RF exposure
CAUTION! 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.

1. 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.
