earbud button once. A tone
will play indicating jobsite aware mode is activated.
To turn OFF, push the left earbud button once again.
A tone will play indicating jobsite aware mode is
deactivated.
Once jobsite aware mode is activated, to change the
volume settings push the left earbud button twice.
Keep pushing left earbud button twice rapidly to
cycle through low, medium and high volume setting.
Troubleshooting Earbuds
Factory Reset
A factory reset must be performed before re-pairing
a lost/new earbud. If problems persist with audio or
phone call quality, perform a factory reset.
The charging case must be charged before starting
a factory reset.
To factory reset earbuds:
1. Place both earbuds into the charging case. Both
earbuds will illuminate and recognize the connec-
tion with the case.
2. Rapidly press the button on each earbud 4 times.
3. The earbuds will ash quickly, indicating they are
reset to factory settings.
Pairing Earbuds
1. After performing a factory reset, take both earbuds
out of the charging case and set them close to
each other. The earbuds will pair automatically.
2. The earbuds have been successfully factory reset
and re-paired when the earbuds charging light
indicator turns o󰀨 and ashes blue.
NOTE: If the earbuds ash red and green, the
factory reset was unsuccessful. Repeat a factory
reset and re-pairing instructions.
MAINTENANCE
WARNING
To reduce the risk of injury, always
unplug the charger and remove the
battery from the charger before performing any
maintenance. The charger and battery have no
internal serviceable parts. Never disassemble
the battery or charger.
Storage and Cleaning
Store your charger in a cool, dry place.
As a general practice, it is best to unplug battery
chargers and remove batteries when not in use. No
battery damage will occur, however, if the charger
and battery are left plugged in.
Gently clean the earbuds after each use.Remove ear
tips and wipe earbuds using a soft damp cloth. Do
not immerse. Do not remove mesh. Never use sharp
objects to clean the earbud inlet, as damage may
occur. Keep case clean of debris to ensure proper
earbud charging connection. If charge indicator lights
do not illuminate when earbuds are inserted in case,
ensure case is clean of dirt/debris and ear wings/
bands (if used) are properly attached.
Repairs
For repairs, return the tool, battery pack and charger
to the nearest authorized service center.
Noise Reduction Rating
WARNING
Rapid removal may damage the
eardrum. For greater control and
safety, remove ear tip slowly with twisting motion
to gradually break the seal.
The level of noise entering a person’s ear, when a
hearing protector is worn as directed, is closely ap-
proximated by the di󰀨erence between the A-weighted
environmental noise level and the NRR.
Example:
1. The environmental noise level as measured at
the ear is 92 dBA.
2. The NRR is 22 decibels (dB).
3. The level of noise entering the ear is approximately
equal to 70 dBA.
CAUTION
For noise environments dominated by
frequencies below 500 Hz, the C-
weighted environmental noise level should be used.
Improper t or inconsistent use of this device will
reduce its e󰀨ectiveness attenuating noise. Consult
the enclosed instructions for proper t.
Although hearing protectors can be recommended
for protection against the harmful e󰀨ects of impulsive
noise, the noise reduction rating (NRR) is based on
the attenuation of continuous noise and may not be
an accurate indicator of the protection attainable
against impulsive noise such as gunre.
For example, gunfire exposure depends on the
weapon type, number of rounds red, proper selec-
tion, t and use of earplugs, proper care of hearing
protection, etc.
The US EPA species the NRR as the measure
of hearing protector noise reduction. However,
MILWAUKEE makes no warranties as to the suit-
ability of the NRR for this purpose. Research sug-
gests that many users will receive less noise reduc-
tion than indicated by the NRR due to variation in
earplug t, earplug tting skill and motivation of the
user. It is recommended that the NRR be reduced
by 50% to better estimate typical workplace protec-
tion.
