Notice

OEM integrators and installers are instructed that the phrase. This device contains

transmitter FCC ID:

RI7CC864-DUAL must be placed on the outside of the host.

Warning: Exposure to Radio Frequency Radiation The radiated output

power of this device is far below the FCC radio frequency exposure

limits. Nevertheless, the device should be used in such a manner that

the potential for human contact during normal operation is minimized.

In order to avoid the possibility of exceeding the FCC radio

frequency exposure limits, human proximity to the antenna should

not be less than 20cm during normal operation. The gain of the

antenna for Cellular band must not exceed

-2.0 dBi.

The gain of the antenna for PCS band must not exceed -3.0

dBi.
