INTERTEK TESTING SERVICES

For Maximum Permissible Exposure (MPE) evaluation of the base unit, the
maximum power density at 20 cm from this mobile transmitter shall be less than the
General Population / Uncontrolled MPE limit in OET Bulletin 65.

For the base unit of tested model of 25825, the maximum field strength measured
(FS) was 111.3 dBμV/m. The distance (D) between the antenna and the equipment
under test (EUT) was 3 meters. And the maximum source-based time-averaging
duty factor in one-handsets operation is 8.33%. From these data, the exposed power
density at a distance (R) of 20cm from the center of radiation of the antenna can be
calculated according to OET Bulletin 65 as follow:

The radiated power = (FS*D)2 / 30
= 40.47 mW

The radiated (EIRP) source-based time-averaging output power
= (40.47 * 0.083) mW
= 3.37 mW

The power density at 20 cm from the antenna
= EIRP / 4πR2
= 0.0007 mW cm-2

In the frequency range of 1,500 - 100,000MHz, the MPE limit is 1.0 mWcm-2 for
general population and uncontrolled exposure. As the measured power density at
20cm from the transmitter is lower than the MPE limit, the compliance to the MPE
limit can be ensured by indicating the minimum 20cm separation between the
transmitter's radiating structures and body of the user or nearby persons.

The following RF exposure statement is proposed to be included in the user manual:

“ FCC RF Radiation Exposure Statement
Caution: To maintain compliance with the FCC’s RF exposure guidelines, place
the base unit at least 20cm from nearby persons.”
