2.2.2. FCC Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with minimum distance 20cm between the radiator and
your body as well as kept minimum 20cm from radio antenna depending on the Mobile status of this
module usage. This module should NOT be installed and operating simultaneously with other radio. The
manual of the host system, which uses M85, must include RF exposure warning statement to advice user
should keep minimum 20cm from the radio antenna of M85 module depending on the Mobile status. Note:
If a portable device (such as PDA) uses M85 module, the device needs to do permissive change and SAR
testing.
The following list indicates the performance of antenna gain in certificate testing.
