Body-Wornoperation
This device was tested for typical body-worn operations with the back
of the portable music player kept 5mm. from the body. To maintain c o
mpliance requirements, use only belt-clips, holsters or similar acce ss
ories that maintain a 5mm separation distance between the user’s Bo
dy and the back of the Portable music player, including the antenn
a. The use of belt-clips, holsters and similar accessories should not c
ontain metallic components in its assembly. The use of accessories t
hat do not satisfy these requirements may not comply with CE RF ex
posure requirements, and should be avoided.
Body-worn accessory exposure conditions “Specific information must
be included in the operating manuals to enable users to select
body-worn accessories that meet the minimum test separation
distance requirements. Users must be fully informed of
the operating requirements and restrictions, to the extent that the ty pi
cal user can easily understand the information, to acquire the requi re
d body-worn accessories to maintain compliance. Instructions on h ow
to place and orient a device in body-worn accessories, in accorda nce
with the test results, should also be included in the user instruct ions.
All supported bodyworn accessory operating configurations mus t be cl
early disclosed to users through conspicuous instructions in the user
guide and user manual to ensure unsupported operations are av oided.
All body-worn accessories containing metallic components mu st be t
ested for compliance and clearly identified in the operating man ual. T
he instruction must inform users to avoid using other body-wor n acc
essories containing metallic components to ensure RFexposure compli
