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 bodyworn 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.”
