****** Page 4 ****** 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. 6 Auto shut-off: 2-HOUR AUTO SHUT-OFF After 2 hours of non-activity, a 10-second countdown will begin before hearing protector automatically powers down. To reset auto shut- off, simply adjust volume knob. After auto shut-off, turn On/Off/Volume knob to “off ” position for 2 seconds, then back to “on.” Safe volume control: O 82 dB(A) 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. Music equalizer: 00 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.

****** Page 8 ****** IMPORTANT USER INFORMATION For best protection, ear cushion sealing rings should seal firmly against 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. Do not bend or reshape the headband, as this will cause a loose fit and sound leakage. Earmuffs 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 above 13fF (550C). Certain chemical substances may damage this product. Contact the manufacturer for more information. 14 ACAUTION TO REDUCE THE RISKS ASSOCIATED WITH HARMFUL NOISE OR CHEMICALS: If instructions are not followed, bodily injury may result or protection may be severely affected. 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.

****** Page 9 ****** NOISE REDUCTION RATING (NRR) 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. The N RR for the Worktunes'” Wireless is 25 dB(A). Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the enclosed instructions for proper fit. 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. Attenuation (ANSI S3.19 – 1974) NOISE REDUCTION RATING 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). 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.

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 WorktunesT” 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 modifications. Proof of purchase is required to verify eligibility. 17
