Incoming Calls
Phone call ring will sound in right earbud to notify of
the incoming call. To answer, push the right earbud
button, this will pause music if playing and take the
call.
To reject a call, push the right earbud button twice.
To hang up the call, push the right earbud button. If
music was previously playing it will resume playing
from the pause.
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 flash 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 off and flashes blue.
NOTE: If the earbuds flash red and green, the
factory reset was unsuccessful. Repeat a factory
reset and re-pairing instructions.
To reduce the risk of injury, always
WARNING
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.
Maintenance and Storage
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.
For repairs, return the tool, battery pack and charger
to the nearest authorized service center.
Noise Reduction Rating
Rapid removal may damage the
WARNING
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 difference 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.
For noise environments dominated by
CAUTION
frequencies below 500 Hz, the C-
weighted environmental noise level should be used.
Improper fit or inconsistent use of this device will
reduce its effectiveness attenuating noise. Consult
the enclosed instructions for proper fit.
Although hearing protectors can be recommended
for protection against the harmful effects 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 gunfire.
For example, gunfire exposure depends on the
weapon type, number of rounds fired, proper selec-
tion, fit and use of earplugs, proper care of hearing
protection, etc.
The US EPA specifies 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 fit, earplug fitting skill and motivation of the
user. It is recommended that the NRR be reduced
by 50% to better estimate typical workplace protec-
tion.
