The CR45-A-53, CR45-A-58, and CR45-A-58L transceivers, used in

conjunction with 28, 31 and 37 dBi gain antennas, are to be used in point-to-

point applications only. The transceivers can be provided with or without an

integral antenna. If the transceiver is provided without an integral antenna,

then antennas used for these transmitters shall be professionally installed on

permanent structures for outdoor operations. The installer is responsible for

ensuring that the systems using high-gain, directional antennas are used

exclusively for fixed, point-to-point operations.

The installer shall mount all transmit antennas so as to comply with the limits

for human exposure to radio frequency (RF) fields per paragraph 1.1307 of

the Federal Communications Commission (FCC) Regulations. The FCC

requirements incorporate limits for Maximum Permissible Exposure (MPE)

in terms of electric field strength, magnetic field strength, and power density.

The CR45A transceivers are to be installed on customers' rooftops and

towers designated for fixed wireless applications. Table 1 specifies the

minimum distance that must be maintained between the antenna and any

areas where persons may have access, such as rooftop walkways and

sidewalks, as well as through windows and other RF-transparent areas behind

which persons may be located.

CAUTION: To comply with FCC RF exposure requirements, antennas used

for this device must be installed to provide a separation distance

of at least 15m(5 feet) from all persons to satisfy RF exposure

compliance.
