FCC RF Exposure requirement
In order to comply with the FCC RF exposure requirements, the ETII RF may be used only
with the antenna that has been tested and certified. The certified antenna is located on the module
and has a permanent connection to the ET II RF Module:
A minimum separation distance of 20 cm must be maintained from the antenna to any nearby
persons.

Connections marked “DIO to Microcontroller” are used for control of external circuits. This allows the
RF control board module to be combined with various lighting control circuits on an external PCB
such as Triac Dimmers, FET Dimmers and Relays. The external PCB is independent from the RF
Module and has no direct impact on the radio communication.
RF Exposure / Final Configuration
In order to comply with Part 15.212(a)(vii), “The modular transmitter must comply with any applicable
RF exposure requirements in its final configuration”. The ET II RF Module will only be used in
products that Vantage Controls has designed and tested to ensure that they meet the RF exposure
requirements.
