the radio receiver earphones is 82 dB(A). The microphone's wind protector, which eliminates wind noise etc., should be kept clean and changed when
necessary. If the above-mentioned recommendations are not followed, the protection and function afforded by the earmuffs may be severely impaired.
AUDIO INPUT LEVELS*: The audio levels in the earphones is dependent on the audio input level. To prevent harmful noise levels in the earphones never
exceed the values and usage described in figure A:1. Mean/average level of electrical input. Maximum permitted audio input level for 8 hours of usage
time, compressed speech and music U=96 mV. See figure A:1 and Table 1.
WARNING: Listening to music, or any other sound, at a high volume over time can cause permanent damage to your hearing. Noise-induced
hearing loss can occur even when you are enjoying music on a personal listening device. Exposures to high volume over time can cause perma-
nent damage. Users should enjoy their favorite music safely and avoid potential hearing loss. When it comes to safe use of personal listening devices,
we recommend that you listen responsibly, including listening at no more than 80% of a device's maximum volume for a maximum of 90 minutes per
day at such levels. If you listen at a lower volume, you can listen for a longer time. By contrast, at higher volumes, you should listen for a shorter time.
Noise-induced hearing loss is 100% permanent, but 100% preventable. The user is responsible for the proper selection, use, care and maintenance
of this device. Improper s election (including under/over protection), use or maintenance may lead to serious hearing loss. If there are any questions
concerning this product contact your safety s upervisor or Sperian Hearing Protection, LLC.
