                   RF Exposure Compliance Requirement
                    ID ISC.LRMU1000 / ID ISC.LRU1000

The maximum permissible exposure (MPE) for general population is defined as 0.6mW/cm2
( f / 1500, FCC OET Bulletin 65, Supplement B). The distance from the transmitting antenna
where the exposure level reaches the maximum permitted level is calculated using
equation (1):


                            EIRP
                     S=                                                           (1)
                          4 ⋅π ⋅ R2
       where:        S = Power density 0.6mW/cm2
                     EIRP = Power output of an isotropic antenna 4W
                     R = Distance to the centre of the radiation of the antenna


Solving equation (1) the minimum distance at which a person must keep away in a
uncontrolled exposure is


                     R = 23cm




The maximum permissible exposure (MPE) for controlled exposure is defined as 3mW/cm2
( f / 300, FCC OET Bulletin 65, Supplement B). Solving equation (1) where S = 3mW/cm2 the
minimum distance at which a person must keep away in a uncontrolled exposure is


                     R = 10,3cm
