TESTING AND APPROVALS

The Noise Reduction Rating (NRR) is third-party tested in accordance with ANSI S3.191974.

Note: This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures.

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

This Class B digital apparatus complies with Canadian ICES-003.

USE LIMITATIONS

The level of noise entering a person's ear when hearing protection is worn as directed is closely approximated by the difference between the A-weighted environmental noise level and the NRR.

Example:
If the environmental noise level measured at the ear is 92 dB(A), and the NRR is 24 decibels (dB), the level of noise entering the ear is approximately equal to 68 dB(A): 92 dB(A) - 24 dB(A) = 68 dB(A).

For noise environments dominated by frequencies below 500 Hz, use C-weighted environmental noise levels.

The EPA has selected the NRR as a measure of a hearing protector's noise reducing capabilities. There is no warranty as to the suitability of the NRR as a measure of the actual workplace protection since such protection is highly dependent on user training, motivation, and utilization. Refer to the above instructions for proper fit. A better estimate of workplace protection can be obtained by derating the labeled NRR of this, or any other hearing protector, by 50%.

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. The noise reduction capability of this hearing protector against impulsive noise may be estimated by referring to the attenuation performance of the hearing protector at the frequency of the impulsive noise exposure as provided in the attenuation data on the package. To estimate the noise reduction capability of this hearing protector against impulsive noise, refer to the Attenuation Data above or on the product package. If the frequency of the impulsive noise is 2000 hertz (Hz), for example, the mean (average) reduction of noise attained by test subjects at the frequency was 34.7 decibels (dB). Using the standard deviation of ± 3.2 dB. the estimated noise reduction at 2000 Hz would range from 31.5 dB to 37.9 dB. Refer to manufacturer of equipment producing the impulsive noise to determine the frequency.

Check performance before using this product. This product contains small parts that may present a choking hazard. Not for children under 3 years. Hearing protectors in general can block external sounds such as warning calls, alarms, and other important signals. Pay special attention to what is happening around you when wearing hearing protectors. Setting the volume too high can further reduce your ability to hear external sounds, which could expose you to considerable risk and lead to serious accidents. Adapt the volume to your working situation. These ear muffs contain batteries and electrical components that may cause ignition in flammable or explosive atmospheres. DO NOT use in environments where sparks may cause a fire or explosion. Misuse can result in injury or death. DO NOT use the radio while driving a car. The radio and muffs could block surrounding sounds and increase the risk of having an accident. Failure to follow the warnings and instructions in this User Instruction Manual can result in serious personal injury or death.
