* If using the RF module in a portable application (for example - if the module is used in
a handheld device and the antenna is less than 20cm from the human body when the
device is in operation): The integrator is responsible for passing additional SAR (Specific
Absorption Rate) testing based on FCC rules 2.1091 and FCC Guidelines for Human
Exposure to Radio Frequency Electromagnetic Fields, OET Bulletin and Supplement C.
The testing results will be submitted to the FCC for approval prior to selling the
integrated unit. The required SAR testing measures emissions from the module and how
they affect the person.
RF Exposure
WARNING: To satisfy FCC RF exposure requirements for mobile transmitting devices, a
separation distance of 20 cm or more should be maintained between the antenna of this device
and persons during device operation. To ensure compliance, operations at closer than this
distance are not recommended. The antenna used for this transmitter must not be co-located
in conjunction with any other antenna or transmitter.
The preceding statement must be included as a CAUTION statement in OEM product
manuals in order to alert users of FCC RF Exposure compliance.
