A portable collocated transmitter can be operated simultaneously with the WWAN transmitter
provided the individual SAR results for the portable collocated transmitter are less than the value
specified below based on Section 4)a) of the Supp note for FCC KDB 616217 D03. The
maximum individual SAR value is based on the worst case SAR recorded on the external
antenna at 2.5cm (0.374 W/kg).

For mobile collocated transmitters operating greater than 1 GHz, mobile collocated transmitter
can be operated simultaneously with the portable WWAN transmitter, provided the individual
MPE results for the mobile collocated transmitter are less than the value specified below based
on Section 4)a) of FCC KDB 616217 D03. The maximum individual SAR value is based on the
worst case SAR recorded on the test antenna at 2.5cm (0.374 W/kg).

If the summation of SAR exceeds the FCC limit, collocation is permitted through a Class I
permissive change provided the minimum allowable separation distance derived from the
equation below is satisfied. An alternate equation provides the maximum collocated SAR based
on a specified separation distance. In addition, the sum of the highest MPE must be less than the
corresponding MPE limit as defined in section 4. B) ii) of FCC KDB 616217 D03.
