Body-Worn Operation
This device was tested for typical body-worn operations with the back
of the portable music player kept 5mm from the body. To maintain
compliance requirements, use only belt-clips, holsters or similar
accessories that maintain a 5mm separation distance between the
user’s body and the back of the portable music player, including the
antenna. The use of belt-clips, holsters and similar accessories should
not contain metallic components in its assembly. The use of
accessories that do not satisfy these requirements may not comply
with CE RF exposure 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
typical user can easily understand the information, to acquire the
required body-worn accessories to maintain compliance. Instructions
on how to place and orient a device in body-worn accessories, in
accordance with the test results, should also be included in the user
instructions. All supported body-worn accessory operating
configurations must be clearly disclosed to users through conspicuous
instructions in the user guide and user manual to ensure unsupported
operations are avoided. All body-worn accessories containing metallic
components must be tested for compliance and clearly identified in the
operating manual. The instruction must inform users to avoid using
other body-worn accessories containing metallic components to
ensure RF exposure compliance.”
