User's Manual
A GMRS license requires Form 605 and Form 159. A (PLM) license requires Form 601 and Form 159
Schedule D and H. Please note that application fees will be applicable.
You can obtain a copy of the FCC Forms mentioned above by calling 1-800-418-3676. Further detailed
instructions are available by calling the FCC at 1-888-225-5322. In addition, you can download the forms,
register on-line, and obtain further information at the FCC’s Web site: www.fcc.gov/formpage.html
Safety information
Your wireless transceiver contains low power transmitter. When the transmitter is activated it sends out
radio frequency (RF) signals. This device is authorized to operate at a duty factor not exceed 50%.Use
only the supplied antenna. Unauthorized antennas, modications, or attachments could damage the
transmitter and violate FCC regulations
GMRS License :
Use of GMRS radios within the United States requires a FCC GMRS license. An individual 18 years of age
or older, who is not a representative of a foreign government is eligible to apply for a GMRS system license.
You will need two forms from the FCC, FCC Form 159 and FCC Form 605 Main Form and Schedule F. You
can nd the forms online at http://www.fcc.gov/formpage.html, or call 1-800-418-3676.
NRR
The NRR attenuation data are displayed on page 11.
Improper t of this device will reduce its effectiveness in attenuating noise. Consult this manual for
proper tting instructions. For further information, please write Aearo Company, 8001 Woodland Drive,
Indianapolis, Indiana 46278. 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 niose level
and the NRR.
Example:
1. The environmental noise level as
measured as the ear is 92 dBA
2. The NRR is 22 decibels (dB)
3. The level of noise entering the ear
is approximately equal to 70 dBA.
The NRR used in the above example was acheived under laboratory conditions. Although hearing
protectors can be recomended 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 gunre.
