NRR 23dB Tested in accordance with ANSI s3.19-1974 In-ear
The NRR calculated from these bboratorybased attenuation data is 23
Improper fit of this device will reduce its effectiveness in attenuating noise. Consult instructions for proper fit. The level of noise entering a person’s ears 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:
- The environmental noise level as measured at the ear is 91 dB(A).
- The NRR is 23 decibels (dB)
- The level of noise entering the ear is approximately equal to 91 dB-23 68 dB(A).
Tips
- Before use. please read the manual carefully and keep it for future reference.
- Charge earplugs completely before first use.
- If the earplugs cannot be found by your device, please check whether it is in pairing mode. if left unconnected for a long time, the earplugs will exit pairing mode; if a procedure error of your device occurs, reboot it; if a procedure error of the earplugs occurs, reboot or reset it.
Warnings
- Never disassemble or modify your earplugs or charging case for any reason.
- Do not store earplugs or charging cases in extrenme temperatures (Below 32°F or 110°F).
- Recharge before use if earplugs are left unused for Over two weeks.
- Do not use harsh chemicals to clean earplugs or charging cases.
- Keep earplugs and charging case dry.
FCC
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions
- this device may not cause harmful interference, and
- this device must accept any interference received, including interference that may cause undesired operation.
CAUTION: For noise environments dominated by frequencies below 500Hz, the C-weighted environment noise level should be used.
Although hearing protectors can be recommended for protection against the harmful effects of impulsive noise, the 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.
FCC Requirement
changes or modifications not expressly approved by the party responsible for
compliance could void the user s authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits
