Basic Operations

Installing Batteries: Power and Volume:

Install two 1.5V AA batteries as shown.
Close battery door until it clicks.

Press and hold the On/O/Volume
button for 2 seconds to power
headset. Turn On/O/Volume knob
clockwise to control volume.

Fitting Headset: Headband Padding:

Fully extend sliders and place cups
over ears so that the microphones
are facing forward. Then, tighten
headband using sliders.

For improved comfort, insert the Comfort
Pad into the headband holes from below
with the textured cushion facing down.
To remove the padding, simply hold the
headband securely, and push down on
the headband padding.

Basic Operations

Low battery warning:

BATTERY
LOW

Headset will give a “battery low” warning
every one minute when battery voltage
is low. Additional warnings will occur as
hearing protector powers down. Replace
batteries at this time.

Auto shut-o: Safe volume control: Music equalizer:

82 dB(A)

After 2 hours of non-activity, a 10-second
countdown will begin before hearing protector
automatically powers down. To reset auto shut­o, simply adjust volume knob.

After auto shut-o, turn On/O/Volume knob to
“o” position for 2 seconds, then back to “on.”

The safe volume control technology allows for
increased music volume while protecting your hearing,
by controling sound levels over an 8-hour work day.
Higher sound exposure is allowed for a period of time,
and then gradually reduced if necessary below the long
term average of 82 dB(A) for extended use.

IMPORTANT USER INFORMATION

!

CAUTION

For best protection, ear cushion sealing rings should seal rmly against head. Anything
that interferes with the seal — such as long hair (pull back to the extent possible),
thickorpoorlyttingeyeglass temples, pencils or caps — will lessen the protection.

Do not bend or reshape the headband, as this will cause a loose t and sound leakage.

Earmus must be regularly inspected for cracks or worn parts and replaced as needed.
Typical life for foam cushion sealing rings is six months.

Clean the exterior of the hearing protector regularly with soap and warm water.
Donotimmerse in water.

Do not store the hearing protector behind a windshield or at temperatures

+

131°F

above131°F(55°C).

Certain chemical substances may damage this product. Contact the manufacturer
formoreinformation.

TO REDUCE THE RISKS ASSOCIATED WITH HARMFUL NOISE OR CHEMICALS:

If instructions are not followed, bodily injury may result or protection may be severely aected.

When interference increases or the sound level becomes too weak, it is time to change the
batteries.

Do not store with the batteries installed. A leaking battery may cause bodily injury or damage to
the hearing protector.

These hearing protectors help reduce exposure to hazardous noise and other loud sounds.
Misuse or failure to wear hearing protectors at all times when you are exposed to noise may
result in hearing loss or injury.

If there is any drainage from your ear or if you have an ear infection, consult with your physician
before wearing hearing protection. Failure to do so may result in hearing loss or injury.

For proper use, see user instructions or call 3M Technical Service toll free at 1-800-494-3552.

NOISE REDUCTION RATING (NRR)

NOISE REDUCTION RATING

The Environmental Protection Agency (EPA) has selected the Noise Reduction Rating
(NRR) as the measure of a hearing protector’s noise-reducing capabilities. 3M makes
no warranties as to the suitability of the NRR as a measure of actual protection from
any noise level since such protection depends on the sound level (loudness), how long
you listen to the loud sound and how well you t the earmu over your ears. Although
hearing protectors can be recommended for protection against harmful eects of
impulse noise, the NRR is based on the attenuation of continuous noise and may not be
an accurate indicator of the protection attainable against impulse noise such as gunre.

The NRR for the Worktunes™ Wireless is 25 dB(A). Improper tof this
device will reduce its eectiveness in attenuating noise. Consult the
enclosed instructions for proper t.

The level of noise entering a person’s ear when a hearing protector is
worn as directed is closely approximated by the dierence between
the A-weighted environmental noise level and the NRR.

Attenuation (ANSI S3.19 – 1974)

EXAMPLE

1. The environmental noise level as measured at the ear is 92 decibels (dBA).

2. The NRR is 25 dB(A).

3. The level of noise entering the ear is approximately 67 dB(A).

CAUTION
For noise environments dominated
by frequencies below 500 Hz, the
C-weighted environmental noise level
should be used. TheNRR used in the
above example was achieved under
laboratory conditions.

SUBPART B

AUDIO INPUT LEVEL
The audio level in the hearing protector is dependent on the audio input level.
To prevent harmful noise levels, the hearing protector audio level is limited to 82
dB(A) when connected to a Personal Music Player (PMP). If the hearing protector
is connected to a PMP or other device with a very high output level, it is the user’s
responsibility to set the audio input level to a safe level. The maximum permitted
audio input level for 8 hours of usage time, compressed speech and music is 188 mV.

WARRANTY
The Worktunes™ Wireless is warranted to be free of defects in material and
workmanship for a period of one (1) year from the date of original purchase. 3M will,
at its option, repair or replace without charge, except for transportation costs, parts
that fail under normal use and service when operated and maintained in accordance
with our instructions. This warranty does not cover damage caused by misuse, abuse
or unauthorized modications. Proof of purchase is required to verify eligibility.
