The device is not a portable device (i.e. intended to be worn on the body or be hand-held), so it is classified as being either a mobile device or a fixed
mounted device. The userís manual specifies a minimum separation distance of at least 20cm, consistent with this classification.

FCC part 1.1310, Table 1 limits the power density for uncontrolled exposure. The power density, Pd (mW/cm2 ) calculated from the maximum EIRP, Pt
(mW) and the distance, d (m), between the transmitting antenna and the closest person, can be calculated using:

                                               Pd = Pt / (4*pi*d2)

The device is not a portable device (i.e. intended to be worn on the body or be hand-held), so it is classified as a fixed mounted device. The userís
manual specifies a minimum separation distance of at least 35cm, consistent with this classification.

FCC part 1.1310, Table 1 limits the power density for uncontrolled exposure. The power density, Pd (mW/cm2 ) calculated from the maximum EIRP,
Pt (mW) and the distance, d (m), between the transmitting antenna and the closest person, can be calculated using:
