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 and meet the requirement listed in KDB447498.

For the 1.9GHz DECT Babyphone - Baby Unit of tested model: SCD720, the measured
powers among all the measured channels were within its production tolerance: +16 dBm
(Minimum) and +20.4 dBm (Maximum).The antenna gain of SCD720 is 0 dBi = 1.00 (num
gain) and its maximum source-based time-averaging duty factor is 8.3% (2/24 x100%). From
these data and its operating configuration – Mobile device, 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 Conducted Power = 20.4 dBm
= 109.6 mW

The Conducted Power source-based time-averaging output power
= (109.6 * 0.083) mW
= 9.1 mW

The power density at 20cm = 9.1 *1.00/ 4πR2
= 0.0018 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 baby unit
at least 20cm from nearby persons.”
