RF Exposure
The equipment under test (EUT) is a Hatch Baby Grow with Bluetooth function
operating at 2.4G Band. The EUT can be powered by DC4.5V (3 x 1.5V AA
batteries). For more detail information pls. refer to the user manual.

Bluetooth Version: 4.1 BLE (single mode)
Antenna Type: Integral antenna.
Antenna Gain: 0dBi.
The normal radiated output power (e.i.r.p) is: 1.5dBm (tolerance: +/- 4dB).
The normal conducted output power is 1.5dBm (tolerance: +/- 4dB).
Modulation Type: GFSK.

According to the KDB 447498:
The Maximum peak radiated emission for the EUT is 100.4dBµV/m at 3m in
the frequency 2440MHz
The EIRP = [(FS*D) ^2 / 30] mW = 5.17dBm
which is within the production variation.

The Minimum peak radiated emission for the EUT is 94.9dBµV/m at 3m in
the frequency 2402MHz
The EIRP = [(FS*D) ^2 / 30] mW = -0.33dBm
which is within the production variation.

The maximum conducted output power specified is 5.5dBm =mW
The source- based time-averaging conducted output power
=3.5* Duty cycle mW =3.5 mW(Duty cycle ≤100%)
=3.5 mW

The SAR Exclusion Threshold Level:
= 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz)
= 3.0 * 5 / sqrt (2.480) mW
= 9.53 mW

Since the source-based time-averaging conducted output power is well
below the SAR low threshold level, so the EUT is considered to comply
with SAR requirement without testing.
