This device was tested for typical body-worn operations with the back of
the phone kept 0.39inches (1cm) between the user's body and the back of

between the user's body and the back of the phone, and have not been
tested for typical body-worn operations may not comply with FCC RF
exposure limits and should be avoided.

modifications to the antenna) could impair call quality, damage the phone,
void your warranty and/or violate FCC regulations.
Don't use the phone with a damaged antenna. A damaged antenna could

antenna.
