BASIC OPERATIONS

Installing Batteries

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

Note:

• Do not mix old and new batteries.
• Do not mix alkaline, standard or rechargeable batteries.

Power and Volume
Press and hold the On/Off/Volume button for 2 seconds to power hearing protector. Turn the knob to adjust the volume up or down.

Fitting Headset:
Fully extend sliders and place cups over ears. Then, tighten headband using sliders.

Headband Padding:

After auto shut-off, press and hold the On/Off/ Volume knob for 2 seconds to turn back on.

Safe Volume Control:
Safe Volume Control Technology allows for increased music volume while protecting your hearing, by controlling 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.

Music Equalizer:
Press and Hold the Source button. The device will cycle through the three equalizer modes (Pop, Rock & Flat), then release the button when you reach the desired mode.

AM/FM Mode

AM/FM Radio Mode allows you to scan through all radio frequencies, save your favorite stations, and recall your saved stations.

SAFETY INFORMATION

Please read, understand, and follow all safety information contained in these instructions prior to the use of this electronic hearing protection product. Retain these instructions for future reference.

Intended Use:
This electronic hearing protection device is intended to help protect against harmful noise. This electronic hearing protection device is used in loud-noise environments. Use in any other application has not been evaluated by 3M and may lead to an unsafe condition.
Explanation of Signal Word Consequences

WARNING:
Indicates a hazardous situation which, if not avoided, could result in serious injury or death.

CAUTION:
Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury and/or property damage .

WARNING
These hearing protectors help reduce exposure to hazardous noise and other loud sounds. Misuse or failure to wear hearing protectors at all times that you are exposed to noise 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. In Canada, call 1-800-267-4414.

To reduce the risks associated with hazardous voltage and fire:

• Never use this product, or charge/replace batteries, in an explosive environment.
• Do not mix old and new batteries.
• Do not mix alkaline, standard, or rechargeable batteries.
• Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instructions.
• When using a 3M™ Alpha 1100 Li-Ion Battery Pack, see instructions provided with Battery Pack for additional safety information. Only charge using 3rd party certified (such as UL, lntertek, etc.) equipment.

To reduce the risks associated with harmful noise:

• Always wear hearing protectors when you are exposed to noise.
• Ensure hearing protection is properly fitted. Follow any fitting instructions included with this product.
• Do not bend or reshape the headband, as this will cause a loose fit and sound leakage.
• For best protection, the ear cushions should seal firmly against your head. Anything that interferes with the seal such as long hair (pull back to the extent possible), thick or poorly fitting eyeglass temples, pencils or caps will lessen the protection.
• Earmuffs must be regularly inspected for cracks, worn parts, and for proper fitting. Replace as needed.
• Do not immerse in water. Clean with a damp cloth and mild soap. Do not use harsh or abrasive chemicals.
• Do not store the hearing protector in direct sunlight or at temperature above 131 ° F (55° C). For example, behind a windshield or in a window.
• Do not change between ‘Safe Volume Control’ and limiter· settings
  during a single workday

CAUTION
To reduce the risks associated with chemical exposure and fire:

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

NOISE REDUCTION RATING (NRRl

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 fit the earmuff over your ears. Although hearing protectors can be recommended for protection against harmful effects 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 gunfire.

When worn according to the User Instructions, this hearing protector helps reduce exposure to both continuous noises, such as industrial noises and noises from vehicles and aircraft, as well as very loud impulse noises, such as gunfire. It is difficult to predict the required and/or actual hearing protection obtained during exposure to impulse noises. For gunfire, the weapon type, number of rounds fired, proper selection, fit and use of hearing protection, proper care of hearing protection, and other variables will impact performance. If your hearing seems dulled or you hear a ringing or buzzing during or after any noise exposure (including gunfire), or for any other reason you suspect a hearing problem, your hearing may be at risk. To learn more about hearing protection for impulse noise, visit www.3M.com/hearing.

The NRR may overestimate the hearing protection provided during typical use due to variation in fit, fitting skill and motivation of the user. 3M recommends the NRR be reduced by 50% or in accordance with applicable regulations, for estimating the amount of noise reduction provided.
The NRR for the Work Tunes™ Connect+ AM/FM is 24 dB(A). Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the enclosed instructions for proper fit.

The EPA references to Federal relate to US Federal laws.

Attenuation Data (ANSI 53.19 -1974)

NOISE REDUCTION RATING [NRRJ

The level of noise entering a person’s ear when a hearing protector is worn as directed is closely approximated 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 decibels dB(A).
2. The NRR is 24 dB(A),
3. The level of noise entering the ear is approximately 68 dB(A).

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

AS/NZS 1270:2002

SLC80 27.9 dB Class 5 Clamping Force: 9.8 N Mass: 342 g

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 109 mV.

WARRANTY
The Worktunes™ Connect+ AM/FM Hearing Protector 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 modifications. Proof of purchase is required to verify eligibility.
