3.2. FCC AND IC INFORMATION
This device complies with Part 15 of the FCC rules and ISED
Canada license-exempt Radio Standards Specifications.
Operation is subject to the following two conditions: (1) This
device may not cause harmful interference, and (2) this
device must accept any interference received, including
interference that may cause undesirable operation.
NOTE: This device 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 device 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 device does cause harmful interference,
which can be determined by turning the device 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 distance between the two
interfering devices.
• Consult 3M Technical Services.
This portable device with its antenna complies with FCC/IC RF
Exposure limits for general population / uncontrolled exposure.
The antenna used for this device must not be co-located or
operating in conjunction with any other antenna or transmitter.
Changes or modifications to the equipment not expressly
approved by the party responsible for compliance could void
the user's authority to operate the equipment.

4. EXPLANATION OF STANDARD
TABLES
The sound attenuation was obtained with the device powered
off.
4.1. EUROPE AND ANZ
3M strongly recommends personal fit testing of hearing
protectors. Research suggests that users may receive less
noise reduction than indicated by the attenuation label value(s)
on the packaging due to variation in fit, fitting skill, and
motivation of the user. Refer to applicable regulations and
guidance on how to adjust attenuation label value(s).
In the absence of applicable regulations, it is recommended
that the attenuation label value(s) be reduced to better estimate
typical protection.
