Furthermore if the device is developed for the US market and/or Canada market, it
shall comply to the FCC and/or IC approval requirements:
This device is to be used only for mobile and fixed application. The antenna(s) used
for this transmitter must be installed to provide a separation distance of at least 20
cm from all persons and must not be co-located or operating in conjunction with any
other antenna or transmitter. End-Users must be provided with transmitter
operation conditions for satisfying RF exposure compliance. OEM integrators must
ensure that the end user has no manual instructions to remove or install the GE864-
